Ive not tested with OCS so i cant vouch if it will work or wont,
but i know the BCM 50 400 and new 450 wont work with exchange Um due to the fact they cant deliver the relevant divert Info.
We are currently working with the BCM 50 and utilized the DTMF but this also doesnt send out the right information.
the new release 3.0 software for the 50s now does DTMF over SIP, of which we have yet to test for Nortel.
please see extract from my contact
'im afraid the BCM 50 is, currently, actually more functional than the BCM 400 : - )
We have the BCM 450 about to be released that bridges the gap somewhat, but the product range doesn't support OCS or Exchange - and I'm afraid it won't (its not in development either). This is something that the CS1000 will continue to do.
Hope i helped
regards
Robert
