Might be helpful for someone to summarize exactly how GR303 is
similar or different to other signalling protocols (i.e. line
appearance, callerid, did, etc.).  Google doesn't seem to find any
really specific information about it (other than it existing).  For
example, is GR-303 similar to a PRI?  If so, how is it different from
a PRI?
