[SR-Users] Dialog using Recod Route, with an asterisk

[Daniel-Constantin Mierla]

Hello,

Asterisk is a b2bua and it is normal to create a completely new and
different call. It is not only the missing of the record-route, but
different call-id, from-tag, etc ... Also, Asterisk can create many
outbound calls out of one incoming, for example in case of group hunting.

If you want to track a single dialog in such case, you have to track
only incoming one to asterisk, or the outgoing one.

Cheers,
Daniel
