DSPs would be installed in a router (e.g. a 28xx or 29xx, or any other decent ISR).</P><P></P><P>2) Yes, CUCM only conferences g711 with the software conference bridge. For G729 conferencing, you would have DSPs in an ISR and either transcode the streams that go to the CCM software bridge, or simply conference on the DSPs directly.</P><P></P><P>Aaron</P><P></P><P>Please rate helpful posts...</P></BODY></HTML> Tue, 13 Sep 2011 09:57:55 GMT https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796762#M62860 Aaron Harrison 2011-09-13T09:57:55Z Onboard DSP in CUCM MCS server ! https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796763#M62861 <HTML><HEAD></HEAD><BODY><P>Sir, </P><P></P><P>I tried this in lab using CIPC and IP blue phones. I assigned HO device pool and set G.729 codec between each other. Now when i try to do conferencing, the calls are made (i cant actually speak anything since there are no mics), so why the conference call went successful when CUCM only support g.711 conference ?</P><P></P><P>Kindly guide me </P></BODY></HTML> Tue, 13 Sep 2011 13:57:11 GMT https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796763#M62861 Jonn cos 2011-09-13T13:57:11Z Onboard DSP in CUCM MCS server ! https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796764#M62862 <HTML><HEAD></HEAD><BODY><P>Hi John</P><P></P><P>When you have the conference running, have you verified the codec in use by hitting ? twice on the CIPC?</P><P></P><P>Aaron</P></BODY></HTML> Tue, 13 Sep 2011 15:06:33 GMT https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796764#M62862 Aaron Harrison 2011-09-13T15:06:33Z Onboard DSP in CUCM MCS server ! https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796765#M62863 <HTML><HEAD></HEAD><BODY><P>yes sir i checked. when i make a simple call, its showing me G.711 codec !!!</P><P></P><P>Why is that so when i set the region to select g.729 even when they are calling each other !!</P><P></P><P>Pls tell me whats happening here</P></BODY></HTML> Tue, 13 Sep 2011 15:35:19 GMT https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796765#M62863 Jonn cos 2011-09-13T15:35:19Z Onboard DSP in CUCM MCS server ! https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796766#M62864 <HTML><HEAD></HEAD><BODY><P> The plot thickens...</P><P></P><P>So - you have created a region?</P><P></P><P>You need two regions.</P><P></P><P>Each region must be assigned to an individual device pool.</P><P></P><P>One phone must be in each device pool for this test.</P><P></P><P>You must also verify that the region matrix is configured correctly - i.e. the codec selected between Region1 and Region2 is g729.</P><P></P><P>Aaron</P></BODY></HTML> Tue, 13 Sep 2011 15:39:28 GMT https://community.cisco.com/t5/unified-communications-infrastructure/onboard-dsp-in-cucm-mcs-server/m-p/1796766#M62864 Aaron Harrison 2011-09-13T15:39:28Z
