SRST in IOS12.4(3e)

[cjrchoi11]

I'm testing SRST in 3745 IOS12.4(3e) and want to know how can I configure.

!

application

global

service alternate Default

!

dial-peer voice 1 pots

service mgcpapp

incoming called-number .

direct-inward-dial

!

Cannot inbound call into the ephone if I confiugre the "service mgcpapp" on the dial-peer but works okay if I remove it. Is the "service mgcpapp" command not required in IOS12.4(3e).

Thanks in advance,

When you use SRST with MGCP you need to include portions of a H323 config as it falls back to H323 when SRST kicks in. Have you included the "ccm-manager fallback-mgcp" & "num-exp" statements and the call-manager-fallback section?

I didn't post the rest of configiration since my question is just for the "service mgcpapp"

Pretty sure you dont the service mgcpapp command on the dial peer after 12.3(11) or somewhere around there.

You would need:

ccm-manager fallback-mgcp

And a dial peer for outbound calls. 0T or 9T etc.

There are plenty of other things to customise too. Post the rest of your config - mgcp, call-manager-fallback etc if you need more advice.

Cheers,

Tim
