build(deps): bump xphone from 0.4.0 to 0.4.1

[dependabot]

Bumps xphone from 0.4.0 to 0.4.1.

Changelog

Sourced from xphone's changelog.

[0.4.1] - 2026-03-20

Changed

• Consolidated SIP URI-to-SocketAddr parsing into shared sip::resolve_host() — used by both outbound proxy URI parser and trunk server ACK routing. Adds DNS resolution and ;params stripping to both paths consistently.
• ClientConfig now implements Default — reduces boilerplate when adding new optional fields (tests use ..Default::default() instead of spelling out every None)

Added

• Outbound proxy support — route outbound INVITEs through a proxy separate from the registrar via Config::outbound_proxy (e.g. "sip:proxy.example.com:5060")
• Separate outbound credentials — Config::outbound_username / outbound_password for INVITE authentication distinct from REGISTER credentials
• P-Asserted-Identity — DialOptions::caller_id now sets the P-Asserted-Identity header on outbound INVITEs
• PhoneBuilder::outbound_proxy() and PhoneBuilder::outbound_credentials() builder methods

Fixed

• Custom headers not applied to outbound INVITEs — DialOptions::custom_headers and caller_id were stored but never sent in the SIP INVITE. Now plumbed through SipTransport::dial() → Client::send_invite() → wire format.
• Config.host containing host:port (e.g. "10.0.0.7:5060") no longer produces malformed SIP URIs with double ports. The embedded port is extracted automatically; explicit .port() calls take precedence.
• RTP port 0 in SDP when rtp_port_min/rtp_port_max are unset (default 0,0) — now falls back to OS-assigned ephemeral port instead of producing m=audio 0 which rejects media per RFC 3264
