Hi, I was able to place the PBX with kamctl in the ul as contact. I see also, that 4 byte packets are transmitted to the PBX, but ...
unfortunately kamailio use for each outgoing call to the PBX the port 5060 as source. SIP can sort this out by the record and via entries and the callid. This is not possible with the 4 byte ka packets. The PBX awaits keepalives per call, else it terminates the call after arround 15 minutes. I found no hint how to tell kamailio to use different source ports per call. Is there a way? Else I have to send SIP ping, but they can not placed via kamctl, because I can not add all required fields. How should I do the keepalive to the PBX per call in a transparent kamailio proxy?
