I have Asterisk installed with six SIP extensions and three ZAP extensions on a Digium TDM31B. The callerid from both internal extensions and pstn always shows up as the last ZAP extesnion configured. For example, any internal or external call will appear as being from channel 3 if I have three ZAP extensions configured. It appears from channel 2 if I only have to ZAP extensions configured. If I remove all of the ZAP extensions then callerid works fine.
I’ve Googled up the wazoo and searched this forum to no avail… Any ideas?
