Cisco 2851 w/ CME 8.x & SIP Trunk via Vitelity

gcrawford2005 · ‎12-15-2013

I have a Cisco 2851 loaded with DSPs and it has an internet connection to support the SIP trunk to Vitelity. Below are the appropriate sections of my config for this setup. I am running CME in both SCCP and SIP which is why i have some SIP bind to interfaces.

Here are the things i would like to get functioning...

- Incoming calls working properly... Currently i get a slow busy when I try to call my DID at Vitelity. Outgoing works correctly.

- Outgoing callerID setup correctly. How do i specify a static # and how do i specify 123456XXXX like CM works.

- Currently when i dial out i don't have to dial 9... 9 doesn't work to dial out, just regular dialing.

you are receiving INVITE message from this ip: 66.241.99.90. have you configured this ip in cme to accept the sip connection?

//Suresh Please rate all the useful posts.

Ayodeji Okanlawon · ‎12-30-2013

Like Suresh said, this looks like toll fraud prevention. You need to add the ips of your sip provider to your ip addres trusted list

voice service voip

ip address trusted list

ipv4 66.241.99.90 X.X.X.X where x.x.x.x = subnet mask of the ip

I added the below to cover my basis since my SIP provider has an IP range and I am using DNS names instead of IPs for the connection. Still getting a slow busy when calling the outside number. From my SIP provider i get a message saying... "We received 'CONGESTION' when attempting to route the call to your server or device." At the bottom is a new debug log of whats happening. Just a side note, i do have an ASA 5505 between the internet and my 28xx router.

Suresh Subramanian · ‎12-30-2013

When the gateway processes an initial INVITE, a determination is made whether or not the host portion is in IPv4 format or a domain name.

If the host portion is an IP address, its IP address is compared with the interfaces on the gateway.

If a match is found, the INVITE is processed as normal.

If there is not a match, the gateway sends a 400 Bad Request – `Invalid IP Address' message

could you please verify 'MYexternalIP' is configured? are you doing any NAT?

//Suresh Please rate all the useful posts.

gcrawford2005 · ‎12-30-2013

MYexternalIP is my ISPs IP assigned to the WAN interface of my ASA5505. The 28xx sits on the LAN side of my ASA on a 10.x.x.99 IP. The ASA is doing NAT between the outside and inside. Does that answer the question? On my SIP providers side there is an option to enable NAT and that is currently turned on and believe it gets set when the box registers itself.

gcrawford2005 · ‎01-03-2014

Did the above make sense to anyone? If anyone is availible over the weekend i'd really like to resolve these issues. I'd be willing to compensate someone for their time, just PM me or reply.

Thanks,

Ayodeji Okanlawon · ‎01-04-2014

From the logs, the external IP was not natted to the internal IP of your gateway. The ASA sent the packet as it is, hence the gateway is rejecting the call as Suresh already mentioned. You need to ensure that the externalIP is Natted to gateway's IP before the INVITE is sent to it..

So i'm not quite following this... I have my ASA 5505 between the Internet and Inside doing nat from Public IP -> Internal IP range. I have a single static IP on the outside, which the ASA is using. Other computers on my Internet Vlan get to the internet just fine with the nat in place for 10.0.0.x to translated to my ASA's outside IP. Do I need to setup NAT on my Cisco 2811 Router thats doing SIP to translate its internet IP to the external IP? If this is the case will that affect any Lan traffic between the router and the phones? or am i completely missing something?
