Asterisk RLS appearance on VVX 601 display



This is my first post and I am very much new to Polycom VVX phone.

I just accuire VVX 601 phone and evaluating for our production system, I would appreciate any suggestion or advice!


Many thanks to the post below, I was able to confirm Asterisk RLS feature with my VVX601 by following the instruction.


I am currently evaluating FreePBX environment, and to make the BLF listing to work, I set below in /etc/asterisk/pjsip_custom.conf with 20 of "list_item"s, 


type = resource_list
; Asterisk Resource List Subscriptions (RLS)
event = dialog
list_item = 10001
list_item = 10002
list_item = 10020
notification_batch_interval = 3000

and added  below in VVX's configuration file to make it work.


attendant.uri="asterisk-rls@<PBX's server address>"

This enabled the list of extensions in 4 x 4 matrix in LCD of VVX601, I could see 10001 through 10015 activities on LCD panel (1 is registered line), but I don't see the rest of extensions status.

Just wondering how to display the rest of them or simply it is a limitation of VVX601 that it can not show more than 16 "items".


Also, I prefer to show "Display Name" which is assigned to those extensions, and wondering how to do that.

Many thanks in advance,



- Asterisk: 13.23.1

- FreePBX:

- UC Software Version:

Hello @domosute,


welcome to the Polycom Community.

Your post ended up in our SpamFilter so I had to release it.


The VVX 60x range can only display a maximum of 16 lines as explained => here <= but you can possibly look at our Obihai range. We do not support these via this Community forum.


I am not to sure I can follow you on the name part but would need to see some form of logs.

Hi Steffen,
Thank you, 16 is more than enough number for our use, I am still investigating how to show name instead of extension number but user can live without name label.

It is very nice feature, thanks for the advice!
