Too Much Kool-Aid Can Make You Sick
• SIP is NOT simple anymore

•
•
•
•
25 RFCs - RFC 3261 longest ever by IETF
Still NO cheap devices, but getting there
Install base & video-conferencing STILL dominated by H.323
Firewall/NAT problems
CANNOT build a service on SIP alone

PSTN will be around for awhile
