HI Stewart,
Appriciated for your kind of explination to solve my problem.
Yesterday i spent whole days to capturing and tracing the packets. and i found there is some problem in oh323 channel itself. Because the problem is only happening when i am dialing OH323 to OH323. But when i am tring to dial from OH323 to SIP it is working well.
Still i am searching in OH323 channel what is the problem.
