.. _l5_troubleshooting_call_waiting:

Call Waiting
------------

**Problem**:
During an active phone call, the phone receives a second incoming call.
Incoming and outgoing audio for the active call cuts out, or the active call drops.

**Reason**:
Call waiting is not currently supported.
See :ref:`l5_cellular_networks_issues_call_waiting` for more details.

**Resolution**:
Call waiting must be disabled through your mobile carrier.
Contact your carrier (or `contact Purism Wireless Support <docs_contact_purism_>`_ if using `Librem AweSIM <Librem_AweSIM_>`_) and ask that the call waiting service be disabled for your line.


Incoming calls do not appear in call history
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

**Problem**:
Incoming calls that arrive during an active call are not listed in call history.

**Reason**:
Call waiting is not currently supported.
See :ref:`l5_cellular_networks_issues_call_waiting` for more details.

No mobile data
--------------

**Problem**:
No cellular data is available.
I see an orange exclamation point next to the cellular signal icon in the top-left of the screen.

**Reason**:
Mobile data is disabled.

**Resolution**:
Follow :ref:`these instructions <l5_add_cellular_access_point>` to enable mobile data.


.. _l5_troubleshooting_no_mic_input:

No outgoing audio
-----------------

**Problem**:
Others cannot hear me when I speak during a phone call.

**Diagnostics**:

#. Is the microphone :ref:`enabled <l5_kill_switch_terminology>` with the :ref:`hardware killswitch <l5_kill_switch>`?
    #. **YES**:
       Continue to the next step.
    #. **NO**:
       Power on the microphone with the killswitch, then re-test outgoing audio.
       Continue to the next step if the problem persists.
#. End the call and call the recipient at the same number. Does the problem persist?
    #. **YES**:
       Continue to the next step.
    #. **NO**:
       Problem solved.
#. Coordinate with the recipient (over SMS, etc) to turn up the volume on their phone. Does the problem persist?
    #. **YES**:
       `Contact Purism Support <docs_contact_purism_>`_ to discuss next steps.
    #. **NO**:
       Problem solved.


.. _l5_troubleshooting_no_incoming_audio:

No incoming audio
-----------------

**Problem**:
I cannot hear the other person speaking during an active phone call.

**Diagnostics**:

#. Place or receive a phone call to another phone for testing purposes.
   Verify that the person on the other line is speaking at a reasonable volume and near the microphone on their device.
#. Turn up the volume using the **Volume +** rocker switch. Can you now hear the other person while they are speaking?
    #. **YES**:
       Problem solved.

#. Place or receive another phone call for testing purposes.
   Verify that the person on the other line is speaking at a reasonable volume and near the microphone on their device.
