"The best business telephones in the world."

Hello

we have the Snom D715, the outgoing calls work fine, each party can hear the other.

As soon someone calls us we can´t hear them but they can hear us..

is there some solution? thx

Hello. If you refer to RTP/SAVT option it´s already OFF

Do oyu have any other suggestions? Thank you very much

Thank you again. I´ve disabled the RTP encryption but again the same. When I call from the snom everything is fine but when someone calls me to Snom then I can´t hear them.

The sip provider is sipgate.de if it does make any difference to you. thx
