[asterisk-bugs] [JIRA] (ASTERISK-28817) chan_pjsip: constant DTMF tone if RTP is not setup yet

[Kevin Harwell (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-28817?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kevin Harwell updated ASTERISK-28817:
-------------------------------------

    Description: 
If chan_pjsip is configured for DTMF_RFC_4733, and the core triggers a digit begin before media or rtp has been setup then it's possible the outgoing channel will hear a constant DTMF tone upon answering.

This happens because when there is no media or rtp chan_pjsip notifies the core to initiate inband DTMF. However, upon digit end if media and rtp become available then chan_pjsip does not notify the core to stop inband DTMF. Thus the tone continues playing.
