Sample project External IP parsing error

[naveline67]

using sample with external IP parameter throws parsing error

cargo run --example client -- --sip-server xxxx.xxx --user 00123456789--password xxxxxx --auto-answer --external-ip XX.XX.XX.XX

thread 'tokio-runtime-worker' (26828) panicked at examples\client\play_file.rs:26:52:
Invalid external IP: AddrParseError(Socket)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

But if I provide a port

cargo run --example client -- --sip-server xxxx.xxx --user 00123456789--password xxxxxx --auto-answer --external-ip XX.XX.XX.XX:0

then it fails immediatly

2026-01-22T11:13:39.3893228+01:00  INFO client: examples\client\main.rs:150: Starting SIP client
Error: AddrParseError(AddrParseError(Socket))
