Now together as
I'm using VSX 7000s(v126.96.36.199) and VSX 5000(v188.8.131.52) to make video conference call bewteen 2 cities,
For ISDN, they are worked.
But for IP, VSX 5000 will crash and restart both around 30s dial in and out.
It began to happen after I replace a new router (VSX 5000 site).
I have FIXED PORT on VSX 5000 and PAT on router.
Have any suggestion?
I would run a near-end loop diagnostic and see if the issue occurs there.
System -> Diagnostics -> Network -> Near-end loop
This essentially puts the codec into a call with itself. Let us know whether or not the issue occurs during this test. The result should help us to isolate the issue a little better.
