indeed, in my search for alternatives to FXO I learned the following:

* Bezekint (074 service) indeed uses SIP, but they are really new at
this, and don't know about the protocol details. However Nir Simyonovich
hinted he is one of their suppliers, and Asterisk is part of the
infrastructure, and so interfacing it with a phone switch should be
smooth. (I'm assuming that I can have my Asterisk behave like a SIP
client for incoming calls, I don't know yet how I can ask them to take
over handling multiple calls myself at MY end instead of having their
PBX do it, they promissed they will get back to me)

* 012 (072 service) also has a service or two they may be able to offer
me, but they two were not too clear about the details. I have a meeting
with them next week.

* Hot (077 service) is using a cable link protocol, directly on DOCSYS,
therefore nothing like SIP or Asterisk compliance. you have to use their
ATA. At the very least I would have expected this little detail to mean
that the ATA takes on a separate slice of bandwidth from the Internet
connection and therefore can't be squelched by heavy downloading, but no
such luck. Nir tells me all the above solutions suffer from jitter, and
this one is no exception.

Finally, not VoIP, but a cheaper hookup, bezeq would not upgrade POTS to
ISDN anymore, but you order them starting at 930 NIS for the most basic
NT (S-bus only) or 1460 NIS for an NT with two FXS ports. Even If your
BRI card speaks U-bus directly, you STILL have to get the NT. shmucks.
However I think a BRI card should be cheaper and allow smarter options
than FXO to a POTS.

I'd like to take this opportunity to thank all the people who helped me
with pointers this week! Unfortunately I was told today by my client
that due to cash shortage he's putting this Asterisk project on hold.
I'm all enthused though (in the schwoong, as they say in Germany) and
looking for a new vict^H^H^H^Hclient to try Asterisk on... anyone? :)
