| I just received a confirmation from the customer. They have a NEC2000 in NY. A NEC2000 in WI that are using CCIS (NEC private protocol). The NEC2000 in WI is connected to the Nortel PBX via PRI.
2500>Nec2000 NY>CCIS>Nec2000 WI>PRI>Nortel SIP>Meetme.
The NEC manual states that CCIS is orginal protocol. We also have the same issues on carrier VoIP. |
