<HTML><BODY>Hi.<br>1.<br> I'm trying to send 40 ms of speech in each RTP frame <span class="hps">when working</span> <span class="hps">with a specific/<span class="hps">certain</span> </span><span class="hps">gateway</span>.<br>By means of modifying [var.xml]:<br><p><X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMA@8000h@40i,PCMU@8000h@40i"/><br> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMA@8000h@40i,PCMU@8000h@40i"/><br>, it is possible to call FROM this gateway (gateway does not send ptime in SDP).<br>But, when the call comes from the other client with ptime set to 20 in SDP, outgoing INVITE messange TO this gateway contains ptime set to 20.<br>How can I set ptime to 40 (<span class="hps">it's desirable to do so only for one specific gateway</span>).<br><br>2.<br>I'm using FS for PTT (Push-To_Talk) services.<br>2.1<br>When FS gets incoming INVITE / reINVITE with "a=sendonly" in SDP and responde with "a=recvonly" it MUST *NOT* send RTP packets to UAC, but FS does so.<br>So, how can I fix this?<br>2.2<br>To start talking FS sends reINVITE (I use "uuid_media_reneg __uuid" command for this).<br>I need to add "a=sendonly" to this reINVITE.<br>How it can be done?<br><br></p><br>With best regards, Shumaev D.A., programmer @ KBR Ltd.<br><br></BODY></HTML>
