[OpenSIPS-Users] Selective International Call Blocking

[Mike O'Connor]

Hi All

I'm working with a company running an old version of OpenSIPS (1.6.4), 
who need to selectively block international calls. What was the 
recommended method doing this back then?

I've been contracted to upgrade the whole system to current version of 
everything but that is going to take time.

Thanks

Mike
