[Asterisk-Users] Quick Caller ID and Voicemail ?s

[John Todd]

[apologies for top-posting]

I am very interested in what providers typically take CNAM via ISDN. 
I have some experience with PRI providers, but I've never heard of 
one offering that service.

If you are a PRI provider in the lower 48 who takes CNAM and can pass 
that off to the PSTN, please get in touch with me off-list, 
especially if you handle SIP outbound to your gateways.  I may not 
buy service from you (or maybe I will!) but I'd be very interested in 
hearing what the particulars are about your offering so I can bring 
those elements to the table with my current providers.

This would be a big benefit for those of us trying to make The Phone 
System a little more dynamic than the sluggish monster that it 
currently is.  An SQL call and instant re-write for a name is a lot 
faster/better/more useful than sending a spreadsheet to the carrier 
every month.
