I've been trying all afternoon to make some sense of this. The only way I can get it to NAT 5060->5060 is by putting a static NAT route in, which I believe I shouldn't have to do. Any help?

andymccall · ‎01-15-2014

Thanks fo thre reply Daniele. IOS is 15.3(3)M, but I've updated this today from an ealier version hoping to fix the problem. If I do the following: 877va-1#show ip nat translations | include 5060 udp 82.70.85.118:1029 192.168.1.254:5060 212.23.7.228:5060 212.23.7.228:5060 877va-1#clear ip nat trans 877va-1#clear ip nat translation * 877va-1#clear ip nat statistics Then on the CME box, re-register the sip-ua. 877va-1#show ip nat translations | include 5060 udp 82.70.85.118:1030 192.168.1.254:5060 212.23.7.228:5060 212.23.7.228:5060 It takes the next port. Its never using 5060 in the first place from what I can tell

I *finally* got incoming calls working today! Yes, no static route was needed. There were a few different problems. The only two things I have left to work on are: Calls coming in via SIP that are forwarded on noan to a mobile connect, but don't have any audio (not sure if this is a transcode or a NAT issue). I've temporarily got around this by diverting via the POTS line, rather than the SIP trunk. BLF pickup doesn't work, you have to press Pickup then the BLF button, I was under the impression I should just be able to pickup the call by pressing the BLF key. Thanks for the help.

Thanks for the reply Carlo, I've attached the output of a debug ccsip messages, the call completed fine. At the moment when trying to make an incoming call nothing hits the CME at all, but I wasn't sure if it should as there are no static routes. Call me stupid, but how can the call come through to the CME if there are no static routes? Should the NAT handle this automatically once the outgoing sip trunk has been registered? Maybe I'm looking in the the wrong place - it looks like the dial peer isn't even up - should the OPER PREFIX say up? 2611xm-1#sh dial-peer voice summary dial-peer hunt 0 AD PRE PASS OUT TAG TYPE MIN OPER PREFIX DEST-PATTERN FER THRU SESS-TARGET STAT PORT 100 pots up up 8T 0 up trunkgroup VIC2-2FXO 200 voip up up 9T 0 syst dns:voip.zen.co.uk 150 voip up down 0 syst dns:voip.zen.co.uk 20001 pots up up 8882$ 0 50/0/1 20002 pots up up 01xxxxx8882$ 9 50/0/1 20003 pots up up 8883$ 0 50/0/2 20004 pots up up 01xxxxx8883$ 9 50/0/2 20005 pots up up 8884$ 0 50/0/3 20006 pots up up 01xxxxx8884$ 9 50/0/3 Thanks,

