external calls disconnect

Answered Question
Aug 21st, 2008

CM 6.1

Phone 7937

I have installed a 7937 and internal calls in and out work fine

external incoming calls works fine

but external outgoing calls will ring but disconnect as soon as the user connects - have checked the config but cannot understand why this happens?

any ideas?

thanks in advance

I have this problem too.

what codec are you using for the outgoing calls and are you using MGCP or H323?

sounds like a codec issue

You'll need to give me the config of the PSTN gateway. Is this FXO, PRI or T1?
