HDX SIP registering to MITEL NCD 4.0ST3

[petet]

I've registered our HDX7k to Asterix SIP & that works just fine as an Analogue SIP call to PSTN or internal extensions.

We have acustomer with an HDX estate and a MITEL NCD 4.0ST3 switch.  Is there anything out there that could translate Polycom HDX SIP signalling to Mitel?

Mitel is using own SIP-based proprietary protocol. SIP is the only way to communicate.

Sorry. Mis-information in the original post. MCD 4.0 & 4.1 are in the IP5/6/7 Inter-Op Compatibility lists but your post on Mitel generally supports my view that mostly their SIP isn't SIP.
