I have CCM ver.5 and 2811 gateway connected through VPN tunnel (Easy VPN).
I advertised LAN network on the remote gateway and its reachable through the Call-Manager, but we couldn't advertise the WAN (VPN tunnel IP) because its variable..
So we can't ping (normal Ping) to the call-manager from the gateway but we can ping using the extended ping with LAN IP address as the source.
The MGCP is down and can't reach the call manger, but if we can change the MGCP source interface I think this will solve the issue.
Can you help to solve this problem.
Do you have the mgcp bind commands in there?
i added them but still facing problem.
please find attached, debug mgcp , show run , show ccm.
Thnaks in advance for your help
You have a connectivity issue.
Either these packets aren't getting there, aren't allowed through the VPN, or the responses for them aren't getting back through the VPN.
Please make sure that UDP 2427 and TCP 2428 are allowed on your VPN.
From the debug, I saw this:
*May 4 05:52:27.675: MGCP Packet received from 10.226.100.10:2427--->
510 is a MGCP Response Code. Means that transaction could not be executed because a protocol error was detected.
Could you share us your MGCP configuration in CM?
If a domain name is configured on the MGCP gateway, the domain name for the gateway configuration on Cisco CallManager must be the same. In your gateway you have hostname Hulul-Amman and ip domain hulul.com, but in CM you have only Hulul-Amman.
If the domain names for the MGCP gateway and the gateway configuration on Cisco CallManager do not match, perform one of these actions:
* Change the domain name on either the MGCP gateway or Cisco CallManager so that they both have the same domain name.
* If either hostname or domain name is changed on the MGCP gateway, issue these two global commands in sequence on the MGCP gateway in order to implement the new hostname or domain name:
Try to reset the gateway voice ports if you encounter issues with the Cisco IOS gateway registration or operation:
Check if your gateway endpoints show registered in CM.
Hope it helps.
Thanks for you.
Please note that I made some edits and trial before on the Gateway regarding the domain name and it's the same , Hulul-Amman.
i made everything and the problem still come into view
The debugs show that your gateway has .hulul.com
but the screenshot doesn't.
Regardless, the debugs also show that the MGCP gateway isn't getting any responses. Check your routing.
Have you checked this bug due to the 510 error message
