[OpenSIPS-Users] shared memory on opensips

[Bogdan-Andrei Iancu]

Hi Sam,

first you make kind a confusion between a call and a transaction. A 
transaction is one request + all its replies . A call is a set of 
transactions (for creating, changing and terminating a SIP session / call).

Now, opensips (if not using dialog module) is not dialog aware - it does 
not know what transaction belong to what call. Because of this (there is 
no call state), a restart during a call will not affect the ongoing calls.

On the other hand, the transactions (for INVITEs, BYEs, etc) are not 
persistent during restarts.

Regards,
Bogdan
