We already contacted the company and they may or may not fix their phones (my Chinese is not what it used to be J) however, regardless, this phone’s customer-base in Australia is huge as well as worldwide and a mass firmware update is not a viable option.

For us, this is one of those instances where a custom SIP “flavor” implementation to support these devices is immanent.

These phones are working on in-band DTMF for years because of their “special” RFC2833 implementation.

We’ll test the patch and let you know.

Thanks for the support!

Can you contact company who makes this phone and ask them to explain what reasoning they would have to deny a call based on an innocuous sip header that should not influence the codec negotiation in any way?
Especially one recommended by the RFC.

This may be a Denial Of Service on the phone and I'm sure they would want to be notified that their commercial product that they sell and make money on is not behaving properly.

Both calls initiated via an event socket command: api originate sofia/default/1001 &park

Let me know if there's more info needed.

Can you capture the FS console in debug level with TPORT_LOG=1 and max sofia debug env set please?

start up FS in the foreground with these env vars.

#TPORT_LOG=1 NUA_DEBUG=9 NTA_DEBUG=9 SU_DEBUG=9 /usr/local/freeswitch/bin/freeswitch

enter: console loglevel debug (or press f8)

reproduce the problem

thx

Hi Brian,

I might have a blonde moment but I don't understand how you want the raw sip
packets... Isn't that just binary data?

I've cleaned my post in pastebin and removed all the Ethernet and tcp/ip
data off to make it a bit more readable: http://pastebin.freeswitch.org/4545

I also attach the two capture files here.

Hopefully, one of these is what you mean by raw...

Sorry

Please put up the raw sip packets for us to see. This broken down
stuff in wireshark is so hard to read.
