Hopefully someone can help me, here’s the scenario…
We have an Asterisk PC contaning a Digium TE220P ISDN30 card connected to an Avaya IP Office 500 phone system.
Versions we used are:
When we try to dial out from an internal phone, the asterisk only receives the first 4 digits of a 11 digit phone number and then starts to dial out. It doesn’t seem to wait for the rest of the number before it dials. In the logs we see the error “Unexpected Control Subclass ‘5’”
I’ve tried adding overlapdial, relaxdtmf to my zapata.conf but to no avail.
Here’s a link to the full log containing PRI intense debugging.
Can anyone explain to me what this Control Subclass 5 means please?
