[Linphone-users] Huge delay between 100 Trying and 180 Ringing

[s . maertens]

Hello,

I have several hardware devices, using linphone embedded, connecting to our Sip 
Server. They are connecting over internet.
On one of the connections I notice a huge delay between the "trying" "dialog 
establishment"packets and the "ringing" packet.

Any hints on how I can find out where the trouble might be? As the hardware 
devices have only a webinterface where I can change some settings, I cannot 
really go into debugging on the device itself.

I have attached a screenshot of the callflow I have traced on the sipserver 
itself.

Any clues are highly appreciated.

Best regards

Stefaan
