Picking Up Callerid Info

[Guest RobG]

With Verizon POTS (plain old telephone service) in New Jersey for sure; and very probably for the rest of North America:

 

The CallerID data is passed from the central office to the customer's phone (VoiceGuide) between the first and second rings. This means, if you want to capture that info, you need to edit C:\Program Files\VoiceGuide\data\Config.xml to set the number of RingsBeforeAnswer to at least 2 rings.

 

<RingsBeforeAnswer>2</RingsBeforeAnswer>

 

I have no idea how it is handled in ISDN, T-1, or any other service. Then again, if you are writing routines for these, you're probably not a newbie anyway

 

Enjoy!
