Good afternoon,

I installed Asterisk on a server and want to know if there is any way to set it up so you can use the same input line as one of the outputs.

Thanks in advance

A greeting

Can you clarify what you mean by “input line”? Are you referring to a phone line, VoIP trunk, or something else?

Hello,

I want to put one mobile phone line. I was reading and I know that I can put the same line for input and output with type=friend, but I don’t know if it is possible with GSM network.

Sorry for my english, I’m spanish girl and I not speak english very well, if you don`t understand anything you can say to me.

Thanks

For a GSM device I would only expect 1 simultaneous call per SIM card.

Thanks,

The objective of this is to can decrease the call volume of this number. Other possibility is one phone with 2 sims.

I’ m not very sure now. I`m evaluating all the possibilities because is the first time that I’m using Asterisk

Thank you very much again

type=friend doesn’t really do that, and, in most cases type=peer is better even when you use the line in different directions at different times, or have multiple simultaneous calls on it.
