Receiving SMS with SPA122 ATA

Good Day,

I use a SPA122 ATA (in bridge-mode behind a Netgear DGND3800B) for my VoIP comms.

The VoIP-evironment is provided by DT Deutsche Telekom in Germany.

Voice comms is not a problem.

From the analog telephone, that is connected to the ATA (Siemens Gigaset C470), I can send off SMS to anywhere. No Problem.

But when a SMS shall be received, then the phone just rings, the line is quiet, th call is terminated and some time later the provider calls with a voice-call and reads the message to me, because the phone did not take the SMS.

In the "Administration Guide Cisco SPA100 Series Phone Adapters" I could not finde any hint (or I did not understand it), about how to set the ATA for handing on incoming SMS to the phone.

The SPA122 is updated to firmware version 1.4.0 (001) May 27 2015

Hoping for a clever fix,

kind regards,

ADHamburg
