[Openbts-discuss] wireshark capture to check usrp clock, etc

[Walter B. <wb...@pr...>]

hi,

i've just captured with wireshark a file when using two cell phones. the
call was made and one of them suddenly hang up.

i cannot tell from this information what kind of problem it is (whether
it is clock, sim, etc) other than "destination unreachable", "port
unreachable". i checked the gsm and voip options but they seem to be
fine ... it says "ringing", "ok sdp (gsm)", "ack" and finally
"rtp(gsm)", then the message "destination unreachable, port unreachable
(protocol icmp)" in the main window. could somebody who uses wireshark
help?

thanks,
