[cisco-voip] Does 12.4(11)T now do H.323 to H.320

[Patrick Mowry]

My junk mail filters have been eating mailing list messages lately, so
forgive me if me response is late.

Your PRI provider has to accept a Bearer capability set to Data for
video calls to work.  Most of the time it is not an issue, but I did
have to make a change request on a BellSouth line once for video to
work.

As for the IOS feature, my understanding is the conversion feature works
well, but the bonding of channels together is currently limited to 2
channels (128K video calls) but will grow to support 384K calls soon.

  It is a good thing to play with and worth while to test with Polycom
and VT Advantage endpoints.  But if you need 384K for business use you
would still need an IP/VC gateway for now.

There's a feature in 12.4(11)T described in 
http://www.cisco.com/en/US/customer/products/ps6441/products_feature_gui
de09186a0080788070.html

"The Integrated Data, Voice, and Video Services for ISDN Interfaces 
feature allows multimedia communications between H.320 endpoints and 
H.323 or Skinny Client Control Protocol (SCCP) endpoints."

In reading it a few times, I'm still trying to understand if it means 
that I can now have a H.323 Polycom EX make and receive calls on a 2851 
router that has a standard voice PRI or do I still need to get an IP/VC 
box.

Also, the examples are terrible.  There's no diagram, there's no 
explanation of what session targets are connnected to, etc.  This is a 
fairly recent IOS, so I'm not sure if I'm blazing a trail here...
