Joshua, come on, you know as me that you have few people around the world
to have the skills and the time to maintain a C module for Asterisk.
For a critical feature like SIP in Asterisk, at least to me, it means that
for a serious production with Asterisk 13, I won't use chan_sip but I'll
prefer chan_pjsip.
Personally, I don't care if it's pjsip or sip, I only want a telephony
stack that won't piss on my shoes under the fire of a big production.

However, I didn't know that some features are missing in chan_pjsip compare
to chan_sip. A list exists somewhere ?

Moreover, by curiosity, somebody has already benchmarked chan_sip
vs chan_pjsip ? Somebody has a noticed an efficiency issue with pjsip ?

Regards.
