gegan Posted September 14, 2009 Report Share Posted September 14, 2009 My ITSP has requested that the account username be send in the INVITE for each outgoing call for authentication purposes. I thought I had setup the trunk correctly as the REGISTER succeeds (Status 200) but when I try to make a call I get 400 Bad Request. When I look at the INVITE request in the SIP from field it has '40@localhost'. What the ITSP wants is username@your_pbx_IP address. How can I configure this. Thanks, George Quote Link to comment Share on other sites More sharing options...
