The only real advantage over a regular SIP trunk from any provider, it's that you could select a plan than MAYBE allow you some sort of flat-rate and not per-minute use plans ... but it doesn't worth the effort and money you have to spend to get that to generate revenue ... also most of celullar carriers withh put some restrictions on the usage of the flat-rate, as all of them have 'fair use' policies. At least on Spain, it's ilegal to resell that kind of traffic and I asume its the same in most of the world. 2017-05-10 15:04 GMT+01:00 Colton Conor <colton.conor@gmail.com>:
So how does this GSM stuff work in the USA? Would I got buy a cell phone plan from someone like AT&T or T-Mobile, and then insert the SIM into these devices. The device would then covert the audio from GSM to SIP, and then I could use it like a SIP trunk?
What is the advantage of doing this over just buying a pure SIP trunk from an internet provider?

There's another chinese brand that has a 32 port, I've used it, works pretty well, i think it's "GoIP" or something.

Hi,
I searched some gateways online. The ones available at ebay are cheap, the following link shows a gateway supporting 32 SIMS for $859 :
http://www.ebay.com/itm/GoIP-32-32-Port-VoIP-GSM-Gateway-wit h-32-External-Antenna-/291811535942
However, when I contacted a company called "Matrix Telecom Solution", they gave the quote of $4150 for similar number of SIM support. On asking them to compare the two gateways, they said that the one available at ebay is a Chinese gateway about which they are apprehensive for the quality, warranty and working.

For PRI you use Sangoma or Patton.
But, why don't you use an hardware gateway sip<->gsm?
It would save you very big money.
Check on ebay and google, there are many of them, you put SIMs inside, and you are good to go.

Hi,
I am using Freeswitch in an application that initiates conference calls amongst 20 users in cellular network (mobile phones in GSM network). Currently, for the VOIP-GSM gateway, we are using the service from a company called Doorvaani.
But, since, the cost of call estimates to be high and we cannot debug the call drops; we are thinking to buy our own PRI card.
I am seeking recommendation on following points:
1. Which card should I buy that is most easily configurable with the Freeswitch i.e. company and type. 2. Reference on how should I start to make Freeswitch configure with the PRI card and start sending and receiving calls. For the current gateway service in use, I simply put the authentication credentials for the corresponding VOIP line offered by the company Doorvaani in the external SIP Profile. In case of PRI, what all changes are needed?
