Session Initiation Protocol (SIP)
Почему SIP SIP становится все более распространенным протоколом Появляется все больше приложений поддерживающих SIP Клиенты требуют возможность подключения CallManager к сетям SIP. Для некоторых заказчиков это становится решающим критерием выбора оборудования. Поддержка протокола SIP в CallManager реализуется поэтапно. Первым этапом является поддержка SIP Trunk в версии 4.0.

IP Addr = 0.0.0.0 Call Forward (All / Busy / No Answer) SIP REDIRECTS (3xx) не приводит кновому анализу таблицы маршрутизации. Call Transfer (Blind / Consultation) инициированный SIP устройством не поддерживается.
DTMF Support Стандартом de facto для передачи DTMF по протоколу SIP является RFC2833. Как слендствие этого, требуется relay между out-ofband (SCCP) и in-band (RFC2833) методами передачи DTMF. Эта задача реализована с помощью MTP. RFC 2833 описываетдинамический тип payload для передачи DTMF сигналов. Отом какой тип payload будет использоваться для передачи DTMF CallManager и SIP устройство договариваются при установлении соединения иэта информация передается на MTP. Значение типа payload можно настроить в Service Parametes SIPTelephonyEventPayloadType. Значение по умолчанию -101.

Security Enhancements
Identity, Integrity, Privacy Identity: Means of authentication by which the authority to perform certain functions is granted. Having Encryption with out Identity and Integrity still leaves the security of the system at risk. Integrity: Maintains an authenticated link to guarantee that A packet originated from a trusted entity who shares your secret. That the message contents haven t changed in transit. Privacy: Encrypts the contents of a packet to ensure that it can t be read or interpreted by someone else.
Certificate Infrastructure Entities Certificate Authority (CA): Авторитетный источник цифровых документов (сертификатов), необходимых для однозначной идентификации устройств. Certificate: Цифровое удостоверение личности устройства, получившего этот сертификат. Certificate Authority Proxy Function (CAPF): По сути это локальный CA для выдачи сертификатов местного значения. CAPF поставляется вместе сcallmanager, также доступен на CCO. Certificate Trust List (CTL): Список устройств, с которыми разрешен обмен сертификатами Certificate Revocation List (CRL): Список отозванных сертификатов

Что такое Certificate Trust List (CTL) File? List of devices and credentials that a phone should trust on the network. Like a trusted third-party introduction Contains identity, public key and role information. IP-Телефоны должны доверять CCM, TFTP, CAPF. CTL-файл создается спомощью CTL Client на компьютере администратора системы. Файл подписывается спомощью USB etoken. USB etoken необходим для включения функций безопасности в CallManager ипокупается отдельно KEY-CCM-ADMIN-K9= IP-телефон получает файл по TFTP. Administrator s Security Token is a USB pluggable hardware that has a Cisco rooted Certificate.
CTL Provider Service Installed by CallManager installation. Interface using CCM Serviceability web pages. Must run CTL Provider service on every node where Cisco CallManager or Cisco TFTP service is activated.
CTL Client Wizard based windows application. Creates the Certificate Trust List (CTL file). Configures the CallManager ClusterSecurity Mode. Download and install the CTL Client on any windows 2000 ( or above) workstation/server that has a USB port. The CTL Client download is available in the CallManager Administration - Install Plugins web page.

