[Freeswitch-users] Handling call forward activate / deactivate through FreeTDM using Sangoma A200

Yes, telco returns the confirmation tone (two small tones) if we connect a
standard phone directly on the line. Thats how my customer is currently
activating / deactivating CFW.
The solution you provide is nice but is more a workaround than a solution as
it could lead to failures if the telco is, for some reason, not returning
the confirmation tone. That would create confusion at my customer.
Nevertheless, you brought a good idea as I could use mod_spandsp to detect
those tones and then offer such tone back to my customer. Ill pursue this
path once I get Sangoma to explain why it takes almost 10 seconds to connect
the FXO port on the POTS line and sends the digits.

Are you sure that the telco sends back dial tone? One thing you can do is
use the ftdm-trace command to capture the raw audio coming in on the port.
Another thing you can do is just have *72 go to a play_and_get_digits app
that plays dialtone to the user and collects digits. (Look in features.xml
for an example of this, in the "dx" extension if memory serves.) From there
just bridge to *72 + pause + dialed digits from PAGD. For *73 you can just
bridge to *73 since you don't normally need to dial any digits.

Hello FS users,
I have Freeswitch (1.3.13) using a Sangoma A200 card with 2 FXO. I am using
FreeTDM and inbound/outbound calls are going through. One of the POTS line
has call forwarding feature so my customer wants to have the ability to dial
*72 / *73 and get proper dialtone back from the phone company so he can
activate or deactivate CFW.
While the call is marked as answer in the log, I dont hear the dialtone
back so unsure if it works or not. This is the dialplan I used:
<extension name="CFW Handler">
<condition field="destination_number" expression="^(\*72|\*73)$">
<action application="bridge" data="freetdm/FXO/1/$1"/>
Is there a better way or a good way of doing this?
