Depends how you view the term broken. They don't comply with the 
standards, that's for sure. A lot of older Cisco kit is far more broken, 
as they have the G.729 bits packed in a different order from the rest of 
humanity.

Most recent versions of Cisco/Linksys software have corrected these 
issues. They allow you to use the wrong packing or the SDP tag "g729a" 
for backwards compatibility with their own kit, and standards compliant 
SDP and/or RTP for compatibility with other kit.
