One step closer to the Plug and Play IP PBX

SARK 500 flexibilityWouldn’t it be nice if you turned up to install an IP PBX and all you had to do was connect the lines and phones and everything just worked, with inbound calls automatically routed to the connected phones. With the combination of a SARK phone system plus snom and Yealink IP phones, it can be this simple.

Until now the reality has been quite different, the constant headache for telecoms engineers in setting up an on-site IP PBX has been in the configuring of extensions when they do not have control of the network. The largest time consuming element of any installation is the provisioning of the IP phones with the correct settings. Often getting this provisioning information to the phones has relied on special settings on a DHCP server . The problem with this is, that in most cases the telecoms installer does not have access to the DHCP server and even if they do, not all routers necessarily support this capability. The only option at this point is to manually set up each phone which is extremely time consuming and more importantly adds considerable cost to an installation.

The SARK development team led by Jeff Stokoe have harnessed a technology that has been embedded into snom and Yealink phones called SIP Multicast. During boot-up, the phones send out a SIP packet to a special IP address reserved for SIP Multicast. The SARK PBX listens to this address at all times and will respond, telling the phone where to get it’s configuration from. This achieves the same job as using the DHCP server but all the functionality is contained within the phone and phone system themselves. Therefore negating the requirement for the telecoms engineer to control the network. Furthermore, SARK will automatically generate extensions on the fly when it receives the Multicast message. The phone is then passed all it’s configuration information using an intelligent provisioning engine built into SARK. At this point the engineer has only had to physically connect and power up the SARK system and phones.

Paul Hayes, Product Development Director at ProVu Communications (the sole distributor for the SARK range of phone systems and distributor for Yealink UK) said: “The SARK system is designed to be accessed remotely, yet securely. In my mind this is essential for anyone wanting to install phone systems in any significant numbers. The zero-touch configuration system and remote access mechanisms in SARK allow engineers to manage systems without on-site visits, which significantly reduces both the installation and maintenance overhead for our resellers.”

ProVu Communications are the sole distributor for the SARK range of phone systems and the premier distributor for snom and Yealink phones.

ProVu turns up the volume on SIP phones

Algo Loud RingerProVu Communications has launched a new alerter product, the Algo 8180 SIP Audio Alerter that increases the ringing volume of SIP telephone systems for variable noise environments such as warehouses or factories. The device also auto answers for voice paging or full intercom systems.

Darren Garland, Managing Director of ProVu Communications, said: “The 8180 is typically eight times louder than a telephone speaker. This may seem ear piercing, but its SoundSure technology automatically adjusts the ring and paging volume to compensate for background ambient noise, therefore will only ring as loud as it needs to be heard.”

The product is equipped with a high efficiency integrated amplifier and tuned high quality loud speaker. The 8180 device is supplied to customers with several audio files pre-loaded to its internal memory for ringing sounds, but users are able to custom the system with personal audio files, music, sound effects or voice announcements.

Ian Godfrey, Sales Director of ProVu Communications, said: “The 8180 has been a hit with our resellers. It fills a gap in the market when our hosted or IP PBX resellers are looking to replace a more traditional telecoms solution where an existing loud ringer may have been in place. It takes them into opportunities that previously were not open to them.”

Reasons why NOT to buy the German variant of the Gigaset DX800A for use in the UK

Over recent days, having tested a German variant DX800A purchased from two of the Amazon UK German traders I have discovered the following:

  1. Fixed line is only configured for ISDN, major issue for most UK users unless they are connecting to ISDN.
  2. Outbound call “line” Selection differs: when you make a call using UK variant you can select from DX800/IP line (if set up), Fixed Line (PSTN) & Mobile. For German variant you can only select ISDN, IP & Mobile. I looked through the Web UI and can find no option to enable the PSTN.
  3. German language menu settings as default (we know about this already and can be changed in the menu).
  4. German language for answering machine voice option prompts which cannot be changed. This makes the answering machine completely unusable to anyone that doesn’t speak German.
  5. Gigaset.Net doesn’t and can’t be used for outbound calling (refer to point 2, need to call via the DX800A which isn’t offered as a connection path).
  6. German PSUs.
  7. German language UG.

The UK version of the Gigaset DX800A is only available to Gigaset Pro Authorised and Certified resellers.

Recently, we have successfully completed interop testing of the ProTalk SIP door unit with Broadsoft platform (not broadsoft certified).

Here is a quick how-to guide to configure ProTalk SIP door unit with Broadsoft Server.

Firstly, the firmware on the door unit has to be on VoIP version: 1.99.2. To check the firmware version, web browse to door unit and click on Service page.

Then set the device as follows:

  • SIP Proxy Server Address : (provided by server provider)
  • SIP Proxy Server Port : 5060
  • SIP Registrar Server Address : (provided by server provider)
  • SIP Registrar Server Port : 5060
  • Outbound proxy Address : IP address of outbound proxy server(provided by server provider)
  • Outbound proxy Port : 5060

Secondly, enter the user details. User name part is the only bit that is tricky. To get the username for door phone, look for “Line port” field under device configuration. Line port setting should be something like You only need to put name part of sip uri i.e. abc123_321 as username. Finally enter password and authentication password and press save changes to register the device. Click here to see a snapshot showing require Broadsoft server user details.
