Have not tested that scenario, so can't really help a lot. After the iceRestart the WebRTC client sends a SIP reINVITE? Is this reINVITE responded to by the other side (PSTN)?

@havfo yes after ice restart i send the sdp to the other side. the other side does respond to it with a 200OK, but then audio stops flowing. I do observe that rtpengine detects dtmf on the webrtc leg.
Maybe my PSTN gateway provider does not support reinvite

Is it possible to reinvite without relaying it to the other side? it seems like the reinvite does provide the fix for the jumping network on webrtc side but breaks the audio on the sip gateway side.

Actually rtpengine seems to detect dtmf from both side after the reinvite but it just doesnt comeout of either end.
