when i do it in my local machine, everything works fine . But i dont know why it makes problem in amazon instance
Thanks in advance

Probably a firewall problem. Also some versions of X-Lite have broken re-invite handling, and will drop a call after about 20s.

You need to get a SIP trace to find out which packet is failing to get through.

I would never recommend running Asterisk on a cloud VM.

Set NAT =yes
it might work for u as it worked for me

david55 · August 6, 2012, 3:00pm

If this is a NAT issue, X-Lite supports STUN, so the correct solution would be to configure that under Accounts | Topology.

nat=yes is a hack in Asterisk that causes it to use the actual source IP address and port, rather than the ones that the protocol is telling it to use. It is for working round misconfigured or broken clients.

Thanks for your reply…

Problem identified and fixed!!

Once i changed dsn name to static ip in externaddr varible in sip.conf conference, i could hear the sound plays on the asterisk server as well as i can chat with other people in the conference without any problem. But in asterisk 1.6 dont have this problem. i mean it works fine with externip=domain_name in 1.6.

Now i have a problem in one to one chat. when we make a call to other user, both user unable to hear any voice from both end. Here is the log from asterisk console.

In-mem exten Trie for Fast Extension Pattern Matching:

       Explanation: Node Contents Format = <char(s) to match>:<pattern?>:<specif>:[matched extension]
                    Where <char(s) to match> is a set of chars, any one of which should match the current character
                          <pattern?>: Y if this a pattern match (eg. _XZN[5-7]), N otherwise
                          <specif>: an assigned 'exactness' number for this matching char. The lower the number, the more exact the match
                          [matched exten]: If all chars matched to this point, which extension this matches. In form: EXTEN:<exten string>
                    In general, you match a trie node to a string character, from left to right. All possible matching chars
                    are in a string vertically, separated by an unbroken string of '+' characters.

You need to fix NCH Software Express Talk 3.10, or its router, so that it sends its public IP address rather than a private one, here:

c=IN IP4 192.168.1.50

Basically, you either need to make it aware that it is behind NAT, or you need a router that is sufficiently SIP aware to fix up the consequences of its not being aware.

Incidentally, dialplan debug is for dealing with rather technical implementation errors, not for run of the mill configuration problems.

Also, I see no evidence of an X-Lite in that trace.
