[Freeswitch-users] Freeswitch PRI support

Thu May 25 09:09:37 UTC 2017

I once built a system for a cellphone rental company in Israel, at the time
termination to Israel was very expensive, they wanted to provide a local
USA DID to ring on the Israeli mobile phone, so they bought a 32 channel 2N
3g gateway, they had a deal with the mobile carrier that they got a couple
of thousand minutes per SIM to call any other SIM in the account (they
called it VPN minutes) then the customers would call the USA DID which
terminated the call through the 3G gateway, they set limits on each SIM how
many outgoing minutes it can call, the 3G gateway distributed the calls in
round robin until a sim used its allowed minutes.

So they were able to offer a USA DID to ring to the mobile phone at a very
low rate, but the market has changed significantly and its a lot cheaper to
terminate the calls via sip trunks, and by doing so the called party also
got caller ID.
