[asterisk-users] Asterisk 13 chan_sip trunk appending @string to dialled number

[Brendan Ord]

Hello,

I'm having what seems like a weird issue connecting Asterisk 13 (FreePBX 12) to a Cisco 2811 router via a chan_sip trunk.  Whenever I try dialling out via this trunk, something appends '@CUBE' onto the end of the dialled number, as per the following examples;

Asterisk log;
app_dial.c: Called SIP/test/0429123456 at CUBE
chan_sip.c: Got SIP response 500 "Internal Server Error" back from 172.22.4.12:5060

In the SIP SDP;
INVITE sip:0429920437%40CUBE at 172.22.4.12 SIP/2.0.
To: <sip:0429920437%40CUBE at 172.22.4.12>.

As you can see, the @CUBE carries over into the SIP URI as %40CUBE.  The FPBX trunk name and outbound route were called CUBE (afaik, purely descriptive) but I changed them to something different and the @CUBE persisted.  I'm really not sure where this is coming from, and why.

Here is my trunk configuration;

PEER
type=friend
qualify=yes
nat=no
insecure=port,invite
host=172.22.4.12
dtmfmode=rfc2833
context=from-trunk
allow=ulaw
disallow=all

USER
type=friend
qualify=yes
nat=no
host=172.22.4.12
dtmfmode=rfc2833
allow=ulaw
disallow=all
canreinvite=no

Thanks for any help :)
