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
