[Asterisk-video] IP Camera to Asterisk Interface

Thu Feb 22 10:18:17 MST 2007

As far as I know Cisco 7985 supports only SCCP signal protocol (not SIP) and
doesn't support h.262 only H.261, H.263, H.263+, and H.264

If your cams don't support one of these codecs, you need use
enconding/decoding or other phones with h.262 support
