[OpenSIPStack] FW: FW: OpenSBC as Forking Proxy

[Gustavo C. <cur...@ho...>]

Joegen,
=20
I tried the DoDNSFailover's code but i have the following behavior:
=20
When DoDNSFailover() is called for the first time m_FailOverAttempts is inc=
reased from 0 to 1.
=20
Then the via is changed (+ "-") and with this change when FindTransactionAn=
dAddEvent() is called a new transaction is created.=20
In SIPTransaction::SIPTransaction() m_FailOverAttempts is initialized to 0.=
 Then when DoDNSFailover() is called again, the same target is used.
=20
