[reSIProcate] 200 Ok retransmission issue

[Rajat Lala]

Hi,

 

I am using reciprocate 0.9.0 with wince. I face a problem of retransmission
in 200 OK for INVITE request. I observe that the retransmission of 200 ok
occurs in less than 500 ms that set initially. When send 200 Ok for the
first time, Timer is set to Timer::T1 (500ms). But after sending 200 OK for
INVITE timer times out in less than 500 ms and retransmit 200 OK. I just
want to know has any body faced the same problem of retransmission of 200 Ok
or any other packets?
