Thank you. Is this valid also from a conversion from rtp-nte to h245-alp ?
That is the case: CME Phone----sccp--->CME---h323(h245-alp)--->IPIPGW-----SIP(rte-nte)---->CM-----sccp--->Unity Date: Thu, 2 Apr 2009 18:13:49 -0700 From: anil...@yahoo.com Subject: Re: [OSL | CCIE_Voice] DTMF digits from CME calls to Unity does not work To: ccie_voice@onlinestudylist.com; spoli...@hotmail.com I believe it will not work since the conversion of dtmf digits from h245-a to rtp-nte is not supported on Cisco SIP trunk side. --- On Fri, 4/3/09, Sergio Polizer <spoli...@hotmail.com> wrote: From: Sergio Polizer <spoli...@hotmail.com> Subject: [OSL | CCIE_Voice] DTMF digits from CME calls to Unity does not work To: ccie_voice@onlinestudylist.com Date: Friday, April 3, 2009, 5:38 AM Hi, I'm trying to make DTMF digits be recognize by Unity from CME calls through a IPIPGW.
