[OpenSIPS-Devel] Get Dialog from callid or h_entry/h_id

[Daniel Zanutti]

Actually I did register to receive the dialog callback and it's working
fine.

The problem happens when I receive a 200 OK of the Invite, simultaneously
with BYE. On BYE i delete the call from my controls, then process the 200
OK, dialog has all info of the call and I load it back. I'm not sure if
it's a bug but the fact is that I need to check if dialog still exist.

Will it embarrass so much the system to return a different positive value?
