The issue we are facing right now with the We conducted a series of off-network tests yesterday and our unit xx.xx. xxx .100 cannot succeffully place calls from the SX20 unit itself. Using the web interface there was no problem.
With the exception of the SIP ports, all other ports are open.
But that should not be a show stopper,its either SIP or H.323.
What configuration on the units need to be entered based on the current static ip setup(since we are not using a management server for provisioning).
