<body class='hmmessage'>i think what you have is a Codec problem.. i have faced similar problem with a remote phone when internet was not able to carry G711 "which is used by defaul" so chage your codecs to G723 or GSM and it will work fine.. <BR><BR>

<P class=EC_MsoNormal>Hi everyone!</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal>I have been reading for a couple of days online in order to setup a remote phone, but no luck so far. The remote phone registers and I can call extensions, but the call only lasts 19-21 seconds before it drops (when I call from remote phone). When someone calls the remote phone we cannot hear each other.</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal>The scenario is de following:</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal><B>Office</B><BR>-Router configuration:</P>
<P class=EC_MsoNormal>-Ports being forwarded to Asterisk</P>
<P class=EC_MsoNormal>-UDP = 5060<BR>-UDP = 5004<BR>-UDP = 5060-5065 (configured range on rpc.conf first)</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal><B>House</B></P>
<P class=EC_MsoNormal>-Westell Modem configured as IP-Passthrough. In other words, the phone has a static public IP address.</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal><B>Phone:</B></P>
<P class=EC_MsoNormal>-STUN Server configured. I also had to configured symmetrical RTP because on the other side they couldn’t hear me. The call only lasts 18-21 seconds until it drops.</P>
<P class=EC_MsoNormal><B> </B></P>
<P class=EC_MsoNormal><B>Asterisk Configuration Files:</B></P>
<P class=EC_MsoNormal>-I configured external and lan IP.<BR>-Enabled NAT for the remote extension.</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal>What am I missing? Why is it that I can call from remote phone and hear the person, but they cannot hear me. When the office calls the house we cannot hear each other.</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal>Today I configured Asterisk with a public IP address and the home phone work just fine. However, I do think think this is the best setup because having Asterisk expose to the internet is not a good idea. I want to be able to have remote phones with Asterisk behind a router (private IP address).</P>
<P class=EC_MsoNormal> </P>
<P class=EC_MsoNormal>Thanks in advance.</P>
