How to link mobile SIM telephone number to telephone intercom as CO line or outside call number.

You can get Huawei and Tenda

@@Tech_Inside_Out Thankyou

You are welcome

Hello Jonathan, Am glad to hear from you. Greetings to you from Ghana.

Yes, your sim number will show to the one you are calling

By system programming, you can configure which extension or phone rings when an outside line call comes through but the system also has a default ringing extension for Outside line calls and i have intentionally connected the black phone to the default ringing extension port, that's why it rings. You can program it so that the white can ring as well.

@@Tech_Inside_Out thanks for the reply

You should use a router that has a Voice Service port, i know tenda and Huawei have such routers. You can get other brands but the important thing to check out for us the Voice service port

No.

Who is this please?

The video below shows how you can make and receive calls outside the pbx network ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Uqb_2yvRJZM.html

You can get it on Aliexpress or any IT item shop near you.

I will address programming later

Most welcome

Thank you.
