SIP.Grammar

The SIP Grammar provides rules and parsing mechanisms for SIP requests, responses, headers, and other structures. SIP.js makes use of the Grammar when parsing incoming messages. The Grammar is written using PEG.js v0.10.0 and compiled for size optimization.

If you are making source code changes to SIP.Grammar, be sure to run grunt grammar to rebuild the processed JavaScript file.
