Plantronics + Polycom.
Now together as
I am doing configuration of a Polycom ISDN Gateway and facing very strange issue. Post Configuration PRIs status trun Green and after 10-20 Seconds it turned to red.
PRI has been tested successfully on Digium EPBX and PRI tester of DU. We bring back the same unit to our other office and same was tested with Etisalat line as well but result is same.
ISDN Config done for E1 Line as per below.
Area Code- 03 (Al Ain in UAE)
PRI Video Number- Define PRI Piolet Number
Outside line dialing prefix- None
Numbering plan- Tried both ISDN and unknown
PRI Line- E1
Switch Protocol- NET5/CTR4
As per DU/Etisalat CRC is off hence not enabled.
Config and status screenshot attached.
Please help with solution as this was raised with polycom and they did RMA for the same and RMAed unit is also having the same problem.
Any one installed New ISDN Gateway in Middle East, Specially in UAE.
