Custom SIP Headers

is it possible to have a custom sip Headers in a tenant trunk

onder the tap advanced

Can anyone please help

Yes, that is exactly what the section is for. As an example I use the X-Tenant header on the outbound trunks to define which tenant is making the calls so that my trunk provider can properly track usage.

Yes but I can only set it in the main trunk I

want to be able to set it in the tenant trunk

If I create a tenant trunk option advance is empty

It does not seem like it is possible at the moment. You can request this feature under #wish-list

Anyway, you can set the headers on the parent Trunk using a variable set on the tenant level.
