Hello all,
We have two DX650, one in HO (local to CUCM) and one in remote site (over MPLS WAN).
When Dx650 from HO call to DX650 in remote site DX650, DX650 rings but is not able to press answer key. When press Answer key nothing happened and phone keeps ringing. Tried vice versa call (from DX650 remote to DX650 HO) it goes successful.
There are 7821 phones in remote site as well. Call from DX650 (HO) to 7821 is successful without any problem & vice versa call is also successful
Any advise to troubleshoot ?
Call Manager is version 11.0 and DX650 has latest firmware (cmterm-dx650.10-2-5-212.k3.cop.sgn)
HO and Remote site has different Device Pool and Region.

Hi,
Can you look at SIP messages for remote DX and see if any message is being sent when you hit enter.?
Also, try to call from deskphone @HQ to DX @ remote and see if it works.

Hello,
When I disabled video on DX650 the call is working fine.
I believe it is due to the video bandwidth in region.
Region is defined as default video settings
Max Session Rate for Video = "Use System Default (384 kbps)"
How to make it work with video enable ? How to setup unlimited video bandwidth for call ?

Yes both are in different regions but I found same problem among phones in same site (same region).
When I disable video calls from Device->Phone it works fine.
What is recommended bandwidth ?

Just verified that video & audio bandwidth is set as " Unlimited " under Location section as Hub_None.
And phones are configured with Hub_None Location.
Any suggestion for fix ?

So the way it works is when you pick a region from the previous page, for example here "GDUP-R", you are choosing what region-to-region setting
So in the list below the "modify relationships" pick the region that contains the second dx video device, then modify the

Try increasing the bandwidth there because the default 384 is not enough.
Although this is probably not the issue you are experiencing.
