[Asterisk-Users] DID trunk suggestions for Asterisk

[Joe Cunningham]

I have a client that has 4 analog DID trunks which are wink start lines 
and are the incoming lines.  Each  trunk line has 20 DIDs assigned.  We 
are in the process of migrating them off their current system to 
Asterisk.   We need a way to get these DID trunks into Asterisk so we 
get the DID information to route the calls.  While the DID setup self  
is not the issue.  The issue is I am looking for an inexpensive way to 
get these trunks directly into the Asterisk box.  Since they are analog 
DID we need to supply the voltage to the CO.  I have looked at using 
something like a BrookTrout card but these are costly.   Also looked 
using something like the DID-200 to convert the DID trunk to loop-start 
again these have a high cost.  I also considered having the client order 
and switch to PRI and all the advantages this brings however I think 
this might be overkill for this client. Not sure of the month costs with 
this I was thinking depending on the term this may run about $500 per 
month.  I also thought about BRI but searching  Google and such first it 
looks like you can't do DID over BRI. 

So I guess my question is based on the above have I missed something and 
is there any inexpesive way to bring these DID trunks right into 
Asterisk keeping the current analog DID trunks?  If so what hardware is 
required?
