Description
To define the Dual-tone multi-frequency (DTMF) signalling method. The options
are:
• RFC 4733. With this method, DTMF signals are carried in RTP packets by
using a separate RTP payload format. It is set by default.
• SIP Info. With this method, the DTMF signals are sent as SIP requests. The
SIP switch creates the tones if the call is transferred to the PSTN.
• In-band. With this method, the phone itself generates the tones and sends
them in the voice frequency band.
Important:
Use RFC 4733 or SIP Info as the preferred methods because they are
more consistent with other tones available. Switch to In-band only when
your SIP server does not support other DTMF signalling methods.
Note:
When RFC 4733 is configured as the DTMF method on B199 Conference
Phone, but other party does not accept such method, the phone falls back
into using the In-band method.
To specify the type of audio traffic. By default it is 101.
To enable or disable remote port forwarding. By default, the setting is disabled.
To set a time-related mechanism to disconnect the sessions that the phone
establishes. The options are:
• Disabled.
• Optional. This is the default setting.
• Mandatory
To specify the session expiration time in seconds. The default setting is 1800
seconds.
To specify the IP address of the outbound proxy, if available.
To enable or disable provision of key information for troubleshooting. By
default, the setting is disabled.
To enable or disable storing the IP address from the response of the register
request. If a change is detected, the phone unregisters the available SIP URI
(contact), and updates it with the new address.
By default, the setting is in the enabled state.
To enable or disable the SIP Replaces header.
