Asterisk 1.6+TLS --> call hung up suddenly after 30's

Hi all…

i’m trying to configure TLS enable on my asterisk 1.6. and i think it was done, because i’ve already can make a call beetween A to B. but the problems came up.

  1. when A call B, then B answered the call, in A side there was still a notification “RINGING” in the softphone (i use miniship ubuntu as my softphone)
  2. after 30’s, the call suddenly hung up

i tried to check the SIP and extension.conf, but still i can’t figured out why…
and before i implemented the TLS on my asterisk, i’ve also already made a call, and it was worked. i didn’t found any problems on it…

here’s what i have in my network:

  1. server : asterisk 1.6 runs on ubuntu 9
  2. router : mikrotik
  3. client : use MINISIP softphone on ubuntu

i hope there will be a solving problem for my issue…
i;ll be very gratefull and appreciate for all answers…

best regards
