Concurrent Telephone calls with an SX20

[Chris Jansen van Rensburg]

Hi All

We have a client that has an SX20 with ISDN link and Multisite loaded.  There are 4 x BRI ISDN lines active and installed.   Does anyone know how many concurrent telephone calls the unit will support.  I know the theory says its 64k per call which should equal 8 calls .... but has anyone tested this before? 

Thanks!

Sx20 can support 3 other video calls and 1 addtional audio calls, so you are still limited by that.

Have you tried looking at a hosted solution for your client. That may be another viable option.

Hi Chris,

The SX 20 has a capability of 1 video + 1 audio call (if multi-site option is not installed)

If multi-site option is installed, SX20 has capability of 3 video + 1 audio call.

Hi Chris,

You can check the capability of the maximum number of audio and video calls in the xstatus.
