Hi,
I searched some gateways online. The ones available at ebay are cheap, the following link shows a gateway supporting 32 SIMS for $859 :
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:
- Which card should I buy that is most easily configurable with the Freeswitch i.e. company and type.
- 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?
