[Kamran Ahmad]

hello

i need help on PSTN Calls via quintum gateway. i have
a simple problem when i am try to send INVITE to PSTN
quintum gw. it is replying me 183 session progress and
call duration is starting at this point. after this he
is sending ringing then 200 OK. Billseconds are
incorrect in this case.

4|<--(200)--|<---(200 ok)----------------|
5|--(ACK)-->|---(ack)------------------->|
