Highly recommend Sangoma for PRI or BRI, used both in the past, they’re straight forward to install and Sangoma officially support FreeSWITCH. We used the Sangoma A101E for PRI. FreeSWITCH installation guide and sample configuration here: https://wiki.freepbx.org/display/PC/Telephony+Cards+for+FreeSWITCH There are various models available depending on the number of ports and channels but you should always get the E version which includes the echo cancellation module (it’s tricky to buy the echo cancellation module separately): http://www.sangoma.com/products/digital-telephony-cards/ From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Deepika Yadav Sent: 04 May 2017 10:12 To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Subject: [Freeswitch-users] Freeswitch PRI support 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?
