libsip
libsip is a library implementation of the sip protocol as described in
rfc3261. libsip intends to implement
parsing the entire SIP Protocol, but will only provide helpers for certain
common use cases.
WIP This library is still very much under construction.

Running the examples
```bash
git clone https://github.com/Bytebuddha/libsip
cd /libsip
This example expects a server with the credentials in examples/udp_register.rs
to be running without it will fail.
cargo run --example udp_register
This example expects a server with the credentials in examples/console.rs
to be running without it will fail. It prints all requests received to the terminal
cargo run --example console
```

Alternatives
- parsip
Is only for parsing SIP messages. I wanted libsip to be able to handle some user case's
specifically Registration.
- sip-codec
I attempted to use this library first, lots of features are not implemented like writing
sip requests and a few other fairly common things. I also wanted SIP Headers to be in the form of an enum witch would have required
basically rewriting the whole crate.
