Hi All, not sure why I can't call out the config is attached and would appreciate help.
Incoming calls work fine, so I guess the ISDN config is fine. When I dial the following local number: 902920nnnnnn (n = number between 1-9) unknown number is displayed on the phone, I can't see why the dial peer is not matched. I'm thinking there is an issue with other parts of the config.
Hi, your only active DP for call, tries to match 920 followed by six digits, it that right ?
If you want to see why that fails, enable "debug isdn q931" with "term mon".
Either use forward-digits 8, OR prefix 20.
In many countries it's also possible NOT to use any prefix digit for external calls, users like that very much because it's like calling from home, just make sure all the internal extensions begin with a digit not used by your contry dialplan.
Hi, this is the debug output:

Possibly the switch doesn't like the empty calling number. Try removing it altogether, under DP: "clid strip".
Honestly I can't remember which type/plan si needed in the UK. Take a trace for an incoming call and so we can set them the same.
Hi this issue is now resolved, I removed âbearer-cap Speechâ from voice-port 0/1/0 and that was it.
I have another question relating to my configuration and was wondering if you can help? I have extension 500 shared with two phones. Extension 500 also has a voicemail box. When an outside call comes in both phones will ring, if no one answers a call a voicemail is left, but the voicemail lams on two phones are not illuminated.
