Hi,
I’ve been registering a couple of Grandstream phones (HT802 & WP825) with FreePBX, and I’ve noticed the Local SIP Port as an option, changes this doesn’t seem to affect the phone being able to register to the PBX, but I do see that it changes what shows in the AOR in Endpoint Manger x-ast-orig-host=x.x.x.x: This Port changes to whatever the Local SIP Port is set to.
Just curious just in case it is important to set.
