[OpenSIPS-Users] How to identify the Requst was generated by B2B scenario

[Anca Vamanu]

Hi Antonio,

You can catch the B2B generated INVITEs in local route. Probably you 
don't have any other generated Invites, so there is no need to filter 
them. But if you do, a good solution is to use at the Contact header. It 
must contain what you set in the "b2b_entities" module parameter 
"server_address".

Regards,
