Hello to everyone in the community. This is my first time posting here. Please excuse my ignorance and lack of telephony experience.

 

Bottom line, I don't know if this is a phone configuration issue or a PBX issue.

 

I am coming here to humbly ask for your help. I work for a private (low income) school as their do-it-all IT support person. This summer I have been tasked with installing a new intercom system throughout the campus. I decided IP phones would work well and be future proofed to eventually provide public telephone service in all rooms.

 

As a private school we were given a donation of 65 Polycom phones from the local public school district as they had recently upgraded. We received VVX400, VVX401, VVX410 and a few VVX411.

 

Upon receiving the phones in various states, I cleaned, reset and upgraded all of them.

 

The phones and PBX are on a local area network, I choose to statically assign each IP address. Initially I tried using FusionPBX as the local PBX software onsite and connected the phones with the SIP registration. I did not use any auto-provisioning features on the server side. I created a configuration text file and used the https web portal to uploaded it to each phone with a few minor changes for extension/name.

 

Here's the problem. As the title states, when certain extensions are dialed all (every single one) of the phones will display a message on screen that says "Incoming call To: ext#(ext name) From: ext #(ext name)". After a few seconds the message on screen changes to a smaller box that says "Remote: Tech Coordinator To: ext#(ext name) From: ext#(ext name)" This alert message does not produce any audible tones, except at the actual extension that was dialed the phone rings like normal. The call can be answered only from the extension actually dialed. Roughly half of the phones exhibit this problem. The problem seems to come from the extension being dialed rather than the one doing the dialing.

 

After experiencing this problem I tried switching to a different PBX software. I installed FreePBX and tried again with the exact same results. The exact same extensions were the problematic ones. If I changed the phone extension and sip server extension from let's say 200 to 199 it worked fine. 

 

I have spent many days researching and learning and I don't know what else to do, school starts in 2 weeks. After trying two different software servers I figured it must be the phones?

 

Not sure if this helps but extensions that don't work include 100,200,228-239 excluding 233. Extensions that work fine include 99,101,201-227, 233. I don't see much of a pattern. There appears to be no correlation between phone models and the problem extensions. All phone models work and don't work equally.

 

Some information about the phones:

VVX400 all upgraded to 5.9.7.3480

VVX410 all upgraded to 5.9.7.3480

VVX411 all upgraded to 6.4.3.5156

 

This is an example of the configuration I was sending to the phones.

I have attached logs and backup files from both a good and bad extension.

The MAC from ext202 is 0004285c38c  and MAC ext229 is 0004f27f6ee1

 

If there is anything else you need that would help you please feel free to let me know.

 

Thank you in advance, your thoughts and experience will be much appreciated!

I just wanted to follow up on this thread and let you know that I found the solution.

 

		attendant.behaviors.display.spontaneousCallAppearances.normal="0"

 

That parameter was the one I needed to turn off the Directed Call Pickup feature on all phones. Still not sure why it was only enabled on some. I thought by default its supposed to be off.

Hello @Victor_E ,

 

Welcome to the Poly Community.

You are basically using BLF/Busy Lamp Field

 

This means other phones are alerted when a phone that monitors another line is being called.

 

As this is not a shared line it will only ring once and then visually alert.

 

Details are here:

 

Nov 4, 2011 Question: How can I set up a Busy Lamp Field / BLF with a Digium Asterisk SIP Server?

Resolution: Please check => here <=

 

There are prerequisites in order to be able to pick up another call from a BLF as outlined in the attached FAQ.

 

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

Best Regards

Steffen Baier

Steffen,

 

Thank you for the quick reply. Your answer has helped me to understand why some of these phones exhibit this behavior but not others.

 

I thought it was a problem, but now I understand its a feature.

 

This feature is not needed or wanted in this installation. I have done some reading about Directed Call Pickup. To turn this feature off some of the community members suggested this:

___________________________________

While there isn't an explicit parameter to disable directed call pickup, we've found that we can achieve this with the following parameters:

 

call.directedCallPickupMethod = legacy (this is the default)

call.directedCallPickupString=""

 

With call.directedCallPickupString set to an empty string, the phone will simply dial the extension associated with a BLF without dialing any star sequence first. Thus, the phone doesn't initiate a directed call pickup, but simply dials the extension associated with the BLF. This is exactly the behavior we wanted.

___________________________________________

 

And this:

________________________________________

attendant.behaviors.display.spontaneousCallAppearances.normal="0"

 

did the trick. Default value is "1".

____________________________________________

 

Do those parameters sound correct?
