MGCP gateway in SRST mode, incoming calls not routing.

Answered Question
Aug 16th, 2010

Hi

I have an MGCP gateway (1861) with SRST configured for WAN failure. There is BRI line connected to it and has a number 3709 3416. The extension numbers in the building are 8XXX (around 13 telephones).

in MGCP mode I have a translation pattern to translate the incmoning calls to 8XXX extensions and all works fine. during WAN failure (simulated) 1861 goes in SRST mode and 8 phones register to it randomly. during this, the incoming calls dont work. outgoing are fine. I have dial peer configured and translation rule for incoming also,

Can anyone help with the troubleshooting?

Here is SRST and dial peer confing

voice translation-rule 1
rule 1 /37093416/ /8904/
!

voice translation-profile SRST
translate called 1

dial-peer voice 1 pots
translation-profile incoming SRST
destination-pattern 0T
incoming called-number .

ip source-address 192.168.0.218 port 2000
max-ephones 8
max-dn 14 dual-line
translation-profile incoming SRST

Any help is appreciated

Thanks and Regards

try to modify your pots dialpeer as follows

dialpeer voice 22 pots

incoming called-number .

translation-profile incoming SRST

direct-inward-dial 

and remove the profile from the call-manager-fallback. Test it out.

Maybe you should take good cara of the Status of Callmanager MGCP gatway  Cause MGCP will turn to Callmanager For Routing Calls.

And you can

show call-manager-fallback

confi ter

no mgcp

mgcp

to see if can be OK

You should lookup on MGCP troubleshoot fr cisco.com
