Thank you for your reply.  Sorry for leaving out important details.

exten => _XXX.,n,dial(iax2/hkiaxtk/9${EXTEN})
exten => _XXX.,n,hangup
{noformat}

if you need some iax configuration or others, I will post later.

2. The behavior we expected
  The monitor application will generate two files, one for inbound channel named as "*-in.wav" and the other for outbound name as "*-out.wav". For the real-time conversation is okay, when we play the monitored two files at the same time, we expect they can represent the conversation as it was.

3. The behavior we encountered
  When we played the monitored two files at the same time, occasionally they were not synchronous. It seems that the outbound file has some segment lost and since that lost part it is ahead of time relative to the inbound file. For example, the one (inbound) have not asked a question, the other one answered. And in my experience if the problem occurred, at most time the call conversation was long.

If some other information is needed, I will follow up as quickly as I can.

> When using monitor application to monitor conversations, the monitored two files, "*-in.wav" and "*-out.wav", are out of sync occasionally. The file '*-in.wav' is okay, but the monitored file '*-out.wav' has some segment lost.
