asterisk users - Mar 2006 - Connecting a Grandstream Handytone 486 to Asterisk

Hello,

I bought a Grandstream Handytone 486 to forward incoming calls from our old
analogue PBX to the asterisk server.

My first test was connecting an analogue phone to the Handytone and calling a
sip phone - worked.
Now I used the same cable to connect the line port of the Handytone to the
analogue pbx. When I call the number of the analogue PBX I
hear a clicking inside, but the call doesn't get forwarded to asterisk. I
used tcpdump to see whether the Handytone sends
data packages at all, but it doesn't.
Unfortunately the Grandstream support didn't answer my support request. Does
someone of you know how to connect the Handytone to the asterisk server, maybe I
need a special cable?

Thanks for any hints,

Ralf

hi Ralf,
AFAIK, the 486 CANNOT do what you want it to do.
you need a call thru functionality and this can be achieved only with 488 .
then you conect the line to the old analog PBX extension and any call coming
to this extension will enter the Asterisk as a call from a SIP extension.

i hope i helped you with some hints

good luck,Mickey

Is the device an FXO or FXS. From what it seems (that
you are connecting a phone to it) that it is an FXS.
This will not allow inbound calls from a PBX. You need
an FXO.
