MWI on Polycom IP650

[Anonymous]

I cant get MWI on a Polycom IP650 to work. I see the Message Waiting=Yes in the debug. I am using a NV6355 connected to a Metaswitch. Any help is welcomed!

Just one phone or all at the site?  Could be the Meta, the NV6355, or the Polycom. 

Debug sip stack messages on the NV during a quiet time and leave a new voicemail for the user.  See if you are getting NOTIFY from the Meta and proxying it to the Polycom as well as an OK back from the Polycom passed back to the Meta.

I am testing this in a Lab environment. I only have 1 phone connected. Attached config and debug. Thanks!

I see a couple of problems.  It looks like the phone is on the data VLAN 10.10.10.x and not the voice VLAN 10.10.20.x.  Perhaps LLDP on the phone isn't configured? 

The NOTIFY is coming from the Meta but the Adtran isn't forwarding it to the phone.  Your Public access-class doesn't have "allow list self self" configured to allow the Adtran unit to process traffic from the Meta.  It has list SIP which is empty.  Curious that the INVITE is being handled OK. 

What is the output from "show sip proxy user" ?

You have the phone defined as a SIP user as well as transparent proxy enabled.  If the phones are registering through to the Meta and it is processing the calls you probably don't want to define them as SIP users.

Thanks Jay. Can we perhaps talk offline? I am at xxx-xxx-xxxx.

Probably better to open a support case with Adtran.  I'm just a customer like you.

Ok. Thanks for the input.

Mr. Marteeny,

I just wanted to follow up with you on this forum post.  I believe I worked on this with you over the phone and we found out we needed a configuration change. The main configuration change we needed was to add "ip sip proxy grammar proxy-id contact-user" in order for the unit to work properly with your softswitch, which I believe was a MetaSwitch.  I'm going to go ahead mark this as the correct answer to this post, but feel free to unmark it or add more details if you are still having any issues.

Thanks!

David
