[Asterisk-Users] RE: SIP TAPI

[Jerry Jones]

A big disadvantage for a hosted provider is creating manager accounts  
for end users. for a single company installation it may not be a big  
deal, but SIP TAPI looks much cleaner to me as a service provider.

Of course I have yet to get a good configuration for it working  
properly.
