Hi, Using Asterisk 1.6.2.13 We are now starting to use *call transfer (patching) function.* Call flow is as follows: ----------------------- John Calls me and requests him to be connected to Nancy. I place John's call on Hold I dial Nancy and speak with her about John I then patch the call between John and Nancy My line is free for the next call while John & Nancy continue their conversation In this scenario, my conversation with John & Nancy is perfect. No problems. But both John & Nancy report that the conversation between them (after I patched them) has a lag of about 4-5 seconds. I am not able to understand why this is happening. I am using GrandStream GXP280 IP Phone. Pls suggest what may be the problem area and how should I resolve this. Thank you. Best regards, Sans -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-users/attachments/20111004/17c42bf6/attachment.htm>
