SIP MWI

SIP MWI

(OP)
We are in the process of having a new 3rd party VM system installed. System is online and we are able to cover to it. our CM is a 6.0.1 and have SIP (TLS) trunks to ASM and the VM system is an entity link of ASM via SIP (TCP). Our phones are 9630 H.323. We are able to cover to a test mailbox, but the MWI is not working. Seems like it is failing when it hits CM on the comeback with 501 not implemented. Any clues on what can be missing in CM.. the station is set as SIP-ADJ on page 2 to match the HG.

RE: SIP MWI

What would a traceSM show you? You ought to see a NOTIFY from voicemail to SM and then SM to CM. SIP domain from the VM has to match the far end signalling group, mailbox and extension numbers ought to line up. Is your voicemail sending SIP notifies through SM to CM, or directly to CM? I would think the former would be required. MWI type sip-adjunct, basic stuff like that.

501 Not Implemented

The server does not support the functionality required to fulfill the
request. This is the appropriate response when a UAS does not
recognize the request method and is not capable of supporting it for
any user.


I would verify configuration in your 3rd party VM system Solution

What system is it ? They should be able to pin point it.

turned out Session Manager didn't have the CM as the destination entity for the return traffic from the VM system. It was sorted.. thanks again guys.
