Hi, Googeling about this shows that FS aims to support this (in fact it supports all 3: UDP/TCP/TLS). Yet I could not find the way to configure FS in order to support that. In fact, it does not work in my current install. I have TLS configured and work, but could not make TCP works thanks in advance /tzury

It just works... to force TCP you append ;transport=tcp

In reality you should be using SRV records.

Hi Brian

In fact this is exactly what I did and I could not get it work.
I am using a console based application supplied by pjsip.org and when
trying to register i get some error messages saying 'invalid transport
"SIP/2.0/tcp"' and 'REGISTER (30669) has invalid Via'

using the very same client against iptel.org seems to work.

Quote:

can you please elaborate a bit more about this?

I am dumping below the cli output.
thanks in advance for your time and attention

I need to see the sip packet. TCP should be uppercase I'm pretty sure.

you mean the via should be Via: SIP/2.0/TCP right?

If so, then that would a bug in the client then.

Some things might accept it but sofia is usually strict about some of

Hi Brian,

Just for your information here is a mail I got from a colleague of
mine which I consider as an experienced freeswitch integrator

Quote:

"... TCP used to work, and I had about 20-30 client phones connecting with it.
About 3 months ago I did an upgrade and TCP no longer worked. I was in panic mode, so I just ended up walking my
clients through reconfiguring their phones to use UDP.

It is definitely a bug in Freeswitch. I can help you work up a jira bug report if you like.
The bug happened somewhere between svn version 9800ish and 13223.
13223 is the version I'm running on my systems now, older, but stable for me..."

It would be just great if you can confirm the TCP functionality in the
latest release of FreeSwitch

Brian/Bakko,

Would you please tell me which softphone are you using?
As you know, my own one is not working and when I tried tcp with xlite
(providing transport=tls) I see in wireshark that it is still
transporting it over udp(!)

thanks allot in advance,
Tzury

Snom 320 phones are known to work as well if you set up SRV records for the
TLS.

I haven't tried other softphones because, basically, FreeSWITCH is a better
phone than anything else I can find.

To debug this, try wireshark or tshark to find out whether your softphone is
trying to connect over the TLS port at all.

Well, as I said at the beginning of this thread, TLS works fine for me.
The problem is when using TCP (transport=tcp and not transport=tls)

I'm not sure whether that's supposed to use TLS. I suspect not.

Jason,

I think I confused you with this TLS/TCP thing.
For the sake of clarification, I am talking about TCP and _not_ about TLS.
That is simply transporting the signaling packets over TCP instead of UDP.
No TLS should be involved at this stage. It is simply communication layer matter.

I can confirm that transport=tcp works fine here from one FreeSWITCH to
another. (I'm doing it over IPv6, but that shouldn't make any difference).
