help!TX1310 P2P transmit at 1.87M(720P)

huang-leon · ‎06-01-2013

Hi everybody,

we have two TX1310 (1.9.6) and registed to cucm (9.0.1) successfully.We can now use touch 12 to make a call to each other.But it appears only 720P at 1.87M.

So we make a call from TX1310 to our TP 7010 MCU with SIP truck from VCS C,it appears call rate is 4M 1080P.Great!

We have check the CUCM Device---Phone setting,set the TX1310 at 1080P best motion.And CUCM location(Hub as default) is set to no limited.Is there any configuration will be affected with the transmit bandwith for TX1310?

BTW,network enviorment is 10M MPLS ,no bandwith limited.

Check your region settings - the device pool that your TX1310s are part of will have a region associated with them. Check that region's settings - it will have a maximum video bandwidth setting to both itself and other regions.

If your MCU is in a different device pool and region to the TX1310s, this could be why the bandwidth is limited.

Hi Nick,

this session we do have not check.we will make the setting correct tomorrow afternoon and check it out.Thanks a lot!

BTW the TP MCU is registered on VCS control,not a part of CUCM...TP MCU works just through sip truck from vcs to cucm.how does it explane the 4M 1080P from TX1310 to MCU? The region on CUCM does not has bandwith restriction to truck? Or it works with Location settings?My confuse

Each region has a setting to define how much bandwidth to use to each other region as well as how much bandwidth to use to other endpoints/trunks in the same region.

In your case, the SIP trunk to VCS is likely to be part of a different region than the TX1310s are part of. The TX1310 region is probably allowed to use 4Mb/s or more to the SIP trunk region, but only 2Mbps to other endpoints in the same region.

Also, don't forget - endpoints and SIP trunks get their region from their device pool, NOT their location settings. You will need to go to System > Device pool to see which device pool uses which region.
