[OpenSIPS-Users] Fwd: Opensips + RtpProxy: media stream timed out while starting

[Semen Golubcov]

You mean 5061? The packets are encrypted, i will try to capture them with
ngrep and decrypt with the private key using wireshark and post the
decrypted data to
gist.

The message about late back means it is probably not routing.

Install ngrep and run

ngrep -qtd any -W byline port 5060

On OpenSIPS during the call.  Paste the output to a gist on gist.github.com
and include the link in your next reply.
