I configured a PBX with Asterisk Wildcard TE121 and PRI ISDN.
i have N numbers and unfortunately I have the problem that when I try to go out through ISDN with an internal sip, from outside you’ll see a single number for all internal sip.
I set up my internal sip so.
callerid in output options 06xxxxx800 - 06 is national prefix
I also tried without 0, 6xxxxx800 but without success, I always see as a number in output 06xxxxxx790.
It’s pissing me off!!
Is there anything I should do this as well as setting in the configuration sip?
I hope in you.
