This section provides information about how the IP DECT feature interacts with other features on the system. Use this information to ensure that you receive the maximum benefits of IP DECT in any feature configuration.

Abbreviated Dialing

The IP DECT station uses the Abbreviated Dialing List feature access codes to dial the station, group and system abbreviated dial lists (as administered per station).

Analog – Generic

The IP DECT station can be treated as an analog station in terms of feature interactions.

Analog Disconnect

Communication Manager supports the Analog Disconnect with dial tone after 10 seconds feature for IP DECT.

Announcement

The IP DECT station initiates the Announcement feature to record an announcement by dialing the Announcement feature access code.

Attendant

The IP DECT station reaches an Attendant by dialing the Attendant feature access code.

Automatic Alternate Routing

The IP DECT station initiates an Automatic Alternate Routing (AAR) call by dialing the AAR feature access code.

Automatic Call Back

The IP DECT station initiates or receives an Automatic Call Back (ACB) call by dialing the ACB feature access code.

Automatic Call Distribution

The IP DECT station uses the various Automatic Call Distribution (ACD) features. The ACD features can be activated by dialing the following ACD feature access codes:
  • After Call Work
  • Assist
  • Auto-In
  • Aux Work
  • Login
  • Logout
  • Manual-in
  • Service Observing Listen Only
  • Service Observing Listen/Talk
  • Service Observing No Talk
  • Add Agent Skill
  • Remove Agent Skill
  • Remote Logout of Agent
These features do not provide ACD-related display update to the IP DECT telephones. If the IP DECT telephone is out of a coverage area, is turned off, or has a low battery, Communication Manager has no knowledge in these scenarios. As a result, Communication Manager cannot accept service from the IP DECT telephones.

Automatic Route Selection

The IP DECT station initiates an Automatic Route Selection (ARS) call by dialing the ARS feature access code.

Bridged appearance

The IP DECT station can be an analog-bridged appearance on another station, or can be administered as a bridged appearance (analog or regular) of a station.
The bridge appearance status LEDs reflects the status of the IP DECT station. The IP DECT station can bridge calls as in any other bridge of a directly connected wired station. The MWI of the station can be set to the principal extension or the bridged extension.
Note:
If IP DECT station is a bridged appearance of a station and already in a call, no call waiting tone is sent to the handset and no display update is visible for the second incoming call.

Call Admission Control

The IP DECT configuration supports Call Admission Control bandwidth limits between any pair of IP network regions.

Call Coverage

When coverage is administered for the IP DECT station, if the station (Ring No Answer, Subscriber Absent, or Busy) does not answer the call, the X-mobile station sends calls to coverage. The IP DECT station can be a coverage point and supports the IP DECT reject feature.
If the IP DECT station is out of system, silent charging, or the user presses the reject button, IP DECT system drops the alerting call. If the station has no answer coverage, the call immediately goes to coverage. If the station is a coverage point, the call immediately progress to the next coverage point. In both the cases, the call does not drop and the caller continues to receive ringback.
If the IP DECT station is a bridge, the reject button will have the above affect. The coverage path used is that of the principal, not the IP DECT station.

Call forwarding

The IP DECT station can activate and deactivate all options for call forwarding, extended call forwarding, and enhanced call forwarding using the various call forwarding feature access codes. The remote station state can be used to determine if call forwarding criteria is met. If the remote station is busy, the criteria is met. If the remote station does not answer the call, Ring No Answer criteria is met. The IP DECT can be the station that is call forwarded to and supports the IP DECT reject feature.
If the IP DECT is out of system, silent charging, or the user presses the reject button, IP DECT system drops the alerting call. If the station has no answer forwarding, the call immediately forwards. Coverage after forwarding may still take place. In both the cases, the call does not drop and the caller can continue to receive ringback.
If the IP DECT station is a bridge, the reject button will have the above effect. The forwarding used is that of the principal, not the IP DECT station.

Call Park or Answer Back

The IP DECT station can park its current call after a flash operation by using the Call Park feature access code. The IP DECT station can answer a parked call by using the Answer Back feature access code.

Call Pickup

The IP DECT station can be in a Call Pickup Group and use the Call Pickup, Directed Call Pickup, Directed Group Call Pickup, and Extended Group Call Pickup feature access codes.
Pickup groups containing IP DECT can be in the Extended Groups. As a result, IP DECT handsets can pickup calls from other pickup groups in the same way the analog-wired stations can.

Call Shuttle

If the IP DECT feature is administered as a call shuttle, the station is alerted through call waiting tone when another incoming call arrives for it while the IP DECT station is on a call. The IP DECT station can accept the second call automatically through a flash operation. This puts the first party on soft hold. Subsequent flash operations shuttle between the second and first parties result in clearing the current call and recalling the IP DECT station to attempt to reconnect the soft held party.

Call Vectoring

The IP DECT station can change the values of variables used in the Call Vectoring feature. The values can be changed by dialing the following Call Vectoring or Prompting feature access codes:
  • Converse Data Return Code
  • Vector Variables 1-9

Call Waiting

When a call arrives for the IP DECT station and Call Waiting is administered, Call Waiting Tone is applied as defined by the operations of Communication Manager.

CAS Remote Hold or Answer Hold-Unhold

The IP DECT station uses the CAS Remote Hold or Answer Hold-Unhold feature access code to put a call on hard hold and to retrieve a call from hard hold.

Codec selection

Communication Manager use the codecs administered on the IP Codec Set screen corresponding to the IP Network Region for the H.323 signaling group pointing to IP DECT system and negotiate the codecs to use with IP DECT system as in H.323.

Conference

The flash operation is sent by pressing the R-Key on the IP DECT handset. If the IP DECT initiates a second call by a previous flash operation and the third party answer the second call, then a flash operation conference all three parties. If the IP DECT initiates another flash operation, the IP DECT drops the last added party. If the IP DECT telephone drops from the conference and hence is now idle, the remaining parties on the conference call stay connected.
To activate a conference you need to enable the Allow Conference via Flash field on the Feature-Related System Parameters screen, otherwise the flash operation (R-key) puts the active call on hold and brings up the held call to active state.

Connection Failover with Master Base Station

Upon a connection failover during an ongoing IP DECT to IP DECT call, the secondary base station takes over. However the very first call made from either of the IP DECT extension shall not succeed. From then on, any further call from either of the IP DECT will be successful.

Connection Preservation for Branch Gateways Failover and Failback

Connection preservation for Branch Gateways in Failover and Failback does not support H.323 trunks. As a result, this feature does not work for IP DECT configurations.
