[asterisk-biz] PRI vs SIP vs ???

[Alex Balashov]

You know, Steve does have a salient point underneath however you chose  
to take the framing; there is not an intelligible notion of "better"  
to appeal to here, and any truly experienced and knowledgeable  
respondents will present it as a matter of taste with some pros and  
cons on both sides.

The distillation of some additional context or data points can, in  
many situations, make the case for one or the other more  
definitively.  For example, as others have mentioned, a wider variety  
of factors - some very stochastic - are brought to bear on whether SIP  
trunking will work well, whereas TDM is pretty cut-and-dried.  It  
either works or it doesn't.  On the other hand, it is quite a bit less  
flexible in a technical and economic sense, and requires greater and  
longer initial and OPEX commitments.

Steve is telling you that you are being vague because you 1) provide  
little data about the nuances of the requirements aside from saying  
that trunking of some description is needed and 2) based on this,  
asking which is "better?"

That's a little like asking, "O hai I want to go to space. Which is  
best way, space shuttle or Saturn rocket?  Other suggestions for  
spaceship????????"
