Hello,   I am trying to register a Cisco 8841 SIP phone to CUCM 11.5. The phone is on the internet and CUCM is behind a nat device. The phone is able to talk to CUCM and gets all the tftp files (.xml config file, appdials etc) but the phone never sends a registration request to the CUCM. All I see is phone getting the tftp files and then the phone screen saying "registering to server" and i never see a register request come to the CUCM. Is there a way i can check the configuration file for the phone generated by CUCM? How do I troubleshoot this issue? The only message I see in the status messages of the phones is "DNS ipv4 unknown host". I dont think that DNS not able to resolve the CUCM ip address is stopping the phone from registering. Please advise.   Thank you. ... View more

Hello, I have a voice setup where my cisco router is connected to a analog PBX with the FXS ports. The analog phones register to the analog PBX and the PBX forwards those calls to the CME on voice ports. I need to implement FAC for restricted international calling on the CME on the router. I have tested the FAC feature in my lab and it works with analog phone directly connected to CME. My question is would the same configuration work when there is a PBX on the FXS ports and the analog phones are not directly connected the router/CME? Below is my configuration: voice lpcor enable voice lpcor custom group 10 end-users group 11 pin-dial ! voice lpcor policy end-users service fac accept end-users fac accept pin-dial fac ! voice lpcor policy pin-dial service fac accept end-users fac accept pin-dial fac application package auth param passwd-prompt flash:enter_pin.au param max-retries 0 param user-prompt flash:enter_account.au param term-digit # param abort-digit * param max-digits 32 username 666 password 0 12345 voice-port 5 lpcor incoming end-users dial-peer voice 1234567890 pots destination-pattern 1234567890 port 5 dial-peer voice 2 voip destination-pattern .T lpcor outgoing pin-dial session protocol sipv2 session target ipv4:xxx.xxx.xxx incoming called-number . voice-class codec 8641 dtmf-relay cisco-rtp rtp-nte digit-drop h245-signal h245-alphanumeric ip qos dscp ef signaling Thanks! ...

Hello,   I have three Dell 8132 switches stacked and we plan on connecting them to an HSRP pair of Cisco 1921 routers. What would be the best way to uplink these stacked switches to the 1921 pair?    I was thinking of creating vlan trunk from 2 of the 3 Dell switches, one trunk going to each router and enable HSRP on these trunks for the vlans I need to route. Would that be a good approach?   Attached is a basic network of what it would look like. Please suggest if this is a good way to accomplish this or if there is a more better and efficient way to do it?   Thanks   ... View more

Hello,   I have a Cisco 2921/K9 and technology package "securityk9" added to it. But when I try to run "pfr" command on the router it is not available. I assumed SEC/K9 license should give pfr capability on this router. Could you please confirm? I am running "flash0:c2900-universalk9-mz.SPA.152-4.M4.bin" IOS on this router.   License Info: License UDI: ------------------------------------------------- Device#   PID                   SN ------------------------------------------------- *0        CISCO2921/K9          XXXXXXXX   Technology Package License Information for Module:'c2900' ----------------------------------------------------------------- Technology    Technology-package           Technology-package               Current       Type           Next reboot ------------------------------------------------------------------ ipbase        ipbasek9      Permanent      ipbasek9 security      securityk9    Permanent      securityk9 uc            None          None           None data          None          None           None Configuration register is 0x2102   Thank you. ...

Hello, We currently have two ISPs for our internet connectivity and we are load sharing traffic between the two. Currently we have static routing with these ISPs. Our plan is to change that and implement BGP multihoming with the two ISPs. Also currently we have only one router which talks to both the ISP routers. We plan on implementing HSRP pair with this router and use them as WAN/Edge routers which will do BGP with the ISPs.   What is the best/right approach to do this? Since we will be migrating to BGP, we will get new IP space and we need some time to change the applications from current public ip space to new ip space. Should I implement HSRP pair first, do BGP with the ISPs and then migrate the applications to new ip space? Or is there a better approach? Can I have static routing and BGP peering with the ISP at the same time, until I migrate all the applications from current public ip space to new ip space?   Thank you. ... View more

Hello,   What is the best way to implement remote access (ssh) for switch which connects your WAN router and ISP router? Is it good idea to extend your internal VLAN to this switch for you to be able to get to this switch from internal network?   Thank you.     ... View more
