NSE (Named Signaling Events) is a proprietary protocol to switch from voice to passthrough for fax/modem communication, without involving SIP. It uses a proprietary event, based on NTE (Named Telephone Events). NTE is not proprietary, but NSE is.
TelcoBridges and NSE
We currently support NSE events:
192 (switch to passthru) 193 (disable echo) 194 (switch back to voice)
This adds a new SIP SDP entry looking like this for initial negotiation:
a=rtpmap:100 X-NSE/8000 a=fmtp:100 192-194
The system does not send a SIP re-invite, but instead will send this NSE event 192.
