hello
 i would like to ask if there is a possible way to change change connnection headers for external sip profiles..
my provider complain

with the following
Your SIP Contact header must be presented like: 

sip:330591@my-external-ip but you have it configured as:
 the following is the defaulft configuration  of freeswitc.
sip:gw+voipdito@my-external-ip this is wrong.

 is there any way to format that contact headers in freeswitch?

thank you in advanced.
