Usereqphone=yes seems to don't work

Sangoma Trunking
1

A service provider requires user=phone in FROM uri like this example they send to me

INVITE sip:xxxxxxxxxx@ispsipserver;user=phone SIP/2.0
From: <sip:xxxxxxxxxx@client ispsipserver;user=phone>;tag=123456
To: sip:xxxxxxxxxx@ispsipserver;user=phone

I am using sangoma linux FreePBX 14.0.3.6 & Asterisk 15.4.0

What i tried:

  • Added usereqphone=yes in the sip trunk but user=phone is added in TO but its not added in FROM
  • In Settings > Asterisk sip Settings > Chan SIP Settings> Other sip Settings added usereqphone=yes - no changes

I am new to voip branch and wish someone can explain, maybe i am doing something wrong or this is a bug…

couldn’t add this because of error from forum “Sorry, new users can’t put links in posts.”
