[Linphone-developers] Speex 3200 is null when trying to enable

[Lindsey Vastola]

I am trying to get my DTMF tones to work and I read that I need to enable speex 3200. When I run the following code, type is coming back as nil. What do I need to do to enable it?

let type = linphone_core_find_payload_type(theLinphone.lc, "speex", 3200, -1)

if type != nil {

linphone_core_enable_payload_type(theLinphone.lc, type, 1)

} else {

NSLog("type is nil")

}
