It is Easy to become a Bellhead

Many in the VoIP industry use the term Bellhead derogatively. Usually it is reserved for the loathsome phone companies and equated with people using circuit-switch technology as well. But I am of the opinion that it has nothing to do with the technology. There have been many recent examples of companies in the IP domain have revealed their bellheadedness. Some choice quote from a recent story about cable companies’ plans for VoIP applications. (Hat tip: Andy Abrmson).

“SIP has some shortcomings in primary line voice. Putting a lot in the end device is tough to scale, because every time you add more subscribers, you have to add equipment, and there are security issues.” (And you thought the intelligence has moved to the end?)

“CableLabs has collaborated with 3GPP to cross-pollinate specifications, producing cable extensions to the IMS spec and IMS extensions to PacketCable 2.0 including a feature server and service engine components supported by a consolidated customer database serving all applications.” (So forget about going where applications are; you need to get them only via Cablecos.)

“IMS and SIP support 7-Kilo-hertz “high definition voice” codecs, nearly double the speed (sic) of standard telephony codecs and able to produce quality that “sounds like natural voice,” he said.” (So will they stop shipping ATAs and instead supply new phones?) Of course not: “Black phones don’t get replaced often”.
