Re: [Sip] Binary Encoding for SIP

[Rohan Mahy <[e-mail]>]

Hi Raphael,

Just as an FYI:  The "unpopular" encoding for H.248 is ASN.1 encoding 
of the entire protocol.  What Cullen is proposing is sending all *MIME 
bodies* in SIP as a stream of raw binary data (like HTTP). This is 
instead of sending SIP MIME bodes as a stream of base64-encoded data 
for example, which is unnecessary in modern protocols, but was required 
in email for backwards compatibility reasons.

(btw: I vote for a)

thanks,
