Answer supervision - R2

[s.uziel]

Hi everyone;

I have a AS5300 Connecting to a E1 - R2. and I receiving calls from a partner (using an AS5300 connect to a ISDN switch), but he is asking for an Answer supervision, because he seems to have an ASR of 100%.

Is it possible to have Answer Supervision with R2 Protocol ?

E1 R2 protocol provides answer supervision. Have a look at the following URL for details of how R2 works:

The AS5300 would be getting an answer indication on the E1 R2 trunk from the external device, then passing this answer signal to the originating side.

What is the AS5300 connected to, and does it provide the indication that the call was picked up?
