Arnd, You may use SER MediaProxy if you wish real-time statistics and accounting of network traffic. See some captured example: http://www.ag-projects.com/MediaSessions.html http://www.ag-projects.com/CDRTool.html Adrian On May 2, 2004, at 12:00 PM, serusers-request(a)lists.iptel.org wrote: > Send Serusers mailing list submissions to > serusers(a)lists.iptel.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.iptel.org/mailman/listinfo/serusers > or, via email, send a message with subject or body 'help' to > serusers-request(a)lists.iptel.org > > You can reach the person managing the list at > serusers-owner(a)lists.iptel.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Serusers digest..." > > > Today's Topics: > > 1.

[Serusers] Any way to list rtpproy bindings?
by Arnd Vehling 01 May '04

01 May '04

Hi, is there any way to list the current rtp-proxy bindings? Searching through the source code ive found that rtpproxy understands a "L" or "l" command to list the current bindings. I tried to "echo "L" > /var/run/rtpproxy.sock" which results in an error and i tried to communicate with ser via a perl-script (see below) to no avail. Could it be that rtpproxy can only communicate with one process a time? Is there any other way to dump the list of udp bindings? best regards, Arnd ----------------------- #!/usr/bin/perl use IO::Socket; $client = IO::Socket::UNIX->new(PeerAddr => "/var/run/rtpproxy.sock", Type => SOCK_DGRAM, Timeout => 10 ) or die $@; print $client "L\n"; $answer = <$client>; print "proxy said: $answer\n"; close( $client );

[Serusers] multiple sip phones behind one NAT gateway
by Ronald Ramos 01 May '04

01 May '04

Hi, I have a problem on calling between phones behind one NAT gateway, the call make it but the problem is we can't hear ourselves talking. When I'm making a call outside the NAT I'm in, call makes it and we can really talk, I use STUN server for this. Is there a way I can identify different phones behind one NAT gateway? For example by using different ports on the SIP phone? Ronald
