Hello, i am working on a Linux platform with multiple interfaces (eth0 and eth1) using the pjsua interface. The transport is initially create with pjsua_transport_create and pjsua_transport_config.bound_addr is set to the IP address of eth1. All registration message correctly go over eth1. Once i change the IP address of eth1 and call pjsua_handle_ip_change() the pjsip library uses eth0 as registration interface and not eth1 any more. Is there a possibility to use the new API for  IP address changes and keep the previous interface? Thanks for any help, Martin
