Hello everyone and support team. I need to add * at the end of each calling number. I installed GSM-gateway + 3CX Systev v12 + 3CX Phone for Windows When I typing +79995552233 and push Dial button, I want it sending like a +79995552233* (with the * at the end of the number) Thx. ps: I found only how to add prefix, but it's not what I need. pss: I think this might be at VOIP/PSTN gateways section > Outbound > To (and here I need to modify a Custom Field) or may be I need download the SIP client which may to add POSTfix at the end of the dialing number.
