Lamentably, for the present, I do not believe that we buy a T1 card for
Asterisk. As I said in another message of this thread, when trying to
communicate with an extension of the Siemens PBX, I obtain
"busy/congested".

When searching on the Internet if Asterisk requires some special
configuration to interact with this type of PBX, I found that some
Siemens models use proprietary protocols [1], although I'm not sure if
the problem I'm having is because of it. Our PBX has two parts. I have
understood that the smallest box (than it is on the other) is the DISA.
If it serves as something, in the later part it has model 7655.

Thanks for the explanation and clarification of nomenclature. And in
what cases it would be correct to use the RJ designation?

Thanks for your reply.
