Configuring Call Hold/Resume for Shared Lines
First Published: August 1, 2008
This chapter describes the Call Hold/Resume for Shared Lines for SCCP Analog Ports feature for analog phones that are connected to Foreign Exchange Station (FXS) ports on a a Cisco Integrated Services Router (ISR) or Cisco VG224 Analog Phone Gateway. This feature is supported for analog endpoints that are controlled by Cisco Unified Communications Manager only.

Prerequisites for Call Hold/Resume for Shared Lines for SCCP Analog Ports
- Cisco IOS Release 12.4(20)YA or a later release.
- The Cisco voice gateway must be set up and configured for operation. For information, see the appropriate Cisco configuration documentation.
- The analog FXS voice ports are set up and configured for operation. For information, see the Cisco IOS Voice Port Configuration Guide.
- SCCP and the SCCP telephony control (STC) application is enabled on the Cisco voice gateway. For configuration information, see the “Configuring FXS Ports for Basic Calls” section.
- SCCP supplementary features are enabled on the Cisco voice gateway. See the “Configuring Supplementary Features” section.
Restrictions for Call Hold/Resume for Shared Lines for SCCP Analog Ports
- This feature is not supported for analog SCCP endpoints in Cisco Unified Communications Manager Express (Cisco Unified CME).
- This feature is not supported for FXS ports on a Cisco Unified 500 Series platform.
- If Call Hold/Resume for Shared Lines is configured and a call is connected, the analog phone user must press a second hookflash to get a feature tone and then dial a Feature Access Code (FAC) to invoke call transfer, call waiting, or call conference features.
Information About Call Hold/Resume for Shared Lines for SCCP Analog Ports
To enable SCCP supplementary features on analog phones connected to FXS ports on a Cisco voice gateway, you should understand the following concepts:
Feature Summary
Table 1 contains information about the Call Hold/Resume for Shared Lines for SCCP Analog Ports feature, along with information about how to configure support this feature in your Cisco call-control system.

Enables user on an analog SCCP phone that shares a line with an IP phone to hold and resume an active call by pressing hookflash. |
During an active call, an analog phone user on a shared line presses hookflash to place an active call on hold. The analog phone user hears a dial tone and can place a call, go on-hook, or press hookflash again to resume the call. The held call can be resumed by any phone on the shared line as follows: |
For feature information, see the “Making and Receiving Multiple Calls Per Directory Number” section of the “Understanding Directory Numbers” chapter under “Dial Plan Architecture” in the Cisco Unified Communications Manager System Guide. This feature is enabled in Cisco Unified Communications Manager by default. No feature-specific configuration is required to support Hold/Resume on Shared Lines. This feature is not supported for analog endpoints in Cisco Unified CME. |
Call Hold/Resume for Shared Lines for SCCP Analog Ports
Call Hold/Resume for SCCP analog ports that share a directory number with one or more other phones in Cisco Unified Communications Manager is supported in Cisco IOS Release 12.4(20)YA and later releases. This feature is supported only on analog SCCP phones connected to FXS ports on which Hold/Resume is configured.
During an active call, an analog phone user on a shared line presses hookflash to place the call on hold to answer an incoming call or to access a dialtone if a line is available. To resume the held call, the analog phone user presses hookflash a second time. To resume the held call on another phone on the shared line, any analog phone on the shared line goes off-hook or any IP phone on the shared line goes off-hook and the user presses Resume.
This feature also allows the analog phone user to place a new call while the shared line is in use. The new call is restricted to basic calling; supplementary services is not supported for the new call from an analog SCCP phone on an in-use shared line.
The default maximum number of calls supported on analog phones on a shared line is two. When an analog phone on a shared line is off-hook, it is in an active-call state. If two analog phones on a shared line are off-hook, other analog phones on the shared line cannot access a dialtone nor receive incoming calls. If an analog phone user presses hookflash while the shared line is in-use by two analog phones, the user hears a fast busy tone. Number of calls on analog phones and on IP phones on the same shared line are counted separately and the maximum-number configuration on one does not affect the other.
To configure Hold/Resume for Shared Lines, see the “How to Configure Call Hold/Resume for Shared Lines for SCCP Analog Ports” section.
