This situation can happen using the AMI Setvar action with the new dialplan function after the call is originated but before it is answered.</li><li>After the call is answered a reinvite is required.</li></ul><p style="white-space: pre-wrap; word-wrap: break-word;">A call to ast_sip_session_refresh() will handle most of the above cases. It does need to be executed under the channel's serializer. See pjsip_acf_media_offer_write() for an example call to ast_sip_push_task_synchronous().</p></li><li><p style="margin-bottom: 4px;"><a href="https://gerrit.asterisk.org/#/c/5909/10/channels/pjsip/dialplan_functions.c@1113">Patch Set #10, Line 1113:</a> <code style="font-family:monospace,monospace"> channel->session->dtmf = dtmf;</code></p><p style="white-space: pre-wrap; word-wrap: break-word;">If the dtmf mode does not change then we should exit early.</p></li><li><p style="margin-bottom: 4px;"><a href="https://gerrit.asterisk.org/#/c/5909/10/channels/pjsip/dialplan_functions.c@1116">Patch Set #10, Line 1116:</a> <code style="font-family:monospace,monospace"> if (pjsip_pvt->media && pjsip_pvt->media[SIP_MEDIA_AUDIO] && (pjsip_pvt->media[SIP_MEDIA_AUDIO])->rtp) {</code></p><p style="white-space: pre-wrap; word-wrap: break-word;">pjsip_pvt->media is not a pointer but an array name.
