[Asterisk-Users] MGCP and Cisco ubr924

[Joe Cooke]

I've been trying to figure this one out for a while, but to no avail.

I have my cisco ubr924 setup for MGCP with Asterisk as the call-agent.  I have manually registered the endpoint in mgcp.conf.  When I pick up the phone, I get no dialtone and debug shows errors.  IOS on the ubr924 is 12.2.

Any help is appreciated.

from mgcp.conf:

[ubr924] 
host=65.37.86.203
context = from-sip (just as a test context)
line => aaln/0 
line => aaln/1
