I have a client who acquired a site with an NEC SV8100 and currently has about 5 sites on IPOffice that he wants to be able to link to the NEC. I saw this post but it looked like they were doing it locally through a local trunk. Does anyone have any experience connecting these 2 types of systems via a QSIG H.323 or SIP trunk that can give me direction? The vendor that maintains the NEC mentioned using CCIS, but as far as I can tell this is a proprietary NEC format.

You will need to use SIP for this, the IP Office side is a doddle if your even half competent. The issue is how well he knows SIP on the NEC

CCIS also appears to be ISDN based, much like Qsig. So useless anyway unless they are co located NEC systems

Hi did try this a few years ago but ran into issues using SIP it because the NEC uses two IP addresses one(IPLA card) for call setup and one(Virtual Gateway) for RTP this was on the same LAN
I could call from the IP office to the NEC and the phone would ring with the correct display info but when you answered no speech was heard
I could not dial from the NEC to the IP office
This is as far as I got as this was just playing about in the office
Let me know if you get it fixed
