I have a pbx with multiple Iax2 trunks over VPNs.
I added a new one with a pbx that belongs to a different local subnet (routed).
All is working except ringing phones on both sides display something like 4569-14342:(extno) as caller ID
Why is this ??? How to get it working like all other trunks (that have same configurations) ?
I combined them, because on reading they seemed to be the same fundamental question just worded two different ways in different threads. Specifically callerid involving IAX2 between different instances.
