I’m setting up a new server running Asterisk 11.4.0 and using dahdi driver 2.6.0
When I receive calls from outside via DAHDI (digium TE220 card, with AT&T supplying the T1 PRI), the EXTEN channel variable only gives the last 4 digits of the incoming number – I was expecting at least 7.
Is this a configuration problem (hints to where to look would be appreciated), a driver problem, or a “feature”? Or could it be that AT&T is only sending me the last 4 digits the user dialed?
I can dial any number of digits from an internal phone, and they all show up in the dial plan as expected, and I don’t understand why calls coming in from the dahdi driver should be any different.
