[Freeswitch-dev] FS send re-invite about every minutes, is there a way to disable it?

[seven du]

Got it.

because I'm behind an NAT and

#define SOFIA_NAT_SESSION_TIMEOUT 20


  515     if (switch_test_flag(tech_pvt, TFLAG_NAT) ||
  516         (val = switch_channel_get_variable(channel, "sip-force- 
contact")) ||
  517         ((val = switch_channel_get_variable(channel,  
"sip_sticky_contact")) && switch_true(val))) {
  518         sticky = tech_pvt->record_route;
  519         session_timeout = SOFIA_NAT_SESSION_TIMEOUT;

so, session_timeout would always be 20 and I always get a Session- 
Expires header with value 120(the default value maybe).

Based on http://tools.ietf.org/html/draft-ietf-sip-session-timer-15, I  
think #define SOFIA_NAT_SESSION_TIMEOUT 20 maybe not followed the  
standard. Anyway, OPTION packets works well for NAT KEEP-ALIVE right?

Do we really need line 519(as the above code)? or should we make  
another setting parameter say "nat_session_timeout" in sofia profile?  
Do I need to post this on jira?
