There is also the ObiHai OBi202 with an OBiLine, which provides an FXO
port remoted over SIP.  (I am not sure if this is discontinued.)

How about something like the ancient Ethernet based Sipura 3000?

[asterisk-users] USB dahdi fxo ?

[sean darcy]

I'm moving asterisk to a laptop, so can't use the dahdi board. Is there 
any supported USB dahdi device ? I see the Sangoma USBfxo device, but 
the dahdi driver no longer supports it. Anything else ?

    same => n,Gosub(s-${DIALSTATUS},s,1)

[check_for_direct]

;**

exten =>

;
;* If the contents of speed.phone is blank, assume that it
;* is not programmed and force the call to use the IVR to
;* prove they are not an automated call.

 same => n,GotoIf($["${speed.phone}" != "" ]?3:ivr_menu,s,1)
 same => n,NoOP(${speed.name} is on the approved list)
 same => n,Return()

Re: [asterisk-users] Block Spam Calls

[Jeff LaCoursiere]

Mind posting your dialplan code?  I was thinking the same thing - very 
much like an old spam control program I used to use whose name now 
escapes me.  First time senders would have to respond to an auto-reply, 
then were added to a whitelist.


This would be a great FreeBSD module...

Cheers,

I do something similar for calls without caller ID, but I was still
getting robocalls with spoofed caller ID. I have now changed the dialplan
slightly so that the first time people call they are asked to dial 1.
After the first call, they are added to a known caller list and get
straight through, and any robocalls at that point are blacklisted
manually. I have found that most robocallers spoof the Caller ID so
rarely call from the same number twice. It means that legitimate
callers who cannot dial 1 just have to dial again to get through to
the phones - there is a recorded message telling them to dial 1 or
call back. I haven't had a robocall since!

The hardest thing about this was extracting all the numbers of
previous callers from the CDR and adding it to the Previous_Callers
AstDB for the lookup. I didn't want to make existing callers go through
the initial learning process.
