In Cisco Unified Communications Manager Administration, use the Call Routing > SIP Route Pattern menu path to configure SIP route patterns.
Cisco Unified Communications Manager uses SIP route patterns to route or block both internal and external calls.
The domain name or IP address provides the basis for routing. The administrator can add domains, IP addresses, and IP network (subnet) addresses and associate them to SIP trunks (only). This method allows requests that are destined for these domains to be routed through particular SIP trunk interfaces.
Note
Because no default SIP route patterns exist in Cisco Unified Communications Manager, the administrator must set them up.
Note
Domain name examples: cisco.com, my-pc.cisco.com, *.com, rtp-ccm[1-5].cisco.com
Note
Valid characters for domain names: [, -, ., 0-9, A-Z, a-z, *, and ].
Note
IPv4 address examples: 172.18.201.119 or 172.18.201.119/32 (explicit IP host address); 172.18.0.0/16 (IP subnet); 172.18.201.18/21 (IP subnet).
Note
Valid characters for IP addresses: 0-9, ., and /
SIP route patterns configuration tips
Before you begin, ensure at least one SIP Profile and SIP trunk are configured before you can configure a SIP route pattern.
If the SIP route pattern is not in use, Cisco Unified Communications Manager deletes it. If it is in use, a message displays.
SIP route pattern settings
The following table describes the SIP route pattern settings.
Table 1 SIP route pattern settings
Field
Description
Pattern Definition
Pattern Usage
(Required) From the drop-down list, choose either Domain Routing or IP Address Routing.
IPv4 Pattern
(Required) Enter the domain, sub-domain, IPv4 address, or IP subnetwork address.
For Domain
Routing pattern usage, enter a
domain name IPv4 Pattern field that can resolve to an IPv4 address. The domain name
can contain the following characters: [, -, ., 0-9, A-Z, a-z, *, and ].
For IP
Address Routing pattern usage, enter an IPv4 address the IPv4 Pattern field that follows the format X.X.X.X, where X represents
a number between 0 and 255.
For the IP subnetwork address, in Classless Inter-Domain Routing (CIDR) notation, X.X.X.X/Y; where Y is the network prefix that denotes the number of bits in the address that will be the network address.
Tip
If the SIP trunk supports IPv6 or both IPv4 and IPv6 (dual-stack mode), configure the IPv6 Pattern in addition to the IPv4 pattern.
IPv6 Pattern
Cisco Unified Communications Manager uses SIP route patterns to route or block both internal and external calls. The IPv6 address in this field provides the basis for routing internal and external calls to SIP trunks that support IPv6.
Tip
If the SIP trunk supports IPv6 or both IPv4 and IPv6 (dual-stack mode), configure the IPv4 Pattern in addition to the IPv6 Pattern.
Description
For this optional entry, enter a description of the SIP Route Pattern. The description can include up to 50 characters in any language, but it cannot include double-quotes ("), percentage sign (%), ampersand (&), or angle brackets (<>).
Route Partition
If you want to use a partition to restrict access to the SIP route pattern, choose the desired partition from the drop-down list box. If you do not want to restrict access to the SIP route pattern, choose <None> for the partition.
You can configure the number of partitions that display in this drop-down list box by using the Max List Box Items enterprise parameter. If more than 250 partitions are specified by using the Max List Box Items enterprise parameter, the Find button displays next to the drop-down list box. Click the Find button to display the Select Partition window. Enter a partial partition name in the List items where Name contains field. Click the desired partition name in the list of partitions that displays in the Select item to use box and click Add Selected.
Note
To set the maximum list box items, choose System > Enterprise Parameters and choose CCMAdmin Parameters.
Make sure that the combination of SIP route pattern, route filter, and partition is unique within the Cisco Unified Communications Manager cluster.
SIP Trunk/Route List
(Required) From the drop-down list choose the SIP trunk or route list to which the SIP route pattern should be associated.
