Inbound Hangs up right away

My outbound works fine always. However,90% of the time on inbound, my 1 DID for testing on my sip phone will ring once, then hangs up. Even in

that second, I am not able to answer if I do manage to get it in time. I have my registration line in my sip.conf and the rest below. Firewalls

have been turned off and I can not find a reason why it is hanging up. Internal extension functionality works fine. I setup another test

extension to listen to music on hold, and it works flawlessly. I’m fairly new, so any assistance would be appreciated.

[8000]
type=friend
host=dynamic
context=inbound

extensions.conf

exten => 18xxxxxxxxx,1,Answer()
exten => 18xxxxxxxxx,n,Wait(2)
exten => 18xxxxxxxxx,n,Dial(SIP/8000,15)
exten => 18xxxxxxxxx,n,Hangup

== Using SIP RTP CoS mark 5
– Executing [18xxxxxxxxx@inbound:1] Answer(“SIP/ITSP-00000000”, “”) in new stack
– Executing [18xxxxxxxxx@inbound:2] Wait(“SIP/ITSP-00000000”, “2”) in new stack
== Spawn extension (inbound, 18xxxxxxxxx, 2) exited non-zero on ‘SIP/ITSP-00000000’

From the sip debug, the only thing I get that looks out of the ordinary is: Call leg/transaction does not exist

I have masked out the DID & ITSP for privacy reasons. Anyone have any suggestions on what I can try or where i can go from here?

hi,

it is worthwhile to specify the codec in sip.conf. if phone rings, but voice is not putting through, it might be due to codec mismatch.

I appreciate the help because I still haven’t gotten it figured out. My sip provider had me put these two lines in my general context in sip.con since it’s what they’re passing through.

allow=ulaw
allow=g729

Any other thoughts? Since it does ring every single time. It’s just 90% of the time, it rings once, and thats it. Any help is appreciated.
