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.
- You can use sangoma pri card. We are using this from last 7years.
1. 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
- If you are using sangoma card. Then you need to install wanpipe driver
and configure wanpipe driver with freeswitch. Make sure to compile freeswitch with libpri. You can follow this https://wiki.freeswitch.org/wiki/FreeTDM#Installation
