Not sure if this is an Asterisk or FreePBX thing.
I am currently building a new server to replace our A11 box and have installed A13 with the FreePBX distro.
I have set our trunk up and can get incoming, but on outgoing the TCPDUMP is showing a %40[trunkName]
So it is sending INVITE sip:[rangNumber]%40[trunkName]@[IPofTrunk]:5060 SIP/2.0
(Ignore the , just there for demarcation)
I cant think what setting would cause this, I know %40 is @ but not sure where it is being told to inject this!
Any light shed would be greatly appreciated
