Call pickup on the VVX410



I am using a custom PBX setup with some Polycom devices. I don't know where the polycom devices were purchased. 


I am testing a Polycom VVX310 / 0004f28df096

Model : 3111-46161-001 Rev A

BootBlock :


UpdateTool :

Version :


Setup : 

I setup a BLF on the phone using: 

<attendant.resourceList attendant.resourceList.1.type="normal" attendant.resourceList.1.label="600" attendant.resourceList.1.address="600" attendant.resourceList.2.type="normal" attendant.resourceList.2.label="221 Joe" attendant.resourceList.2.address="221"/>


<call call.directedCallPickupMethod="legacy" call.directedCallPickupString="**"/>
<lineKey lineKey.3.category="BLF" lineKey.3.index="" lineKey.6.category="BLF" lineKey.6.index="" lineKey.1.category="Line" lineKey.1.index="1" lineKey.2.category="Line" lineKey.2.index="1" lineKey.4.category="Line" lineKey.4.index="1" lineKey.5.category="Line" lineKey.5.index="1">

The BLF works fine. If I press the button, when the watched resource is idle or on a call, it calls the extension, as expected.


The issue is that when the BLF is flashing ( early ), I press the button and it dials '**' :

U 2018/01/08 14:26:38.167778 ->
INVITE sip:**@ SIP/2.0.
Via: SIP/2.0/UDP;branch=z9hG4bK61932d4647F70685.
From: "Test Support" <sip:262@>;tag=47D6D3FA-7F3580D9.
To: <sip:**@>.

The NOTIFY with the appliciation/dialog-info+xml does not give the target callid :


<?xml version="1.0"?>
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="2"           state="full" entity="sip:221@">
  <dialog id="2389478927384" direction="recipient"> <state>early</state> </dialog>

With the 5.6 branch, when I press the button it calls '**' and I expect it to call '**221'


On older versions of Polycom, the behaviour was to send *97{ext} as is evidenced by the following pages regardless of the presence of the sip callid or the target id in the SIP NOTIFY


This page for 'Asterisk PBX' ( ) says to activate "notifycid=yes ". I am not using asterisk and I can't add the SIP CallID to the SIP Notify. 


I would like the phone to behave like the older polycoms behaved, where it dials '**' + the extension being monitored ( regardless of the target in the SIP Notify ).


How can I get this behaviour? I tried using 'legacy' option, but it didn't work.


All the posts on the forums that deal with 5.6.x + firmware says that I need the sip call id in the XML body of the SIP Notify ( which I can't do ) , so I am wondering how I can get legacy behaviour for the BLF?

Hello @dlublink,

welcome to the Polycom Community.

You mention "older Polycom Handsets" but fail to provide any details on this or the software version being used.


I am not aware of any bugs on this feature so please provide more details and maybe some logs / configuration on this.


The VVX310 for this example came from SCANSOURCE COMMUNICATIONS back in 26/09/2014.

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

Best Regards
