Hi all, I am interested in interfacing a GSM modem to *. I've seen a few comments about doing this, but I'm not clear whether people have actually made it work. I've used GSM modems for various data jobs, mostly high volume SMS (no, not nasty marketing stuff - high volume solicited SMS :-) ) . These only have analogue ports for voice. Does anyone know of units with digital voice interfaces? Regards, Steve

Steve. Flosys makes fixed cellular interfaces. Although our main products come with FXS ports we designed the interface as interchangeable modules. One of our interface modules is a T1/E1 interface (based on an Infineon Falc56). So yes we do support digital interfaces. We also have a TDM interface card which allows to daisy chain several GSM(or TDMA or CDMA) units together to the T1/E1 master unit. P.S: Our FXS module uses the same chipset as the Digium TDM400P card. Regards. Alfred R.

Has anyone tried connecting * to a GSM mobile phone with internal voice modem? I'm trying to route calls to mobile phones out over a mobile phone connected to my * server via a serial connection. In this way these calls will be much less expensive than if they are routed via a landline. I'm guessing that I start in the modem.conf file but the only references on the web are a couple of years old and generally to people trying to use HCF modems as PSTN interfaces. Thanks Stuart.
Thanks for all of the contributions. I guess I'll have to junk the older phones and concentrate on getting the chan_bluetooth stuff to work. Looks like Friday afternoon will be: Install bluetooth drivers Install chan_bluetooth debug config repeat last step as necessary :-) Stuart Ronan Mullally wrote:>Hi Stuart, > >On Thu, 2 Dec 2004, Stuart L.
