ANI is not available with E1R2 dtmf signaling. For all other E1R2 options, ANI is available and you need to select this option to have ANI send out.

    Is there a way to support caller name (besides caller ID) with E1 R2? I haven’t find a way to do so. Maybe it is not supported by E1 R2?

    No, R2 does not suppport caller-name at all. It is an ancient signaling system 🙂
