[Freeswitch-users] Fwd: Originating a call between an user and mod_httapi-based IVR service - passing some correlation ID

[Michael Collins]

I think in the cookbook we cover the use of the create_uuid API when doing
an originate. You pre-generate a UUID and then it is available to whatever
processes you have running. Once you have the uuid then you use
originate_uuid=<uuid_value> in the dialstring.
