Hello,

I have a test C++ SIP application that registers to a Lync edge server and is able to perform MRAS requests to it.

The MRAS responses allow me to create TURN allocations on the TURN component of the edge server. However, I seem to be hitting a limit with the number of simultaneous TURN allocations I can create with a single registration.  I seem to be able to create a maximum of 50 TURN allocations for that single registration.

Is this a configurable option - either per user / per edge server etc - for the maximum number of TURN allocations a single Lync user can simultaneously have?  Or is there anything else I can put in the SIP/TURN signalling to increase this limit?

Many thanks,

Simon

Hi,

You may need to custom your own Lync server, so you might post the issue on Lync MSDN forum and more developing expert will help to verify the information using Lync SDK. Thank you for your understanding.
