Transfer and IP-to-IP Direct Audio

[DICS]

Definity connected to IP Office using ip-trunk. In ip-network I have enabled audio hairpinning in ip-network-region.

I do following:

1. I make a call from Definity`s ip-phone to IPO`s station.
2. I make transfer from ip-phone 4602 to another Definity`s station.
3. Station rings but there is only silence instead of speech.

In another cases transfer works normal.

if it isn't too late - you should check up codec set in ip-network-region form, and if it is wan connection , you should have G.729 as a choice (on both side). it seems to me that you have signalling between two sites, but no voice communication, or...

No, problem is not in codecs. I have G.729 on both sides.
