I’m working on setting up a SIP trunk to be used just for E911 termination. So, I have a chan_sip trunk called emergency_trunk
set up with a very minimal configuration (below). A call dialed to ‘911’ should be sent to [email protected]
. However, when calls go out the INVITE line gives an address of 911%[email protected]
. That is, the phone number dialed is having @trunkname
added onto it somewhere internally.
This seems like it could be related to SIP proxy support or similar, but I don’t have anything like that configured.
Here’s the PEER details for the SIP trunk called emergency_trunk
:
host=sip.provider.com
type=peer
disallow=all
allow=ulaw,g729
qualify=yes
