EXHAUSTIVE search, I'm still in the dark.
Any help would be IMMENSELY appreciated.
1) How can I go about getting an application such as Phonetray
(http://phonetray.traysoft.com/freecalleridsoftware_features.htm) to
work with Vonage WITHOUT having a dialup modem?
In other words, is there ANY way to use my existing RT31P2 router to
display/speak when I have an incoming call?
2) I would like to run a program every time I receive an incoming
call. I thought I would be able to do this using SIP to detect the
caller ID and some sort of batch script but am very much lost as to
how to do it but can't imagine it would be that difficult.
I know this MUST be possible to do because the webpage has caller ID
there. How are they doing it? Why is it that EVERYTHING I have found
thus far tells me I must use a 56K modem??
From what I understand, Phonetray reads the Caller ID information from
the POTS telephone line, where it's sent while the telephone is |
ringing; the dialup modem is connected to the line, and can read and
decode such information to pass it to the Phonetray application. As
long as you have an ATA that converts VoIP calls (e.g., SIP INVITE
messages) into rings + caller ID sent to a conventional analog
telephone set, _and_ you connect the line from the ATA to the "line"
connector of the modem and the "phone" connector to the telephone set,
Phonetray should work as advertised. In fact, Phonetray won't even
_know_ that the call originally arrived from the Internet and was
converted by the ATA before being sent to the modem.
Of course, un theory one could also get the Caller ID directly from the
SIP messages arriving from the Internet: but that would require a way
to make those SIP messages available to the software replacing
Phonetray (and, of course, would also require the existence of such
software!). But the RT31P2 captures the SIP messages and uses them
inside its built-in ATA, without ever giving the PC a chance of seeing
them on its ethernet interface. This means that also the caller ID
information never arrives to the computer, and therefore can't be used
by any piece of software running there.
