SIP trunking problem with Alcatel OmniPCX Enterprise

General Help
1

Hi, I just configured a sip trunk and here is the configuration in Freepbx.

host=192.168.3.78
username=1000
secret=1234567890
type=peer
qualify=yes
context=from-alcatel
insecure=invite,port

When I made a call to Alcatel, I see some strange characters apprended to the SIP header, does anyone know what is that and how to remove? You will see strange characters like %40TO%20OXE appended to the sip invite.

----------------------utf8-----------------------

%40 is @ %20 is a space character thusly it is attempting to translate to " sip:991892637**@TO OXE**@192.168.3.78 SIP/2.0" , which is basically bogus.

Provide a full call log, identify 192.168.3.21 and 192.168.3.78 and what is your context [from-alcatel] ?

apparently, the strange character is gone after I rebooted the server.

Btw, I am looking at implementing SIP/TLS. cannot seems to find any guide. Issit support?
