Going PJSIP

I think a lot of the problems stem from using a system behind a dynamic IP Address so I am using dns to locate the system, this is working absolutely fine for chan_sip, and seems fully supported, but I do remember reading somewhere that it is not in pjsip.

PJSIP was indeed lacking the “externhost” functionality which is a major bummer for using Asterisk with dynamic IPs behind NAT. Fortunately, Joshua Colp has become the Hero of the NATion and implemented it (https://gerrit.asterisk.org/#/c/6069/)

The functionality of using dynamic host adresses for external_media_address and external_signaling_address should therefor soon be available. Looks like Asterisk 14.7 and 13.18 are the versions that will come with this feature.

From what I understand the refresh time will be configurable in /etc/asterisk/dnsmgr.conf (like the “externrefresh” in chan_sip).

If that is the case then it will be perfect. I have stayed with Chan_Sip because of the dynamic IP problem so as soon as this becomes available I will get a PJ_Sip system up and running and start testing it.

Thanks for the heads up.