Max Calls and CF Busy trigger Возможно до 10 одновременных вызовов. НО Если уже есть 5 вызовов иприходит шестой, сработает Busy Trigger и вызов будет переведен на Busy DN (CFB). Пользователь, однако, можетразместить еще 5 исходящих вызовов. Backward compatibility for legacy phones Scalability (Phone dependant) 7940, 7960, 7940 200 active calls per IP phone. Other phone models Not supported Future plans for up to 6 active calls per for for 7905 and 7912
Multiple Calls per Line Appearance 30 CF No Answer timeout Timer applies to all inbound calls not affected by the CF Busy trigger.
Conference List and Drop Any Party (ConfList) New softkey assignable to any IP phone supporting softkeys. Drop Last Party softkey remains separate assignable softkey for quick drop of last party. New ConfList Softkey Provides a list of participant s number and display name (if configured) in an ad-hoc conference. Conference controller can invoke this feature to view and remove any participant in the conference. Conference controller uses rocker key to scroll and highlight target party (or 7970 touch screen). Conference controller can drop the selected party with the Remove Softkey. Non conference controller can view list only.
Ad-hoc Conference Enhancements When only two participants remain in conference, conference will terminate and the two remaining participants are re-connected directly as a point to point call. Example: Mary, George, and Sam are in a Conference. Mary Hangs up George and Sam are in a point to point call. The Conference Bridge Resource is released.
Immediate Divert to voice mail (idivert) New idivert softkey. The Immediate Divert (ID) is a supplementary service of the Cisco CallManager. An idivert initiator can be either a calling party or called party. The ID diverts a call to a voice mailbox of the idivert initiator. A called party can invoke the idivert soft key in three call states (Call Alerting, Call Active, and Call on Hold). A calling party can invoke the idivert soft key in two call states (Call Active, and Call on Hold). If the ID diverts a call to a voice mailbox successfully, a diverted party will hear a voice mail greeting of the idivert initiator. Example: George Calls Sam Sam can t take call Diverts call to voice mail by hitting the idivert softkey Call goes to voice mail
Assign URL to Any Line Button Any line/speed dial button on selected XML-enabled IP phone can have assigned to it a URL. The URL can be associated with an XML service, such as MyFastDials. When the user presses the associated button, the URL is accessed and, in the case of XML services, the service is invoked. Example: MyFastDials applied to a line button can be pressed by a user, followed by the user pressing a two-digit code associated with a configured entry in the MyFastDials database. The call is immediately launched. This capability reduces the number of button presses to gain a desired action.
Configurable Call Forward Display Allows an administrator to configure the call information display of forwarded calls. Configuration is per line appearance. Option Type Original Dialed Number (ODN) Redirected Dialed Number (RDN) Calling Line ID (CLID) Calling Name ID (CNID) Default Enable Disable Enable Disable
Configurable Call Forward Display Dn=3101 George Dn=3102 Mary 3103 John Display on the target phone, dn=3106, when ODN, RDN, CLID and CNID are all selected Forward George [CNID] (3101) [CLID] For Mary 3102 [ODN] By John 3103 [RDN]
Configurable Call Forward Information If none of the four is configured, then only call duration is displayed. Applicable IP phones 791X, 794X, 796X, 797X SCCP-controlled software phone Selected Caveats: Information configured is displayed only on endpoints that are alerting Feature interaction shared lines, multiple phones configuration of this feature is per device. Therefore, devices that share a line appearance may support different configurations among two or more different endpoints
Call Distribution/ Hunt Groups
Hunt Group Enhancements Native CallManager support for hunting. Route list functionality expanded and renamed Route/Hunt List A Route list is an ordered list of object members including line groups and route groups. Can Contain Line Groups and Route Groups A Line Group can not follow a Line Group Hunt Pilot Number: A Hunt pilot number is associated with a Hunt list. A caller can reach someone by dialing the Hunt pilot number.
Hunt Group Enhancements Line Group - A collection of valid directory numbers. Ring no answer Reversion Timeout Call Distribution Algorithm Top Down. Longest Idle Broadcast (Ring every phone in line group) Circular Hunt Options: The system administrator can determine the action the Line Group will take after the following states: No Answer Busy Not Available The following options are available No Answer: When the line group receives a no answer from a member of the line group, the administrator can configure any of the following behavior: Default: Try next member, then try next group in hunt list. Try next member, but do not go to the next group. Skip Remaining members and go directly to next group. Stop Hunting. CTI Route points and ports are not allowed in Line Groups.
Hunt Group Enhancements Route group is the same as defined in CallManager 3.3 and earlier. There is no RNAR for route groups Performance enhancements 1500 Hunt Lists with 10 members each with broadcast hunting supported on MCS-7835-1400. Replaces Forwarding chains in Unity configuration. Put voicemail ports in a line group. For redundant Unity system, add a second line group. Assign No Answer Hunt option to Skip Remaining members and go directly to next group.

Multi-Level Precedence and Pre-emption
MLPP Overview Multi-Level Precedence and Preemption (MLPP) is a service which allows priority calls to be placed by properly validated users and if necessary preempt lower priority calls for the completion of the higher priority calls Precedence is the priority level associated with a call Preemption is the process of terminating lower precedence calls currently using the target device such that a call of higher precedence can be extended to or through the device Domain is determined by the subscription option of the originating user. Connections that are in use by calls in one domain can only be preempted by higher precedence calls in the same domain
