DTMF in VoIP connections

To send DTMF signals via VoIP, you must first define how key codes should be converted into and sent

as DTMF signals: as audible information via the speech channel or as a "SIP Info" message.

Ask your provider which type of DTMF transmission is supported.

Automatic negotiation of DTMF transmission

You have the following options:

¤ If you activate the option Ye s, the phone automatically attempts to set the suitable DTMF signal-

ling type for the current codec for each call.

¤ If you disable the No option, you can use the other options to specify the DTMF signalling type.

Counting missed and accepted calls

Missed and accepted calls for this VoIP account are recorded in the call lists for the phone if this func-

tion is activated.

Allowing or blocking call waiting

If you receive another incoming call during a call, this is indicated by Call Waiting by default. For each

¤ If you want to deactivate the function, select No.

Setting ring tones

You can set ring tones for each configured VoIP account. You can specify different ring tones for exter-

nal and internal calls as well as for group calls, if this information is available for incoming calls

(depending on the telephone system).
