52.28.1 Dial

Dials a phone number and sets up a voice call (circuit-switched or VoIP). Can be used during a voice call to add a third party to the call to produce a three-way conference call. (See section"Conference Calls" for more information.)
You may instruct the device to retry the call if the call setup fails. The retry behavior is governed by the On Failure property; see section "Failure Handling Section".
The call duration is specified:

in a subsequent "Voice Quality" or " AQM Measurement" activity, if voice quality is measured;

otherwise, most conveniently by means of a subsequent "Wait" activity.

Configuration property:

Call Type:

Default: The type of call the device will make (CS or VoIP) is determined by a setting in the device, or by its capabilities.

VoIP UE: VoIP call using an on-device VoIP client.

VoIP PC: VoIP call using the VoIP client built into TEMS Investigation. Regarding this, see also section "How to Set Up PC Client Based VoIP Testing".

Phone Number: The complete phone number to call, including country code. For audio quality measurement, enter the number to the other call party; see chapters "AQM with ACU R2"–"AQM for VoIP". Valid characters are: +, #, *, 0, ..., 9, and p (for pause).

Phone Numbers to connected devices can be resolved automatically during script execution. To use this function, click on the three dots in the Phone Number field and select the device that should receive the call. The Phone Number field will then be filled with !!EQ1.PhoneNumber!! (the device number: EQ1 in this case, depends on selected device).

Codec: (Appears for certain VoIP clients) Voice codec, one of: G.711 A-law, G.711 μ-law, AMR-WB, AMR-NB, or EVRC-B. "Default" is the client's default codec, which means the one last used. If the VoIP client does not support codec selection, it always uses the default codec.

For certain codecs, this additional field appears:

Codec Rate: Voice codec bit rate.

Multi-party calling:

Disabled: Normal behavior, UE cannot dial another party during a call.

Merge: Enable conference calling. Use on the originator of a 2-way voice call to dial a third party to invite them to join the call, to create a 3-way conference call. (This party will "own" the conference.)

Note: It is not possible to automate Emergency calls using the Dial activity.
