Securing Configuration Files with HTTP Authentication

  • Hackers are routinely scanning IP addresses for open ports and if they find an IP address vulnerable to brute force scanning they will execute a remote Provisioning scan using the first 6 digits of popular vendor ID’s like Polycom, Yealink and then brute force the last 6 digits of a 12 digit MAC address.
  • By example a ScopTEL server using the default HTTP listen port of 5555 can be attacked using this method. Other vendors are also vulnerable on whatever HTTP listen port they use to remotely provision IP phones.
  • TFTP is especially vulnerable on UDP port 69 because no specific path is required to the MAC.cfg file. Only the <MAC>.cfg variable is required to harvest the MAC.cfg file. TFTP should be denied on the Firewall whenever possible.
  • If you have enabled Telephony>Configuration>Security>Flood Protection and the ScopTEL Firewall and Telephony Flood Protection (Fail2ban) Service then the remote attacker’s IP address will be blacklisted by the Firewall when a brute force attack is detected.
  • But if the remote attacker knows of a valid MAC address on the network then this MAC.cfg file can easily be harvested unless HTTP Authentication is configured. The exact methodology won’t be published here as this should not be public knowledge.
  • This document will explain how to lock down a server using HTTP Authentication

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).
