I have the following config for my phone solution:
3 Basic rate ISDN lines
1 Mobile BRI Router for Mobile/ Cellphones.
I have run several tests calling various ISDN lines to try and hit the autoattendant. with no calls active on the router I am still getting intermittent engaged tones and calls just dropping off. i cannot figure out whats going on. my phone system config seems fine but still calls keep getting dropped.
Collect the following for a failure and we can take a look:
debug voip ccapi inout
debug isdn q931
debug ccsip mess
Collect logs via:
Router(config)# service sequence Router(config)# service timestamps debug datetime msec Router(config)# logging buffered 10000000 7 Router(config)# no logging con Router(config)# no logging mon Router(config)# voice iec syslog Router# term len 0 Router# sh logg
