RTP can't be "Decode as" RTP in G711 PCMA [closed]
Hi,
I have a issue with some VoIP tracefiles,not all, i can't "Decode as" my RTP stream.
i see, after my UDP, ? KNX/IP Unknown Service Family ? KNX/IP Header: Service = 0x11ce ? Unknown data (44 bytes)
ok, i try to apply "Decode as" RTP, but it doen't work. i try again, KO but i see;
Field Value Type Default Current
UDP port 40026 Integer,base 10 (none) RTP (my first try)
UDP port 40026 Integer,base 10 (none) (none) (when i try again, the port 40026 is already seen in RTP, but doesn't decode, and this, for each port)
it seems to me that if the SIP exchange is not seen,in my case it's TLSv1.2, the RTP is not decoded naturally? But with some pcapng I didn't have these decoding worries.
My version is 3.2.6 (v3.2.6-0-g4f9257fb8ccc)
Thanks
Best Regards
Michel

Setup Decode As... with these values
Field Value Type Default Current UDP port 40000 Integer, base 10 KNX/IP RTP
For my part, I disabled this protocol to have only UDP. Then I applied "decode as" RTP, it worked.
