[asterisk-users] how to transfer calls when analog phone hasnotransfer button

[Doug Crompton]

Well it would be interesting to know what FXS device you are using to
connect the analog phones. I use an SPA-3000 fxo/fxs and with it you could
bypass Asterisk and connect the FXO to FXS or dial directly if it were so
configured, so reinvite would work but wwould probably not be desired but
that is not the question...

I am using the SPA-3000 as both an FXO (connection to telco) and FXS
(connection to my house analog phones) with Asterisk in between. I have
said this before on here but I will say it again. With the SPA-3000 you
cannot have analog phone feature keys, transfer etc. AND still be able to
use DTMF for control outside of the dialplan.

If you want feature key control then you would use rfc2833 DTMF, if you
want to be able to use DTMF incoming or outgoing for control then you must
use inband DTMF. It is either/or.

My choice was to use inband and not have features selected for the analog
phones. To often I would use these phines with banking or on incoming to
control voicemail functions so I wanted that capability.

In that case a hook flash works fine. If you have never done it just flash
the hook for a second (or use the flash key on the phone) and you will get
another dialtone. Then you can call another party, tell them you have a
call to transfer and hangup or click again and bring them in as a
conference.
