Rafik Djabrailov updated ASTERISK-25411:
----------------------------------------

    Attachment: 23-10-2015_debug.txt

Actually, I've reproduced this issue with "Progress" in dialplan and after relatively long uptime. Again, blank PJSIP log in CLI and no active channels on PBX (see 23-10-2015_debug.txt). PJSIP is loaded, but unresponsive - not accepting registrations, no qualifications on contacts, not accepting calls.

Server CPU is almost idle, approx 900 MB free RAM, no extensive tasks running.

Only Asterisk service reload helps to retain normal functionality for the next couple of days or weeks.

> After some time since Asterisk start (may be several hours or days), calls to PJSIP trunks are hanging with no actions or errors. 'pjsip set logger on' command executes, but SIP messages are not appearing in the console completely. 'pjsip show registrations' shows trunks as 'Registered' and 'pjsip show contacts' can display 'Avail' or sometimes 'Unavail' on contacts. It seems that res_pjsip completely hangs in it's last successfull state. 'module reload' executes, but does not help. Only full Asterisk restart brings PJSIP functionality to normal state.
> Maybe this problem can be linked to Internet downtimes, but when Internet brings up, all is functioning on OS level automatically (DHCP, DNS resolutions, default gateway routing, etc).
> I think maybe this problem is somehow related to sip_resolver.c and resolver.c not being executed by PJSIP for some reason.
> As I've noted before, there is no single SIP message in the console, only DEBUG messages (files bad_pjsip_call.txt and good_pjsip_call.txt).
> Also there are some additional debug logs with OPTIONS requests (qualify) to trunk (bad_pjsip_options_request and good_pjsip_options_request).
> Some IPs and numbers are "XXXed" for security reasons.
> PJSIP configure string "./configure --prefix=/usr/local --disable-sound --disable-resample --disable-video --disable-opencore-amr --enable-shared CFLAGS='-O2 -DNDEBUG'"