Hi Folks, I've got to the point where I'm thinking of giving up on the hardware I've got because I don't think it will work, which is strange as I would have thought for a small business this would be a common configuration, unfortunately it means I'll be moving to something like DrayTek (I'd prefer to stay with Cisco though). So this is my final attempt at getting this working! SIP TRUNK-> Cisco 877 (NAT'ing) <--> Cisco 2611XM & CME 4 Internal calls are working Outgoing calls via SIP trunk and PTSN are working Incoming calls fail My configuration on the CME is: voice service voip allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip no supplementary-service sip moved-temporarily no supplementary-service sip refer sip header-passing registrar server outbound-proxy dns:voip.zen.co.uk voice translation-rule 1 rule 1 /^9$.*$/ /\1/ voice translation-rule 2 rule 1 /.*/ /01xxxxx8882/ voice translation-profile SIP translate calling 2 translate called 1 voice-port 1/0/1 no comfort-noise voice-port 1/1/0 trunk-group VIC2-2FXO supervisory disconnect dualtone mid-call no battery-reversal no comfort-noise cptone GB timeouts call-disconnect 5 timeouts ringing 90 timeouts wait-release 5 timing digit 80 timing inter-digit 80 connection plar opx 1001 ! voice-port 1/1/1 no comfort-noise ! dial-peer voice 100 pots trunkgroup VIC2-2FXO description PSTN Dial Peer destination-pattern 8T incoming called-number . no sip-register ! dial-peer voice 200 voip description SIP Outgoing Dial Peer translation-profile outgoing SIP destination-pattern 9T voice-class sip outbound-proxy dns:voip.zen.co.uk session protocol sipv2 session target dns:voip.zen.co.uk session transport udp dtmf-relay rtp-nte codec g711ulaw no vad dial-peer voice 150 voip description SIP Incoming Dial Peer voice-class sip outbound-proxy dns:voip.zen.co.uk session protocol sipv2 session target dns:voip.zen.co.uk session transport udp dtmf-relay rtp-nte codec g711ulaw no vad ! gateway timer receive-rtp 1200 ! sip-ua authentication username 01xxxxx8882 password 7 xxxxxxxxxxxxxxxxxxxxxxxxxxxx registrar dns:voip.zen.co.uk expires 3600 sip-server dns:voip.zen.co.uk host-registrar permit hostname dns:voip.zen.co.uk permit hostname dns:asterisk01.voip.zen.co.uk permit hostname dns:asterisk02.voip.zen.co.uk ephone-dn 1 dual-line number 8882 secondary 012xxxx8882 no-reg both label Andy McCall name 012xxxx8888 call-forward noan 90xxxxxx188 timeout 30 I've taken out all of the settings from my 877, so at the moment its just NAT'ing for outgoing. no ip nat service sip udp port 5060 ip nat inside source list 1 interface Dialer1 overload ip route 0.0.0.0 0.0.0.0 Dialer1 ip route 192.168.2.0 255.255.255.0 192.168.1.254 ! access-list 1 permit 192.168.0.0 0.0.255.255 The things I've tried that people have suggested and I've read about: Adding a static route for 5060 to 192.168.1.254 to the 877 - this gets traffic to the CME, but the call doesn't ring and I get an INVALID HOST problem because the SIP trunk's IP addresses are not registered on the CME Adding the external IP's of the SIP provider to a loopback device - this stopped all calls working as all traffic that was ment for the SIP trunk, went to the loopback device Binding control and media source interface to FastEthernet0/0.1 - no changes Please can someone help me, or is it simply a limitation of Cisco equipment that it can't work behind NAT? Thanks!

Hi, I've got a Cisco 877 Router connected directly to BT Infinity Broadband (FTTC) and I have 8 external IP addresses. This is working fine using the following config that only uses 1 of those IP addresses: interface Ethernet0 no ip address ! interface Ethernet0.101 encapsulation dot1Q 101 pppoe enable group global pppoe-client dial-pool-number 1 ! interface ATM0 no ip address shutdown no atm ilmi-keepalive ! interface FastEthernet2 description ** Trunk Port ** switchport mode trunk no ip address ! interface FastEthernet3 description ** Trunk Port ** switchport mode trunk no ip address ! interface Vlan1 ip address 192.168.1.1 255.255.0.0 ip nat inside ip virtual-reassembly in ! interface Dialer1 description ** Zen Fibre ** mtu 1492 ip address negotiated no ip redirects no ip unreachables no ip proxy-arp ip nbar protocol-discovery ip flow ingress ip nat outside ip virtual-reassembly in encapsulation ppp ip tcp adjust-mss 1452 dialer pool 1 ppp authentication pap chap ms-chap callin ppp chap hostname xxxxxxx ppp chap password 0 xxxxxxx ppp ipcp address accept no cdp enable ip nat service sip tcp port 5060 ip nat inside source list 1 interface Dialer1 overload ip route 0.0.0.0 0.0.0.0 Dialer1 ip route 192.168.2.0 255.255.255.0 192.168.1.254 ! access-list 1 permit 192.168.0.0 0.0.255.255 I've also got an old 2611XM router running CME 4.1 (hence the ip nat service sip tcp port 5060 command). The CME is set up and working, but at the moment I can't accept incoming calls. After much configuration trying NAT (as I know NAT to a point!) I don't think its possible with this version of CME that I'm using because CME won't accept the incoming SIP requests as the IP's are wrong due to NAT. Rather than spend anymore time trying with NAT I want to take one of those external IP addresses, and place it directly on my 2611XM, then set it so the only IP address that can connect to my 2611XM is the SIP trunk provider. The only think is, I've never really done anything like this and I'm not sure where to start I think I need to set the rouer to be directly on the internet by bind the IP address to the routers interface: interface FastEthernet0/0.1 description data encapsulation dot1Q 1 native ip address 82.70.85.113 255.255.255.255 Then somehow use a BVI to move that IP from the 877 to the 2611XM while also creating an access list that only allows 212.23.7.226 - 228 to allow to connect to 82.70.85.113. Can anyone help me out please? Finally, if this isn't possible, I do have an ASA 5505, but I haven't touched ASA/PIX ever. I bought it with the intention of studying for CCNA Security, but haven't got around to it yet as I'm looking at CCNA Voice first. Thanks!

