Does Cisco UCM 6.1 and NEC IPXR15 support MWI across QSIG trunk

[AntBan]

Hello,
I have integrated my NEC IPX2400 Release 15 with our other site which has a Cisco UCM 6.1 using QSIG trunks. All basic calls and extended features work, except MWI. We are trying to migrate all user from the NEC to the Unity VM hosted by the Cisco UCM. We are able to leave a meesage for the NEC phones and NEC users can hit their corresponding mailbox, but when a message is left for an NEC user there is no MWI light. The light does come ON for the Cisco users.

Has anyone successfully passed QSIG-MWI messages across between NEC IPX2400 and Cisco UCM

Thanks
AntBan

Not sure what version of IPX2400 but fo release 15:
Features not supported
•Q.SIG MWI- Message Waiting Indication (lamp ON, lamp OFF), the current NEC IPX 2400 North American Release 15 software does not support QSIG-MWI

The only way to do MWI that I know of with NEC is direct integration with Unity using TMIG units.
