That documentation is horribly outdated.

Where do I find more recent documentation?

Isnt there a way to make the kernel module work in the same way siproxd
works and able to support multiple phones? Right now configuring SIP
connectivity is a messy thing that is not easily setup. Can we fix this?

It should work fine with multiple phones, it even recognizes calls
between two internal phones and makes the media stream go between
them directly. Depending on how your registrar/proxy works, you might
have to set one or both of these module options:

Loaded both sip modules without specifying any parameters. Resulted in one
way audio problems which is what I also get without the modules.

sip_direct_signalling: when set to zero, allows incoming signalling
 connections from other hosts than the registrar. Usually not needed.

sip_direct_media: when set to zero, allows incoming media streams
 from other hosts than the registrar. This one is often required,
 some providers use server farms for handling the media streams,
 some set up media streams to go directly between the endpoints.

Ok will try setting that parameter to zero.

You of course also need to accept the packets marked RELATED by
the helper. If this is missing it might result in one-way audio.
