Place Call

Place a voice call from a real SIM and measure connection and call quality.

Place a voice call from the SIM: to another SIM in the platform for an end-to-end voice test, or to any number. Measure the time to connect, hold the call for a chosen duration, optionally play an audio file and record the call for quality scoring.

Parameters

ParameterRequiredDescription
Access technologyNoNetwork technology, including VoLTE profiles. Default: automatic.
Call Receiver NumberYesThe number to call. Supports variables.
Max wait timeNoHow long to wait for the call to connect. Default: 30.
Call durationNoHow long to hold the call once connected. Default: 10.
Play file during callNoPlay a reference audio file into the call (used for MOS scoring on the receiving side).
Record callNoRecord the call audio. Default: off.
Compute Audio MOSNoScore the recorded audio against a reference file. Requires recording.
Call should failNoInvert the verdict, for barred numbers.

Results and metrics

In the action report (result):

FieldDescription
wait_connect_duration_in_secondsTime for the call to connect.
post_dial_delay_in_secondsDelay between dialing and ringing.
call_duration_in_secondsTime the call stayed up.
total_duration_in_secondsEnd-to-end action duration.
ceer_responseThe network's call end report, for diagnosing drops.
access_technology_reportThe technology used for the call.

In Analytics, each run feeds the call measurement with cellular_call_duration_seconds, cellular_call_connect_duration_seconds, cellular_call_post_dial_delay_seconds, and duration_seconds, tagged by status, antenna, and access technology.
