Posted: Thu Feb 25, 2016 6:15 pm Post subject: [Freeswitch-users] SRTP breaks my TLS session |
|
|
Hello list,I thought I had solved this issue by reducing my codec list to a minimum, but it still persists, unfortunately. This was to reduce the TLS packet size.
Anytime I enable SRTP on my phones, outgoing calls will randomly fail. The problem goes away when I disable SRTP. I only work over TLS.
Incoming calls work reliably with or without SRTP.
How do you suggest debugging this?
I tried setting up a fresh instance of FS but the issue persists.
Now. It should be noted that calls fail sensibly more often when I have more than one account registered on the same server with the same device.
Any suggestion is welcome. Have you experienced this?
I’m running FreeSWITCH Version 1.6.5 on Debian. My phone in this case is a Yealink SIP-T46G running firmware 28.80.0.95.

You may want to run a pcap trace on the Yealink. It’s under settings->Configuration. Start/test/export. |

Thanks for this.
This isn’t just a yealink thing. I’ve encountered sporadic issues with soft phones and other desk phones as well.
I didn’t use the PCap capture feature because I had assumed it would give me a bunch of TLS packets. I’ll test that and revert back.
How can we explain that I have more calls failing if I register multiple accounts?

Hello there,I can confirm that a PCAP gives me a bunch of TLS packets.
How do you suggest debugging this?
Thanks!

Hello all,Pinging the list in search of brilliant minds for more recommendations on how to solve this overwhelmingly frustrating issue.
I just love FS and all it lets me accomplish. But this bug and the unpredictability and inability to effectively troubleshoot just leaves a bad impression, accentuated by the fact that no one seems to care about it. I call it a bug because I do not experience this issue with other SIP servers.
Who is available to exchange SIP credentials in order to cross-test this? Especially if you believe you are immunized!
Best,
Emrah

This issue seems to be very connected to the network topology of the client. I am now having this problem with Bria on iOS.On FreeSWITCH there is hardly anything. First invite results in a 407 proxy required, and after that the session fails and FS reports a wrong_call_state.
Is there anyone here using tLS willing to provide me with a SIP account to test this over their instance of FreeSWITCH?
