[Linphone-developers] Send DTMF as SIP Info

[Gary Metalle]

Hi.

 

I’ve noticed (on the Windows version, not sure if others same) that if the ‘Send DTMFs as SIP info’ checkbox is checked in ‘Network settings’, Linphone sends DTMF tones twice; once as a regular audio tone and again in a SIP info message. Is this intended as it means the receiver gets two identical tones? I would have thought this was meant to be a one or the other setting.

 

Regards
