- A common thread for all successful VoIP and IP Telephony is the Voice expertise. The same can be said for the Video.

- Important question to ask your IP Phone vendor in a multiple site environment: When I dial Emergency Services in one site which PSTN Gateway does the call go out. Now I dial the same Emergency Services number at another site – which Gateway? How hard is it to make the Emergency Services call go out the local PSTN Gateway 1 st . New generation PBX programming is done using exception routing, some look more like programmes in perl or C. So a routing entry might look like this IF call from phone with IP Address 192.168.1.0/255.255.255.0 AND calling Emergency Services THEN send call to Gateway A first, Gateway B second IF call from phone with IP Address 10.10.1.0/255.255.255.0 AND calling Emergency Services THEN send call to Gateway B first then Gateway A IF call to Emergency Services (The default) THEN send call to Gateway B first then Gateway A

- SIP enabled IP Telephony and VoIP and VIDEOoIP with Presence and Instant Messaging. Control handed back to the user, no more forwarding calls from one device to another. Mums and Dads and researchers are using the services from 3 rd parties. Lots of hype and confusion in the market place. – watch out for destructive events (skype, and SPIT). All aspects of Telecommunications will be effected. SIP will bring mobility, freedom, cheap, and flexible. A new paradim in personal communication! Will have a larger Social and Economic impact than http? This community needs to work on SIP enablement of their infrastructure. Otherwise might University IT departments loose their users to a 3 rd party? How then will you proceed?
