VVX Phones MWI Subscribe

Hello Community, 

 

We have been upgrading the SoundPoints in our environment to VVXs recently. As we have been doing this we have noticed that the traffic to our Voicemail service for MWI subscriptions has dramatically increased.

The VVXs are sending Subscribe messages every 30 seconds. We have set all the settings documented like 

voIpProt.server.1.subscribe.expires="3600"

We also see the Subscribe with an expire of 3600, but the phones are still sending at 30 second intervals. 

Anyone else notice this?

Just seeing if the community had options we have overlooked or if anyone else is seeing this.

 

Thanks

Re: VVX Phones MWI Subscribe

Hello CDE,

welcome back to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here

 

I suggest as well to post a backup of your configuration so we can double check that you have actually included the configuration you are trying to add.


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Re: VVX Phones MWI Subscribe

Sorry I didn't include the firmware details. 

 

We have a bunch using 5.2.0 and a few using  5.5.3 firmware. 

 

We have also tested one phone with variations of the firmware between and still see the Subscribe messages being sent every 30 seconds. 

Also, we are seeing this not just with the MWI Subscribes but also with all Subscribe events. 

 

Thanks

Re: VVX Phones MWI Subscribe

Hello CDE,

As you still have not attached a backup please get this into support via your reseller.


In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you. End Customers are usually unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Re: VVX Phones MWI Subscribe

Hi,

 

Any updates on this issue?

 

We're experiencing the same problem.  30 second subscribes, despite what the configuration is set to.  With hundreds of phones doing this, we're seeing 300 SUBSCRIBE messages per second and we're needlessly increasing load on our system to the point that we're occasionally overloaded and we need to block SUBSCRIBE messages at our firewall to reduce the load.

Hello @intellasoft ,

 

welcome to the Polycom Community.

Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.

This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.

As a reminder the basic information asked for:

 

  • Provide the exact Software Version of your Phone
  • Provide the Phone Model
  • Provide the Call Platform (aka openSIP,Skype for Business Online, Skype for Business on Premise, Lync)
  • Additional Polycom Infrastructure (RPRM,PDMS or BToE)
  • If applicable provide a backup of the phone in question

UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup. Please rename into .TXT or Zip the file to attach.
Since UC Software 5.9.0 simply provide this via the Web Interface Diagnostics > Download Support Information Package

  • If possible provide a Log and either attach them or use the Code Tag.Consult the Troubleshooting Section found within the FAQ if applicable
  • If possible provide the MAC Address or Serial of the device
  • Provide details for example if the issue is a day 1 issue or only happened after an upgrade or any other relevant details
  • For questions around Support please check here

 

Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Polycom to have an overview of the current software used. In addition providing all details at the same time allow us to check logs or look up a potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.

 

As you responded to a post from 2017 I would assume that the user since then has contacted our support team so we could check for the Root Cause.

 

I suggest you do the same to safe yourself some time.

 

End Customers are unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter providing your MAC address or your Polycom devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Polycom device from.

If the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier

Version: 5.9.1.0615
Model: VVX-411
Platform: Asterisk 11, Asterisk 13, Asterisk 16
Mac: 0004f2680175
Support File: Attached

 

Two SUBSCRIBE messages (one unauthenticated, one authenticated) are coming from each phone, for each subscribed item, every 10 seconds. 

 

Across 600 phones this results in a DENIAL OF SERVICE to the pbx.  We have to implement rate-limiting of SUBSCRIBE messages using iptables to avoid a denial of service caused by the unreasonble 10 second SUBSCRIBE.  We need to be able to set the phone to only try SUBSCRIBES once per 300 seconds or more.

Re: VVX Phones MWI Subscribe

Hello @intellasoft ,

 

The MAC you provided was sold via Scansource back in 05/03/2014 so the question would be if this has always been an issue ?

 

We would need to see a full Log with SIP at debug but this may be outside of the support I can provide for free within the community.

 

I suggest to look at the Server side and the expiration time returned by server.

 

If this all fails and nobody else has a comment the next step would be to open a ticket.


In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

End Customers are unable to open a ticket directly with Polycom support.

As the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
