Looking for an explanation as to why one method works over another.
VTA 2.x client (near the latest)
MPLS, with 256k voice, >=384k video
Two locations, each with own cluster
Locations on each cluster set to same bandwidth.
Using ICT (non-GK)
One phone on each cluster place video call to each other. Works for a day or so. Call finally fails due to lack of bandwidth. Resync's and changes to bandwidth, including unlimited, prove futile.
After video call and changes fail....
Take phone from one location\cluster, and register it to the other location\cluster. Bandwidth therefore is "unlimited".
Video call works flawlessly, and will continue to work flawlessly.
This is not a bandwidth issue. Same pipe, same routes, same equipment, etc.
In the past, many issues we've had with this could be attributed to our firewall configs.
But I'm not convinced anymore. Something seems wrong with CCM's bandwidth calc logic.
Supposedly TAC emulated our setup in lab environ with 4.1.3sr7 (engineering only ??) and got similar results, but we never got a resolution.
Anyone have some insight on this ?
