[asterisk-users] SPA112: one analog phone works, not the other

After hours of testing, adding a comma into my FXS port dialplan made it.
This obviously relates to some timout handling but beside that, I
still have to understand why this seems mandatory.

> Hello,
> I'm preparing a setup before installing it within the next few days.
> In this setup, I'm using a SPA112 as an ATA for an analog phone.
> The target phone is a Gigaset A400 DECT handset.
> In my lab, I've got another A400 handset and an old Matracom 46 handset.
> When I connect my Matracom 46 handset to my SPA112, I can send and

> When I connect my A400 handset to the same SPA112 port, I can receive

> When connecting this A400 handset to my provider box (which also has
> an FXS port), I can successfully send and receive.
> From this, I conclude my A400 works but differently from my other handset.
> Basically, when dialing out with my A400, I'm observing this:
> - I dial my full number (eg 0123456789) then press Send key (as with a

> - then I hear a long dialing tone from the SPA112 (unplugging the
> cable between both cut this tone off),
> - then I hear dialing tones back (those are sent quite fast, one tone
> for each dialed digit),
> - then I hear a busy tone and nothing shows at asterisk console.
> Which SPA112 settings shall I change to get this A400 to work ?
> What would you suggest ?
