I tried to open some dialogue with colleague members of the ITSPA about Vodafone’s legal challenge to Ofcom’s two-hour number port ruling.  Instead I got a number of offlist replies suggesting Vodafone’s challenge is still news to many in the industry.
Today, if you want to port your number from one service provider to another, it […]

I come from an IP engineering background, and now work in a telecoms role with Localphone.com. Huge amounts of crossover exist between the two disciplines, especially now that inter-company telecommunications interconnections are now regularly made over IP, but much of what someone will learn about peering in the voice world will not be mellifluous […]

“Ma Bell is a system I want to explore. It’s a beautiful system, you know, but Ma Bell screwed up. It’s terrible because Ma Bell is such a beautiful system, but she screwed up. I learned how she screwed up from a couple of blind kids who wanted me to build a device. A certain […]

I’ve been allowing the webcast of RIPE55 to mutter away in my ears all week and have let myself get distracted from time to time when the topics turned relevant to networks I operate or the chatter got interesting.  A bit like the end of today’s ipv6-wg session.

This describes a problem that I reported to the SER developers mailing list, and from the replies, I don’t think this will be fixed soon, hence this post for the search engines to find.
The SER plugin which supports MySQL does not build against current 5.0 versions, complaining ‘undefined symbol _pure_virtual’. Fixing that earns you […]

I replaced my — not very good — imported VOIP handset with a Snom 360. Conveniently, the Asterisk sip.conf has a loose default user for SNOM defined, but it’s not perfect, and certainly didn’t let me use the SNOM and voicemail properly.
