The following
table describes the properties that you can set to configure the SIP Service.
The first time you configure the SIP service on a Call Server, you must restart
the Call Server.

hostname that is an SRV type record instead of a standard DNS type record, this
field contains a fully qualified domain name that is configured on the DNS
server. Otherwise, the field contains an SRV configuration file.
For example, outbound calls made from CVP SIP service will be addressed to the URL of sip:<label>@<srvfqdn>. Redundant proxy
servers, for example, can route calls using such a configuration.

Dialed Number (DN)
Creates a Static
Proxy Route Configuration Table. You must create static routes if you do not
use a SIP Proxy Server. Before adding a local static route, you must enter a
value into both the Dialed Number (DN) and IP Address fields so that the local
static route is complete.
Click
Add to create a proxy route using the Dialed Number
(DN) and the IP address/Hostname entered above the
Add button. The newly created proxy route is added
to the list of proxy routes displayed in the box below the Add button.
Click Remove to delete the selected DN from the list box of Dialed Numbers.

Dialed Number
(DN) Patterns
Note
|
Enable "Override
System Dialed Number Pattern Configuration" to configure these values.
|
Patterns for sending calls
to the originator :
Dialed Number
(DN)
Creates a SIP Send
Back to Originator Lookup Table. Specify the DN patterns to match for sending
the call back to the originating gateway for VXML treatment. For the Unified
CVP branch model, use this field to automatically route incoming calls to the
Call Server from the gateway back to the originating gateway at the branch. For
information on the Unified CVP branch model, see
Planning
Guide for Cisco Unified Customer Voice Portal.
This setting
overrides sending the call to the outbound proxy or to any locally configured
static routes. It is also limited to calls from the IOS gateway SIP "User
Agent" because it checks the incoming invite's User Agent header value to
verify this information. If the label returned from ICM for the transfer
matches one of the patterns specified in this field, the call is routed to
sip:<label>@<host portion of from header of incoming
invite>.
Three types of DNs
work with Send To Originator: VRU label returned from ICM, Agent label returned
from ICM, and Ringtone label.
Send To Originator does not work for the error message DN because the inbound error message is played by survivability and
the post-route error message is a SIP REFER. (Send To Originator does not work for REFER transfers).
Note
|
For Send To Originator to work properly, the call must be TDM originated and have survivability configured on the pots dial
peer.
|
Patterns for RNA timeout on
outbound SIP calls:
- Dialed Number (DN)
Creates a Dialed
Number (DN) pattern outbound invite timeout using the DN and Timeout entered
above the Add button. Click
Add to add the newly created DN pattern outbound
invite timeout to the list displayed in the box below the Add button.
Click Remove to delete the selected DN pattern outbound invite timeout from the list.
Timeout (Seconds)
The number of
seconds the SIP Service waits for transferee to answer the phone or accept the
call.
If a selected termination (for either a new or transferred call) returns a connection failure or busy status, or if the target
rings for a period of time that exceeds the Call Server's ring-no-answer (RNA) timeout setting, the Call Server cancels the
transfer request and sends a transfer failure indication to Unified ICM. This scenario causes a router requery operation.
The Unified ICM routing script then recovers control and has the opportunity to select a different target or take other remedial
action.

Custom ringtone
patterns:
Dialed Number (DN)
Specify a custom
Dialed Number (DN) pattern. Click
Add to add the newly created DN pattern to the list
displayed in the box below the Add button.
To learn the DN configured on the gateway to play ringtone, run the sh run
command on the gateway and look for the dial peer that matches the incoming dialed number. See Ringtone Dialed Number Learning on Gateway Example.
Ringtone Media file name
The file name of
the ringtone to be played for the respective dialed number.
The ringtone media file must be saved to the VXML Gateway. See Transfer Script and Media File to Gateway for more information.
