[Asterisk-Users] RTP Ports mismatch & Astwind modem support
<html><div style='background-color:'><DIV class=RTE>Hello,</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>I have been rattling my brain and searching the mailing list for 1 week before posting.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>I am faced with the followng challenge.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>When using Xlite, all works well.</DIV> <DIV class=RTE>When using * there is no voice either way upon off-hook or even when redirected to voice mail(problem occurs with any VOIP provider).</DIV> <DIV class=RTE>Ethereal trace indicates, upon incoming call, a request from the VOIP provider with all codecs imaginable then a request from * to the registered x-ten lite (configured as the receiving extension with silence set to transmit) with only the G -723 codec. Then a request from * to Xlite for audio over RTP 8552 and then an ok from X-lite to * for audio over RTP 8000.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Configuration follows: ADSL direct connection to Win XP-SP2 box running Astwind, all correct ports are opened in the ICS/ICF firewalll and forwarded to the * IP. X lite registers correctly and internal calls to Voice mail are fine. sip.conf is very simple and follows X-lite sample config file. Nat is set to yes, canreinvite to no. rtp.conf states that rtp traffic starts at 8000 ends at 65000.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Any clue why I cannot receive/transmit voice at all via * while the Xlite works fine directly to the VOIP provider?</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Regarding Astwind, does anybody know if it supports a chipset modem 537 from intel as a card? </DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Thanks. </DIV> <DIV class=RTE> </DIV> <DIV class=RTE>An * evengelist !</DIV></div><br clear=all><hr> <a href="http://g.msn.com/8HMBENUS/2749??PS=47575" target="_top">Find the music you love on MSN Music.
