[Asterisk-Users] R2-Digital (Q.421)

[Steve Underwood]

Hi Jesus,

FX is not a variant of R2. It is a completely different signalling 
protocol. This means your service provider is using R2 for some of your 
channels, and providing all your incoming calls on those channels. It is 
use FX signalling for other channels, and you must make your outgoing 
calls there. Someone else told be about a similar configuration. I think 
they were able to use chan_zap for the other channels, and make use of 
its FX signalling features. I am not sure how that works, as FX 
signalling over E1s is far from standardised.

Regards,
Steve
