Hello, I am having an ongoing issue getting a Customers Polycom VX3000? to work via a BRi Card on a Rack, this connects to the SX2000 BRi card, and talks to the SX2000 via DPNSS... Anyway, calls go out ok, ring the other end, but negotiation and call setup doesn't happen, it could be the VC unit, as I have tried replacement cards, default database, then re-programme. All I have prog'd is the Local address, and CLi info, your help appreciated, card is setup for ETSI and LT mode. SX2000 is on LW34.
