SIP Invite Missing User Part

Hi There,

This is my first post, so be gentle.

I have been using FreePBX as a B2BUA for a while and its excellent. However, I have now enabled an extension. Pretty basic setup. Inbound DDI 0207xxxxxxx and the extension number matches this DDI.

However, when I dial the number I noticed the device is returning 404 not found. I traced the SIP and notice the SIP INVITE message is missing the “SIP to address User Part:”. The SIP To Address just states “sip:”.

Any ideas what I am doing wrong?

Many Thanks in advance.


What is the setting for “Set Destination” on the Inbound route? Is it set to ring that extension
