this header. If P-Asserted-Identity is selected and the Privacy header
is set to 'id', the calling number is assumed restricted.
CLI: src-hdr-4-called-nb
[SelectSourceHeaderFor
CalledNumber]
Determines the SIP header used for obtaining the called number
(destination) for IP-to-Tel calls.
[0] Request-URI header = (Default) Obtains the destination number
from the user part of the Request-URI.
[1] To header = Obtains the destination number from the user part of
the To header.
[2] P-Called-Party-ID header = Obtains the destination number from
the P-Called-Party-ID header.
Web/EMS: Forking
Handling Mode
CLI: forking-handling
[ForkingHandlingMode]
Determines how the device handles the receipt of multiple SIP 18x
forking responses for Tel-to-IP calls. The forking 18x response is the
response with a different SIP to-tag than the previous 18x response.
These responses are typically generated (initiated) by Proxy /
Application servers that perform call forking, sending the device's
originating INVITE (received from SIP clients) to several destinations,
using the same CallID.
[0] Parallel handling = (Default) If SIP 18x with SDP is received, the
device opens a voice stream according to the received SDP and
disregards any subsequently received 18x forking responses (with or
without SDP). If the first response is 180 without SDP, the device
responds according to the PlayRBTone2TEL parameter and
disregards the subsequent forking 18x responses.
[1] Sequential handling = If 18x with SDP is received, the device
opens a voice stream according to the received SDP. The device re-
opens the stream according to subsequently received 18x responses
with SDP, or plays a ringback tone if 180 response without SDP is
received. If the first received response is 180 without SDP, the
device responds according to the PlayRBTone2TEL parameter and
processes the subsequent 18x forking responses.
Note: Regardless of this parameter setting, once a SIP 200 OK
response is received, the device uses the RTP information and re-
opens the voice stream, if necessary.
Web: Forking Timeout
CLI: forking-timeout
[ForkingTimeOut]
Defines the timeout (in seconds) that is started after the first SIP 2xx
response has been received for a User Agent when a Proxy server
performs call forking (Proxy server forwards the INVITE to multiple SIP
User Agents). The device sends a SIP ACK and BYE in response to
any additional SIP 2xx received from the Proxy within this timeout. Once
this timeout elapses, the device ignores any subsequent SIP 2xx.
The number of supported forking calls per channel is 20. In other words,
for an INVITE message, the device can receive up to 20 forking
responses from the Proxy server.
The valid range is 0 to 30. The default is 30.
Web: Tel2IP Call Forking
Mode
CLI: tel2ip-call-forking-
mode
[Tel2IPCallForkingMode
]
Enables Tel-to-IP call forking, whereby a Tel call can be routed to
multiple IP destinations.
[0] Disable (default)
[1] Enable
Note: Once enabled, routing rules must be assigned Forking Groups in
the Outbound IP Routing table.
Web/EMS: Enable
Reason Header
Enables the usage of the SIP Reason header.
[0] Disable
