Using PVDM3 for Video Switching - CME

My environment:  IOS 15.1(4)M, CME 8.6 on 3945

The configuration of video switching DSP farm is similar to the voice conference DSP farm.  There are 2 different types of video conference, homogenous and heterogenous.  For homogenous, assuming the video codec and resolution for endpoints are the same.  For heterogenous, you can have different endpoints with different video codec and resolution.  In this post, I am trying to use 9971, 9951 with unified camera in a CME-only environment.

Since DSP farm can only registered to SCCP CME or UCM, telephony-service configuration needs to be done to allow the video conferencing dspfarm registered to it.  You need AT LEAST ONE SCCP PHONE to initiate the conference ad-hoc or meet-me conference.

1.  voice-card 0 configuration, the new dsp-reservation command reserves a certain portion of DSP for voice.  dsp-reservation 0 means all DSP will be used for video.

voice-card 0

 voice-service dsp-reservation 0

 dsp services dspfarm

2. voice-service voip configuration, allow sip and h323 interwork and enable sip registrar

voice service voip

 allow-connections h323 to h323

 allow-connections h323 to sip

 allow-connections sip to h323

 allow-connections sip to sip

 fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none

 sip

  registrar server

3. SIP CME configuration, remember to enable unified camera and video, either globally or per phone.

6. Create ephone-template and apply it to the ephone who wants to initiate meetme conference

7.  Create ad-hoc video and meetme video ephone-dn

8.  Try to initiate a meetme video conference from the SCCP phone, the let the 9971 phones call in the meetme number.  It will work.  I don't have enough PVDM3 for heterogenous video conference therefore I didn't try the ad-hoc video conference, if you have tried it and it works, feel free to share with me your result.  :)
