Problem: long delay (10 sec) between asterisk take a call and dial to remote extension.
Now use realtime pjsip config (for endpoints, aors, auth, contacts) but non-realtime (all in pjsip.conf) has same behavior. Same as aster 15.6
Logs of normal and problem calls (cant attach):
Dont heve this problem by use chan_sip.
Please, tell me, what kind information I can get to you for resolving
