This topic describes the possible sources of URI calls and related configuration elements.
- Speed-dial buttons can be configured to place calls to destinations that are specified in URI format.
- URIs can be manually entered at supported phones such as the following:
- Cisco Unified IP Phones 8961, 9951, 9971
- Call list entries can be used at supported phones such as the following:
- Cisco Unified IP Phone 6900 Series; IP Phones 7942, 7963, 7945, 7965, 7975; Unified IP Phone 8900 and 9900 Series
- Calls are received via SIP trunks.
- If configured, the OTLD is added to URIs that do not have the @ symbol and host portion:
- Enterprise parameter is called Organization Top Level Domain and is unset by default.
- It allows URIs of the configured OTLD to be called by entering the user portion only.
Calls to directory URIs can be initiated from any Cisco IP phone by using a speed-dial button that is configured with a destination in URI format.
You can enter URIs manually at supported phones, including Cisco Unified IP Phones 8961, 9951, and 9971.
You can also place calls to call list entries in URI format at supported phones, including Cisco Unified IP Phones 7942, 7963, 7945, 7965, and 7975, and all Cisco Unified IP Phone 6900, 8900, and 9900 Series. When a call list entry is used to place an outbound call and the list entry is in URI format, then the call is placed to the corresponding directory URI.
Cisco Unified Communications Manager can also route calls to directory URIs when the calls have been received through a SIP trunk.
When a dialed URI does not include the @ symbol followed by a host portion (that is, only the user portion is dialed), then the call fails unless you configured the enterprise parameter Organization Top Level Domain. By default, the OTLD is unset. If the OTLD is set, the @ symbol followed by the configured OTLD are appended to the dialed URI.
Setting the OTLD allows users to place calls to URIs by entering only the user portion.
