Hi all,

We have been using Freeswitch+Sangoma for PRI deployments(ISDN).

But now when we are planning to deploy Freeswitch+Sangoma in SS7 environment, we discovered that there is hefty NSG license cost involved from Sangoma (apart from E1 HW cost).

Can anyone please help.. Is there any other possible way to deploy Freeswitch+Sangoma in SS7 environment.

Also, looks like Astrisk has libss7 library to make Sangoma Cards work in SS7 without NSG license.

Please advice.

Thanks a lot,

Vishal.
