If the Outbound server address field is empty, the system behaves independently of the

selected mode, as with Outbound proxy mode = Never.

Outbound proxy port

This is the port number of the outbound proxy server, where the device should send all SIP

requests to (and where it in case of successful registration expects to receive requests from)

¤ Enter the communication port used by the outbound proxy.

Range: 1-65535; Default: 5060 (for UDP/TCP), 5061 (for TLS)

Outbound proxy port is empty and Outbound server address is a name:

The RFC3263 rules will be used to locate SIP servers and select them for load balancing and

redundancy.

Outbound proxy port is a fixed number:

The usage of DNS SRV records according to RFC3263 is blocked.

SIP SUBSCRIBE for Net-AM MWI

If activated a subscription is established for the purpose of receiving notifications about new

messages on the network mailbox.

¤ Enable/disable SIP subscription via the radio boxes next to SIP SUBSCRIBE for Net-AM MWI.

DTMF over VoIP Connections

DTMF signalling (Dual Tone Multi Frequency) is required, for example, for querying and control-

ling certain network mailboxes via digit codes, for controlling of automatic directory enquiries

or for remote operation of the local answering machine.

To send DTMF signals via VoIP, you must 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 VoIP provider which type of DTMF transmission it supports.

Automatic negotiation of DTMF transmission

¤ For each call, the phone attempts to set the appropriate DTMF signalling type for the codec

currently being negotiated: select Yes.

The system will use the transmission method matching best the received capabilities from

the peer based on the following priority order:

• send via RFC2833, if PT for telephone event is provided by the peer

• send via SIP INFO application/dtmf-relay, if SIP INFO method is supported by the peer

• send in-band audio

¤ Specify the DTMF signalling type explicitly: select No Select the send settings for DTMF

transmission:

Send settings of DTMF transmission

¤ Make the required settings for sending DTMF signals:

Audio or RFC 2833 DTMF signals are to be transmitted acoustically (in voice packets).

SIP Info DTMF signals are to be transmitted as code.
