I’m at Convergence Summit North. I have to say I think I prefer it to Convergence Summit South for what it’s worth. It’s in Manchester and I’ve also decided I like Manchester, again for what it’s worth. Travel and tourism piece over:) I tend to think long and hard about whether to visit a trade […]

How to make your VoIP secure #fraud

It’s a pretty simple process to set up your own VoIP phone system. Google “free VoIP server” and you will find links to 3CX or Asterisk. Download their free software and install it on a computer in your office. Sign up for a few SIP trunks from an Internet Telephony Service Provider (eg Timico) and […]

What’s in a bowl of fruit – IPCortex RaspberryPi

It never ceases to amaze me what we can do with technology. The most generous Rob Pickering of IPCortex sent me a RaspberryPi microcomputer loaded with a cut down version of his PBX. It was the work of minutes to set up a couple of Lincoln area code (01522) SIP trunks and then define some […]

I have seen the light, opened the door and been let in by ProTalk

I love it when our engineers come up to me and say “want to see something interesting?”. Today one of our top VoIP engineers showed me the ProTalk IP (SIP) antivandal door entry unit.  This is a rock solid door entry system controlled by SIP video phone. Pressing the button initiates a sip call to […]

#VoIP SNOM #SIP and the Football #WorldCup

When I first started looking at SNOM phones, perhaps 9 years ago, they were not very impressive. The handset was easy to knock off its cradle and the voice was tinny. The phone firmware was impressive and the fact that SNOM was a very early runner in the SIP market is to their great credit.  SNOM […]

What are ISPs doing about Voice?

The question is being asked “what are ISPs doing about voice?” This is particularly relevant as the market consolidates and B2B ISPs not only seek economies of scale but additional sources of revenues. Timico was founded as a fully converged ISP from the outset. Early on we had to decide whether to simply white label […]

10 years ago this month saw the publication of RFC2543 which was the first proposed version of the SIP standard that is now used an almost all internet telephony services. This is being celebrated this week at IETF74.  The Internet Engineerng Task Force is the body that maintains standards  for internet related technologies. SIP was initially championed by […]

Standardisation Brings Choice

Most of the Timico staff who have been subjected to my technology staff intro presentation, which is practially all 130 of them over the last 4 years, will have had my spiel regarding the competitive benefits of standardisation (eg IBM PC, GSM phones, SIP). Basically standards increase choice and reduce costs. Our position regarding the support […]

September 11th

It is 7 years to the day when the 9/11 tragedies happened in the USA. The event has different memories for us all.  I was attending a SIP Summit VoIP conference in Austin Texas and Tuesday 11th September was the first day. The conference was abandoned after the first day and most Americans hired cars […]

Nortel carrier strategy

Had a really good meeting with the Nortel Carrier team on Wednesday – I’ve not really had a chance to write it up and post before now. The meeting was held to discuss their SIP/multimedia product roadmap. The Nortel Enterprise Division has been making a lot of noise in the multimedia/Unified Comms space (SCS500 – […]

How will 21CN affect my telephone line?

We had an enquiry from a customer this morning: “I am persistently being contacted by David from ***** who has advised me that with 21CN BT are changing every business line from Analogue or ISDN to a SIP network and that there is no choice in the matter”. David was trying to get the customer […]