Click Edit to open the trunk or route list in the Trunk or Route List Configuration window.
Note
URI dialing is available over SIP trunks only. If you are using URI dialing and you select a route list from this drop-down list box, the route list must contain route groups with SIP trunks only.
Block Pattern
If you do not want this pattern to be used for routing calls, click the Block Pattern check box.
Calling Party Transformations
Use Calling Party's External Phone Mask
Check the check box if you want the full, external phone number to be used for calling line identification (CLID) on outgoing calls. You may also configure an External Phone Number Mask on all phone devices.
Calling Party Transformation Mask
Enter a transformation mask value. Valid entries include the digits 0 through 9 and the wildcard characters X, asterisk (*), and octothorpe (#). If this field is blank and the preceding field is not checked, no calling party transformation takes place. See topics related to calling party number transformations settings in the Cisco Unified Communications Manager System Guide for more information.
Prefix Digits (Outgoing Calls
Enter prefix digits in the Prefix Digits (Outgoing Calls) field. Valid entries include the digits 0 through 9 and the wildcard characters asterisk (*) and octothorpe (#).
Note
The appended prefix digit does not affect which directory numbers route to the assigned device.
Calling Line ID Presentation
Cisco Unified Communications Manager uses calling line ID presentation (CLIP/CLIR) as a supplementary service to allow or restrict the originating caller phone number on a call-by-call basis.
Choose whether you want the Cisco Unified Communications Manager to allow or restrict the display of the calling party phone number on the called party phone display for this SIP route pattern.
Choose Default if you do not want to change calling line ID presentation. Choose Allowed if you want Cisco Unified Communications Manager to allow the display of the calling number. Choose Restricted if you want Cisco Unified Communications Manager to block the display of the calling number.
For more information about this field, see topics related to calling party number transformations settings in the Cisco Unified Communications Manager System Guide.
Calling Line Name Presentation
Cisco Unified Communications Manager uses calling name presentation (CNIP/CNIR) as a supplementary service to allow or restrict the originating caller name on a call-by-call basis.
Choose whether you want the Cisco Unified Communications Manager to allow or restrict the display of the calling party name on the called party phone display for this SIP route pattern.
Choose Default if you do not want to change calling name presentation. Choose Allowed if you want Cisco Unified Communications Manager to display the calling name information. Choose Restricted if you want Cisco Unified Communications Manager to block the display of the calling name information.
For more information about this field, see topics related to calling party number transformations settings in the Cisco Unified Communications Manager System Guide.
Connected Party Transformations
Connected Line ID Presentation
Cisco Unified Communications Manager uses connected line ID presentation (COLP/COLR) as a supplementary service to allow or restrict the called party phone number on a call-by-call basis.
Choose whether you want Cisco Unified Communications Manager to allow or restrict the display of the connected party phone number on the calling party phone display for this SIP route pattern.
Choose Default if you do not want to change the connected line ID presentation. Choose Allowed if you want to display the connected party phone number. Choose Restricted if you want Cisco Unified Communications Manager to block the display of the connected party phone number.
If a call that originates from an IP phone on Cisco Unified Communications Manager encounters a device, such as a trunk, gateway, or route pattern, that has the Connected Line ID Presentation set to Default, the presentation value is automatically set to Allowed.
For more information about this field, see topics related to connected party presentation and restriction settings in the Cisco Unified Communications Manager System Guide.
Connected Line Name Presentation
Cisco Unified Communications Manager uses connected name presentation (CONP/CONR) as a supplementary service to allow or restrict the called party name on a call-by-call basis.
Choose whether you want Cisco Unified Communications Manager to allow or restrict the display of the connected party name on the calling party phone display for this SIP route pattern.
Choose Default if you do not want to change the connected name presentation. Choose Allowed if you want to display the connected party name. Choose Restricted if you want Cisco Unified Communications Manager to block the display of the connected party name.
