Outgoing and incoming calls don't work with my EHS6T modem | Thales IoT Developer Community

December 13, 2016 - 2:59pm, 1852 views

Hi all,

When I tried to make an outgoing voice call with my EHS6T modem using AT command, I received a NO CARRIER answer. The connection is never established. I receive the same answer (NO CARRIER) when I try to allow an incoming call.

Could you please tell me what can be the root causes of this kind of behaviour? Do I have to change the configuration of my modem first before testing the calls ?

Here is a copy of the exchanges between the modem and the host:

command : ATD06******00;

Response : OK

Response : NO CARRIER

Response : +CREG: 1,"4F93","0025007B",2

Response : +CREG: 1,"4F93","002500AA",2

command : ATA

Response : NO CARRIER

command :ATI1

Response :

Cinterion

 EHS6

REVISION 03.001

A-REVISION 00.000.31

Thank you in advance.

Best regards,
