How to Share One Extension With Multiple SIP Devices

Description: Shared Users for Devices

  • In many cases it is desirable to have an extension shared across multiple devices. For example you have an extension 100 and you want it registered to multiple SIP User Agents such as: SIP Soft Phone, Wireless SIP Phone (DECT, WiFi), SIP Desk Phone. When someone calls extension 100 you want all devices to ring or ring with unique ring tones or just blink because you are monitoring extension 100 for someone else.

Normally a SIP extension can only be bound to a single IP address so you cannot share an extension with multiple SIP phones or there will be IP address conflicts.  ScopServ has introduced a new feature to solve this problem.  Follow this official documentation if you want to enable Shared Devices for Extensions

Product Bulletin: Change on Yealink Phone Provisioning Volume settings when using Firmware 80+

We just release an update on ScopTEL Telephony package (scopserv-telephony-  that reflect changes made on Yealink firmware 80 for Volume settings.

Those patches are fully tested and resolve issues on T48G fw revision

The problem is related to this release note in version 80

Yealink Firmware 80 Release Note (See page 2)

Optimized the permitted values and default values of the sending volume in the new version of 80.

Previous releases had the following settings to default values which ScopTEL used in the APS

voice.handfree.spk_vol = 8
voice.handset.spk_vol = 8
voice.headset.spk_vol = 8
voice.group_spk_vol = 8
voice.handfree.tone_vol = 8
voice.handset.tone_vol = 8
voice.headset.tone_vol = 8
voice.handfree_send = 25
voice.handset_send = 35
voice.headset_send = 29

But Yealink has optimized v80 firmware default volume settings using a default setting = 0

The ScopTEL Phone Provisioning commits now set the supported volume options as per Yealink default recommended values:

voice.handfree_send = 0
voice.handset_send = 0
voice.headset_send = 0

Also, we now disable the Confort Noise Generator (CNG) setting on Yealink Provisioning.


If you have configured Automatic Provisioning System (APS): Phone Provisioning>Provisioning>Firmware Version: drop list = Version 80 (or later)  and you have updated your ScopTEL installation to package version scopserv-telephony25.noarch 20151016: you must update your Yealink phone firmware to minimum release X.80.0.70 (where X is the hardware platform of your Yealink phone).

You can download this firmware release from Yealink’s support site at:

Product Bulletin 6/25/2014: Yealink Phones do not download provisioning files after updating to scopserv-telephony25-

During the finalization of APS support for Yealink Version 72 firmware, ScopServ included a configuration line in Yealink <MAC>.cfg files which broke the phone’s ability to download edited <MAC>.cfg files after the initial configuration download.  While the first configuration file download would be successful and the phone would provision, subsequent attempts to download edited <MAC>.cfg files would fail.  The resulting symptom is a Yealink phone that would not update registration passwords, changes to DSS Keys, etc…

The problem affects any Yealink phone configuration file generated by the ScopTEL APS from version scopserv-telphony25- but patched in scopserv-telephony25-

In order to recover from this scenario the following actions must be taken:

1. Update the ScopServ Telephony rpm to version scopserv-telephony25- using either the ScopTEL GUI Package Manager or scopserv_yum update commands.

2. Force Commit of APS changes in the ScopTEL GUI

3. Factory reset each affected Yealink Phone by holding down it’s OK button until prompted for a factory reset, and confirm the reset.

4. Once the reset is complete and the Yealink phone has downloaded the new <MAC>.cfg file, the phone will operate correctly and be able to download edited <MAC>.cfg files from the ScopTEL provisioning server.

ScopTEL Incoming Lines and Ringing Service Modes

Automatic schedules are great when you want to set up Incoming Lines to predetermined destinations during closed hours, weekends, and Holidays.

But what if you want to override your schedules and set up predetermined destinations for unforeseen emergencies or early closures, or just can’t be bothered to set up automatic scheduling?  ScopServ refers to this feature as Ringing Services.  Also known as Night Service…

Not only does this document explain how to set up Incoming Lines on your ScopTEL PBX but it clearly explains how to set up manual schedules that can be toggled on and off with a feature code or programmed to a DSS Key WITH BLF STATUS so you know when the Service Mode is ACTIVE.

Product Bulletin: Changes to DND Activate and Deactivate Features Code

In ScopTEL Telephony revisions prior to 2.7.7 the DND Activate Features Code would allow a device or user to dial the code and activate DND in the telephony database.

Dialing the code when the extension was already in DND enabled status would allow the same code to deactivate DND enabled status.

The same scenario was also true for the DND Deactivate code.  The deactivation code could both enable and disable DND status.

While this was convenient for some users this was not ideal for Yealink T2X series phones with firmware revisions prior to x.71.0.137.  These phones would execute the DND codes on a reboot to refresh the DND status after the device re-registered.  In these cases an extension already in DND disabled status would toggle into DND enabled status after the device finished its reboot.

Since Telephony version 2.7.7 ScopServ has split the DND functions so that the DND Activate code can only ever activate DND enabled status and the DND Deactivate code can only ever deactivate DND enabled status.

If you have devices with hard coded DND buttons mapped to DND Activate *78 and for example you have a Features Code defined for DND Deactivate *79 you will notice that you cannot press the DND button again to disable DND enabled status.  To restore the previous behavior you must change the DND Deactivate code to match your DND Activate code.  As in this example you must edit your Features Code configuration and set DND Activate *78, DND Deactivate *78 then save and Commit your configuration changes.  WARNING: If you decide to implement this behavior ensure any Yealink phones you have on your network are upgraded to a minimum revision of x.71.0.137
