PSTN Call Transfer Settings
Some Call Transfer options can be configured in the Blind Call Transfer section and in the Supervised Call
Transfer section.
Number format
(outbound): This parameter determines the shortest format allowed in calls sent out by this interface. You may
modify this parameter only if you selected a dialplan from the drop down menu. The following options
are available:
Unchanged : The number signaled in the SIP message will be used unchanged for dialing.
International number : The number is always converted to an international number, including
country and area code.
National number : The number is converted to a national number unless it is an international number
with a different country code.
Extension: The number is reduced as possible. An internal number is reduced to its extension only.
For more information about number formats, see How Numbers Are Processed on page 63.
Encoding
(outbound): Determines if numbers in calls sent out by this interface should either be encoded as unknown number
with national or international prefix digits, or as national or international number with type flags.
Default
numbering plan: Change this setting only if the PBX rejects calls from the Diva SIPcontrol software despite the dialed
number being correct. This might occur if, for example, the signaled numbering plan is not supported.
Default
presentation
indicator: If no presentation is specified via address rewriting, the presentation indicator to set on calling party

channel is freed. The transfer may be announced or unannounced.
With consultation call via tromboning : The call transfer is emulated. Two B-channels are
blocked during the call transfer.
Complete transfer
in state: The blind call transfer is typically handled via an implicit call to the transfer destination. Once this
call reaches the state specified via the option
Invoke Call Transfer in state , the call transfer is
completed. Default setting is Connected . If the calling party should hear the ring back tone from
the transfer destination, this parameter must be set to Proceeding or Alerting .
Use same channel
