The best option would be to locate another VoIP provider with better service. For the PRI card, you will either need a PRI provider But eitherway ... if you want to use PSTN cards with FS, you should check the manuals as depending on the branch you buy, you should use a module or another. 2017-05-04 10:12 GMT+01:00 Deepika Yadav <deepikay@iiitd.ac.in>:
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?
Regards, Deepika
