© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Third-Party Phone Configuration Cisco Unified CallManager Release 5.0 supports RFC compliant SIP phones from third-party companies. Two categories of third-party SIP phones in Cisco Unified CallManager: –Basic supports one line and consumes three license units. –Advanced supports up to eight lines and video, and consumes six license units. Third-party SIP phones do not send their MAC address to Cisco Unified CallManager in their REGISTER message. Therefore, you must use Digest Authentication with third-party SIP phones. Configuration is performed on Cisco Unified CallManager and on the phone itself.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Third-Party Phone Configuration (Cont.) 4. Configure the authorization ID on the phone and ensure that the phone is enabled to use it. block The proxy address should be the Cisco Unified CallManager IP address or name. If the phone uses a directory number instead of an authorization ID, the User ID in the End User Configuration in Cisco Unified CallManager must also be the directory number.

User presses Dial softkey 3. Phone sends digits and call is placed User experience is like that of an SCCP phone: 1. User enters digits into keypad 2. When digits match a valid pattern, the phone sends digits automatically and call is placed without user having to press the Dial softkey Cisco SIP Phone with Dial Rules or KPML Third-Party or Cisco SIP Phone Without SIP Dial Rules or KPML KPML enables digit-by-digit dialing. Dial rules tell the Cisco SIP IP Phone when enough digits are collected before call processing takes place. Both enable a user to dial a destination without pressing the Dial key.

CIPT1 v Dial Rules and KPML Support in Cisco Unified CallManager Release 5.0 Dial rules support in Cisco Unified CallManager Release 5.0: –Local dial rules are called SIP Dial Rules and are configured in Cisco Unified CallManager Release 5.0. –Cisco 8.0 SIP phones with firmware version 8.0 download dial rules from TFTP server. –Due to syntax differences, one set of dial rules must be defined for Cisco IP Phone 7940, 7960, 7911, 7941, 7961, and 797x models, while another set for Cisco IP Phone 7905 and 7912 models. KPML support in Cisco Unified CallManager Release 5.0: –KMPL is implemented as per draft-ietf-sipping-kpml.draft-ietf-sipping-kpml –KMPL is only supported on Cisco IP Phone 7911, 7941, 7961, and 797x models; Cisco IP Phone 7905, 7912, 7940, and 7960 models must use local dial rules. –If the third-party SIP phone does not support KPML, you must use locally-defined digit maps.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Dial Rules Configuration Overview Dial rules enable the Cisco SIP phone to know when enough digits are collected before call processing takes place. Dial rule syntax is slightly different on Cisco IP Phone 7905/12 models than it is on Cisco IP Phone 797x, 7941, 7961, 7911 models. Dial rule syntax varies considerably on third-Party SIP phones, and some do not support dial rules.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v SIP Phone Dial Rules Configuration Sequence 1. The administrator configures the SIP dial rules and associates them with the SIP phone. 2. Cisco Unified CallManager notifies the TFTP server of the change. 3. The TFTP server rebuilds the dial rules configuration file of the phone. 4. The administrator resets or restarts the phone and the dial rules file is downloaded to the phone. TFTP Server Cisco IP Phone _DialRules DR7970_DialRules.xml Cisco Unified CallManager

CIPT1 v Summary Cisco Unified CallManager supports SIP on Cisco IP Phone 7970/71, 7960/61, 7940/41, 7911, and 7905/12 models as well as selected third-party phones. Cisco Unified CallManager integrates native SIP (RFC 2833) and SIMPLE support on both line-side and trunk-side interfaces for a variety of endpoints, gateways, and applications. External SIP proxy server is no longer required. DTMF and KPML can be used for digit collection when dialing on a SIP phone. Cisco Unified CallManager collects digits either one at a time, or, more efficiently, using SIP dial rules. Provisioning a Cisco SIP phone is just like provisioning a Cisco IP phone controlled by SCCP.

© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Summary (Cont.) SIP profile provides SIP-specific configuration information for SIP phones and SIP trunks. Conversion of a Cisco SCCP phone to a Cisco SIP phone is done either by manual replacement of TFTP configuration files, or by using Cisco Unified CallManager BAT. Third-party SIP phones do not send their MAC address at boot time; all the configuration is performed on Cisco Unified CallManager and on the phone itself. When you configure a SIP dial plan and associate it with a Cisco SIP phone, TFTP server builds a new set of files for the Cisco SIP phone. Once the you initiate the phone reset, the new dial rules are applied to the phone.
