SIPXECS 404

On SipXecs when you get a 404 not found, it does not only mean the user was not found, it means that the registrations string was not matched, so it is quite possible that the server aliases are not put under the Domain so strings do not match


XXXX@sip1.sip.company.com needs to match
add sip1.sip.company.com under Domain =>Alias

listen to g722 RTP streams in a PCAP file

The easiest way to listen to g722 RTP streams in a pcap file is to

1. Open the pcap file and just save the RTP packets (remove the RTCP using the filter rtp.ssrc!=0xBADBADBA)

2. Upload the file in http://pcap2wav.xplico.org/ and download the wav files

Many Thanks to http://pcap2wav.xplico.org/
