According to TCL developer guide, for leg senddigit, "Digit transmission fails if the leg senddigit verb is executed and the negotiated DTMF relay is either rtp-nte or cisco-rtp"
Here is what I referenced:
www.n-cg.net/ncgpdf/Cisco_TCL-IVRv2_Programming.pdf
This guide is from 2004. Does it still apply today? I couldn't find a more recent version.
Wondering if we can send digit over SIP trunk with TCL with rtp-nte.
