java - No RTP or SIP DTMF with libjitsi -

-

i'm trying add dtmf audiomediastreamimpl (from libjitsi). can in_band method, that's not optimal because compression problems can arrive.

but can't working version of rtp_dtmf or sip_info_dtmf, nothing happens.

i have tried use standard method :

public void senddtmf(final dtmftone dtmftone) {     // same code dtmfmethod.sip_info_dtmf second test.     mediastream.startsendingdtmf(dtmftone, dtmfmethod.rtp_dtmf, 100, 101, 100);      try {         thread.sleep(1000l);     } catch (interruptedexception e) {         e.printstacktrace();     }      mediastream.stopsendingdtmf(dtmfmethod.rtp_dtmf); }

i have tried stop rtp flux before, after, not use stopsendingdtmf nothing working.

i use libjitsi version 563.

if can't solution audiomediastreamimpl, create own sip_info_dtmf, have heard best method dtmf rtp version.

i have found how archive objectif.

the startsendingdtmf start new thread has task send dtmf. , throw exception because telephone_event not supported.

i need add more information in sdp transaction , add dynamic payload audiostreamimplementation.

the rfc 2198 / 4733 define how add media attribute.