Anyone able to help with this one?

andymccall · ‎11-05-2013

I've been playing with this, and still not managed to get it working! :-( On my 2611XM I've added: interface Loopback0 ip address 212.23.7.227 255.255.255.255 secondary ip address 212.23.7.226 255.255.255.255 secondary ip address 212.23.7.228 255.255.255.255 no ip route-cache Then changed my voice service voip to: voice service voip allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip no supplementary-service sip moved-temporarily no supplementary-service sip refer sip bind control source-interface FastEthernet0/0.1 bind media source-interface FastEthernet0/0.1 registrar server outbound-proxy dns:voip.zen.co.uk I also removed the static nat association so my NAT is now: ip nat inside source list 1 interface Dialer1 overload ip route 0.0.0.0 0.0.0.0 Dialer1 ip route 192.168.2.0 255.255.255.0 192.168.1.254 ! access-list 1 permit 192.168.0.0 0.0.255.255 In this configuration, no calls work. I f I remove the loopback interface, outgoing calls work again. If I add the the following to the 877: ip nat inside source static udp 192.168.1.254 5060 82.70.85.118 5060 extendable I can get an incoming call to ring a phone, but the call can't be established (plus, there's no security on this and I can occasionally see other people try and bounce calls through my CME). I think what I need to do is put static NAT on so I can only accept calls from 212.23.7.226/7/8 never any other addresses and forward this to my CME box, then tell the CME to ignore the loopback interfaces and send calls out via fa0/0.1 - its difficult as I'm using CME 4.1 and some commands don't work. I supose the only other option I have is using a bridge (again with an ACL for those IP addresses) and placing an interface on the CME directly on the Internet, but this is far beyond my skills at the moment! I'm really stuck with this now, please can someone help?! Thanks!

Worked it out. My FXO port is 1/1/0, not 1/0/0 :-)

Hi Folks, I'm trying to get an incoming POTS call to ring a single phone while studying for my CCNA Voice. At the moment I'm struggling and when I call the POTS number I'm getting a dial tone, I can then dial the internal extension, but I want it to go straight to extension. The configuration I have is: voice-port 1/0/0 cptone GB connection plar 1001 caller-id enable dial-peer voice 100 pots description PSTN Dial Peer destination-pattern 9T incoming called-number . ephone-dn 1 number 1001 label Living Room name Living Room ephone 1 device-security-mode none mac-address 0014.69E0.51F5 type 7970 button 1:1 2:2 3:3 Can anyone help me get this working please? I can't dial in or out at the moment, so its a bit of a failure!

Hi Folks, I'm trying to get a single 7970G phone to register against a 2611XM running CME 4.3 as part of studying for my CCNA Voice. I've done lots of reading around and come up with the config attached, but the phone I've got just sits at the Upgrading screen when its plugged in. I think I'm missing something fairly important on my config. I'm not even sure if its getting an IP address from the DHCP server... At the moment, the hardware is configured 2611XM-fa0/0->PSU Brick->Phone. Please can someone take a look and point me in the right direction? Thanks, Andy McCall
