SIP & Microsoft Lync

[racebikeboy]

We have System & Session Manager with ACM 5.2.1 can anyone help

Lync call forwarding / simultaneous ring does not work
Call originates from Avaya (internal extn or PSTN) to Lync dummy 45xxx extn (via Avaya DDI using EC500) -> Lync call forward or simultaneous ring configured to mobile or other Avaya extn and the call will not complete. Originator just receives ringing tone and Lync user does not receive any inbound call notification

Calls sometimes hang on the Net UX2000
This is not priority by any means but we get occasional calls that do not clear down the NET UX2000 gateways so channels are unavailable until a reboot of the UX to clear.

Avaya continues to ring when unanswered
Lync calls Avaya extn, call goes unanswered so Lync user terminates the call -> results in Avaya extn continuing to ring for a period of approx 1-2 minutes.

Are you using extension numbers in LYNC to get the call forwarded?
I've found that you can not use extension numbers...because LYNC is a separate server, it has to dial out to those forwarded locations using your Avaya system resources. So your entries have to have a full phone number in it...not just a 3, 4, or 5 digit extension number.

On the trunks in question... SIP or otherwise try adjusting the Send Diversion Header option from N to Y or reverse.

Thanks,
