I'm trying to setup a SONUS 1K in Brazil with Vivo as a provider
It's an E1 R2 CAS connection, but I can't get in or outgoing calls to work
This is my current R2 CAS profile
When I restart SONUS, I get this CAS-R2 CD Bit error
Does anyone have experience with SONUS and an E1 R2 CAS connection to Vivo?
