[asterisk-users] Asterisk not sending 200 OK

[Rob Schall]

We're trying to get a SIP peer going between our asterisk box and our
provider. It should then ring our phone.

The call does come in and it does execute the extension in the dial
plan. But the provider says they never get a 200 OK back and therefore
they send another INVITE and then after a few seconds drop the call.

Here's our setup:

sip.conf
[ngt-trunk]
type=peer
qualify=yes
port=5060
context=from-trunk
fromuser=603XXXXXXX
host=onecps.onvoip.net
registersip=no
username=WebSolutions
secret=603XXXXXXX
dtmfmode=inband
insecure=very


extensions.conf
[from-trunk]
exten => _6035467131,1,Wait(1)
exten => _6035467131,2,Dial(SIP/4610)
;exten => _6035467131,3,Playback(ws-ivr)
;exten => _6035467131,4,Hangup


The debug looks like:
    -- Executing [6035467131 at from-trunk:1] Wait("SIP/wsol-00820870",

    -- Executing [6035467131 at from-trunk:2] Dial("SIP/wsol-00820870",
