Please check that you use UDP transport.
Linphone has issue in in NAT traversal when used TCP or TLS transport.

Hi,

when calling to a linphone on a VPN without SRTP enabled on the leg-B,
FS does

[INFO] switch_rtp.c:6411 Auto Changing audio port from
192.168.1.35:7076 to 172.16.23.207:7076

But it doesn't when SRTP is enabled on the leg-B.

How to force that behaviour when SRTP is enabled?

Kind regards,
JCh
