Is anyone aware of a GSM femtocell that will trunk back to a VoIP softswitch
such as Asterisk?

I have not, but I have had great luck with OpenBTS.

Thanks,

Steve,
Thanks... my only problem is right now OpenBTS is not cost effective to
deploy to customers.

Most people seem to be concentrating on 3G femtocells (there are various
companies making designs based on picoChip soft radios).

OpenBTS can be used (and there have been some successful quite large
installations).

Hay Systems were meant to be producing a 2G (GSM/GPRS) femtocell, but
they seem to have gone quiet.

Steve,
Can you recommend any 3G femtocell to VoIP manufacturers? I'm coming up
very dry. OpenBTS sounds like it would work, but is way too expensive to
roll out to residential homes.

Pretty much all Femtocells use 3G locally and send stuff back over VoIP
(in some form or other).

In the UK Vodafone sell a 3G femtocell (which has an internal 2G radio
too, to ensure it's being used in the UK).

AT&T sell their own.

Try contacting PicoChip or Ubiquisys who both have femtocells.

I have done an OpenBTS research and try project and OpenBTS is working
great. A complete set to roll out OpenBTS is not cheap but as far as I
know all femtocell kind of solutions need serious investments and
OpenBTS seems to be the cheapest among them. Asterisk is actually one
of the lego pieces the OpenBTS solution is made of.
