SRST PRI

What can be the problem, that SRST works fine only localy (phones calls in FALLBACK mode). But phones didn't see any PRI channel. Can this depends on some license or IOS version?

All configuration of router done right as I suppose.

Re: SRST PRI

Are you using MGCP? If so, do you have the "call-manager fallback-mgcp" command? Do you have a POTS dial peer pointing to the PRI? Do you have one of the following depending on your version of IOS?

For Cisco IOS Software Release 12.3(13)T or earlier:

call application alternate DEFAULT

For Cisco IOS Software Release 12.3(14)T or later:

application

global

service alternate Default

Take a look at the following link.

Hope this helps. If so, please rate the post.
