Hello,

I need to add the User-to-User field to the SIP header – for incoming calls.

I have not managed to do it (neither for incoming nor for outgoing calls).

In ./conf/dialplan/default.xml,  <extension> section, I added :

<action application="set" data="sip_h_User-to-User=123"/>

or

<action application="set"><![CDATA[sip_h_User-to-User=${sip_Call_ID};tenant=1101;DID=${sip_to_user}]]></action>

No result.

In sofia_presence.c, I’ve seen some code for "User-to-User", so it should be possible. But how to do it ?

Best regards,

Adrian.
