is the original version of this clone:ASTERISK-26933 RTP instance does not use same IP as explicit transport (unspecified transport)
Environment:DebianAttachments:
Description:ASTERISK-26851 fixed an issue where you explicitly needed to set media_address on multihomed systems. Unfortunately, this code only works when transport is explicitly set on the endpoint and the transport is explicitly set to a specific IP.

This makes it impossible to configure an endpoint (customer) that can dynamically use UDP/TLS or IPv4/IPv6.

If transport is not set RTP should bind to the IP address used in the transport the endpoint is registered on

If the target of a SIP INVITE is an explicit IP address then we could determine the local IP address that will be used for the traffic and bind to that only.
