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 receive calls. When I connect my A400 handset to the same SPA112 port, I can receive calls (from SIP to analog) but cannot send (from analog to SIP) :
nothing shows at asterisk console.

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 mobile phone),
– 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 ?

Regards
