fxs not work for srst mode

Unanswered Question
Feb 13th, 2008

When we do the srst test, we find fxs ports are not work. We get the busy tone when lift up the handset of analog phone. But, we get normal dial tone when we shut dial-peer voice 999200 pots. Is there any configuration error in below?

Our CCM is 4.1(3)sr3a and version of c2851 is 12.4(15)T1 and srst version is 4.1(0)

Hi,

Try adding

application

global

service alternate Default

This is needed for MGCP to fall over and become an SRST (H323 Gateway).

Hope this helps, if so please rate.

Regards,

Dave
