Re: [SR-Users] Recommended configuration for TCP support

In general, it happens in our network (as more and more Via headers are added). Sorry, I didn't understand your last sentence. What do you mean by not connect if there is no active connection after location lookup?

On the phones? If you use tcp and have phones behind the nat, it is recommended to not connect if there is no active connection after location lookup -- see core functions for tcp.

What is the recommended configuration when TCP is used? Currently, I only have the following: children=16 listen=udp:<ip>:5060 listen=tcp:<ip>:5060 disable_tcp=no tcp_connection_lifetime=605 (registration expiry is 600) Also, is there a difference with UDP regarding NAT handling?
