Does ANYONE know if CCIS v10.50 compatible with older CCIS? I plan on really digging into this but frankly I don't think even NEC knows or cares. I plan on a MUCH more robust test when I get back from my vacation but right now it doesn't look like it is.

Thanks

I copied this from the V10 Feature Manual. Assuming this is K-CCIS-IP...

Description
The system uses the GPZ-IPLE daughter board to connect multiple systems together over a Data Communication IP Network (Intranet). Key-Common Channel Interoffice Signaling (KCCIS) is used to provide telephony services between the UNIVERGE SV9100 and another UNIVERGE SV9100 or a NEAX PBX system.

CCIS Networking via IP (Non Peer to Peer Connections Basis).
? IP trunk connections over CCIS Networking via IP provide telephony services between UNIVERGE SV9100 and UNIVERGE SV9100 and a NEAX IPS, IPX, SV7000, UNIVERGE SV8100, UNIVERGE SV8300 and UNIVERGE SV8500.
? The UNIVERGE SV9100 uses the NEC proprietary CCIS Peer to Peer protocol over IP to communicate between system to system.

Ya, I know this. Pretty sure it does not work properly or at all right now. I am going to roll back the software level on a 9100 to see if this is the case.

on older versions it works. I have a client that has 1 9100 and it talks to 3 8100's fine.
