Sample configuration for Video Conference Call through CUBE

Here is the Sample configuration for Video Conference Call through CUBE voice-card 0  voice-service dsp-reservation 50 ====> dsp needs to be reserved for VOIP calls and TDM video calls, %age of dsps. Unreserved DSPs can be used for IP video. If you reserve no DSPs for VOIP calls, you'll not be able to add video as it needs VOIP audio. There will be no way to even add the codecs. ! dspfarm profile 2 conference video homogeneous  codec ilbc  codec g711ulaw  codec g711alaw  codec g729ar8  codec g729abr8  codec g729r8  codec g729br8 ====> all the audio codec will be added by default  codec h264 cif frame-rate 30 bitrate 320kbps ===> all participants will be forced to use same codec, same framerate and bitrate, if negotiation fails, call fallback to audio only. Hetergenous mode- participants can use their own codec/bit/frame rate and multiple video codecs can be added however, it requires more PVDM3 resources as it reserves the dsps for video conference.  maximu

In order to enable video capabilities on the phone, you should have "video capabilities" field as enabled on the phone's configuration page. There is no other configuration required on CUCM and gateways.

SIP Phone Registeration on CME

voice service voip sip ===> enables SIP on the router registrar server ===> Accepts registration requests ! voice register global  mode cme  source-address <ip address of cme router> port 5060 ===> IP address through which Phones will communicate with CME  max-dn 10 ===> count of DNs that can be added  max-pool 1 ===> count of pool of either a single IP phone or group of phones. ! voice register dn  1 ===> where you create the number to assign on Phones  number 4002 ! voice register pool  1  id mac 580A.2099.3F37 ===> using the pool to create a single IP Phone pool  type 9971 ===> defining type is as important as defining the mac-address  number 1 dn 1 ! voice register global create profile ===> similar to create cnf-files, this will create the phone profile. ! end

Important Service Parameters in CUCM

" always use transformation for remote party" Cisco IP Phones do not understand the transformation patterns even though you have applied its CSS in their device pool. This parameter should be enabled so that Phones start to take the applied transformation patterns. This parameter is efficient in a global dial plan to normalize the calling number displayed on the IP Phone. "always display the original dialed number" As the name suggests, this parameter is used to display the original dialed number on the IP Phones, even though the appending digits or dialing code gets stripped.
