Yes, I do. It is transcoding the differents codecs from this call. A simple hold/unhold works also. The only problem is related to the DTMF. When I call to the Unity from CME phone It does not "understand" the DTMF digits.

This sounds like an issue where you may be having a supplementary services problem. If I'm right, you probably can't hold and unhold the call either. ----- Original Message ----- From: Sergio Polizer To: ccie_voice@onlinestudylist.com Sent: Thursday, April 02, 2009 8:08 PM Subject: [OSL | CCIE_Voice] DTMF digits from CME calls to Unity does not work Hi, I'm trying to make DTMF digits be recognize by Unity from CME calls through a IPIPGW.
