I have a new single site setup using UC520. 2 BRI ports are connecting to PSTN. I cannot get BRI work. 'debug isdn q931' shows calls are rejected even if when no calls are made. Please help me understand the debug messages. Debugs are attached. Configurations are as follows:
relavant configurations: ephone-dn are numbered from 1000--1009. 111 is the local emergency number

Hi, it is normal that layer 1 and 2 go down after a timeout. Router or switch will reestablish them as soon there's an active call. Also, which image are you using? You should have XW6 for the UC520.
For the extensions, you can either use an incoming rule like
rule 1 // /1/
or
dialplan-pattern 1 pattern ... extension-length 4 extension-pattern 1...
Hope this helps, please rate post if it does!

can you send output from debug isdn q931?

Hi Kenneth,
It is in the attachment.
Thanks.

Hi,
please configure "isdn static-tei 0" under bri interfaces. Then you can use the trunk-group referencing it instead of port under DP.
Then you can optimize the translation-rules if needed, an alternative is to use "dialplan-pattern" under telephony-service.
In any case when you have rules under trunk group, you don;t need them under voice-port.
Note you don't need:
isdn timer T321 0
isdn send-alerting

I had not seen catched that before, for outgoing, please configure isdn switchtype basic-net3.
For incoming, how do you extensions numbers looks like ?

Hi,
When I change the switch type to basic-net3, bri interface layer 2 and 3 are not up. I am using the only type that can bring up all layer 3 on the interface.
Extention number are 1000, 1002,..., 1021.
Thanks
