Caller does not rings #62

Closed AverkinSergei closed 8 years ago

I have a working application based on library pjsip4net. But, unfortunately, when you call from a telephone on my application the caller does not rings. What can you recommend?

Hi, please define 'does not ring'. pjsip4net comes with a couple of default sound files in the following folder https://github.com/siniypin/pjsip4net/tree/master/pjsip4net/Sounds. However, it doesn't play any of them by default, giving a developer a chance to provide their own files and connect to events of interest. An incoming call is accompanied by a Ring event https://github.com/siniypin/pjsip4net/blob/master/pjsip4net/Interfaces/ICallManager.cs#L18 telling app developer whether it has to playback a ring tone or mute it.

Subscribing to event: https://gist.github.com/siniypin/9c30a6d33c1734e77954 Playing a sound: https://gist.github.com/siniypin/08aba26ffea06915136d

Caller is ip-telephone. I can not handle any events on ip-telephone. When you are calling from ip-telephone on my application and waiting for an answer, you do not hear any beeps in the handset. How can I generate some sounds on remote ip-telephone?

siniypin commented 8 years ago

Let me double check - do you want to generate sound on a caller? Is caller a pjsip4net based app?

Oh I got it. Pjsip doesn't reply with provisional responses, as long as not sending them is the default setting http://www.pjsip.org/docs/latest-1/pjsip/docs/html/structpjsua__config.htm#a41d0fcd0a69f2996a6803a17e4cdf8b6 To enable the ringback tone on your devices set a corresponding config property Require100Rel to true.
