[OpenSIPS-Users] use case for settlement free peering

[Bogdan-Andrei Iancu]

Hi AG,

To shortly answer you : yes, OpenSIPS is more then suitable for 
you...and OpenSIPS is very good SIP router.

You have module do dynamically control the DID based routing between the 
SBC (like dialplan module or DynamicRouting module), both of them with 
web provisioning interface (see the OpenSIPS Control Panel).
If you need any link, let me know.

Also you can use OpenSIPS for protocol conversion (TLS / TCP / UDP are 
all supported) both for IPv4 and IPv6.

Regards,
Bogdan
