Re: [Opalvoip-user] The callback function OnUserInputTone() has always the same value as duration.

[Robert J. <ro...@vo...>]

I have clarified the semantics of the OnUserInputTone() call back function, and made sure RFC2833 receiver, and the H.323/H.245 signal/signalUpdate handling, follows those semantics. In particular, getting a call back at "tone start" and one at "tone end". You should also get the actual duration of the tone as indicated in the RFC2833 packets.

Please note, as I said before, not everyone sends the correct information in RFC2833, so unless interoperability is not an important requirement for you, you may have problems doing anything that relies on the tone duration.
