[SR-Users] RTPEngine and dialog moving.

[Vitalii Aleksandrov]

Hi,

Kamailio's rtpengine module has an internal hash table with call-id as a 
key and when you call rtpengine_manage()/_offer()/_answer()/_delete() 
kamailio finds corresponding rtpengine instance to send command to. So 
it's inside rtpengine module and not in tm or dialog and thus unlikely 
to be replicated. At least I haven't seen any replication code when 
checked it last time.
