[SR-Users] Recommended configuration for TCP support

[Mickael Marrache]

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?

Hello,

where are typically those issues with truncated SDP? 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.

Cheers,
Daniel

Hi,

 

We sometimes get issues caused by truncated SDP bodies. Therefore, we are
looking at using TCP instead of UDP.

 

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?

 

Thanks,

Mickael
