[Freeswitch-users] When using nimbuzz, call disconnects after 90 seconds with RECOVERY_ON_TIMER_EXPIRE

[Anton VG]

Please help,

While other SIP clients works well, there is a problem with nimbuzz
SIP client, which quite frequently used by 'not-advanced' users. seems
It which works through their services (asterisk 1.6)

This problem was not happening while I have been using Asterisk too,
but after recent migration to FS - it does.

nimbuzz client stays like online, just sound disappears, but there is
a confirmation from nimbuzz server side, regarding the BYE

most likely a NAT issue, but if the same time using Asterisk on the
same server - there is not problems. So might be there any options to
tune?

there are some SIP activity like this before calls disconnects, no replies:
