Hi,

I don’t know how to call this functionality, but what I want to do is join an already established communication between PSTN—FXS_connected_phone using my SIP phone (I have an asterisk v11 with digium TDM400P at home)

Is it possible? What I don’t want is using the conference sound and menu…. It’s just a normal call between to channels that I have to join for few minutes.

Regards

  • I had this set up once upon a time. It took quite a bit of dialplan hackery, but the basic idea is to create a conference bridge, use ChannelRedirect() to connect both existing channels to the bridge, and then join it yourself.

    This worked for a bit, but the last time I tried it, Asterisk segfaulted. Oops.

  • exten => 1234,1,ChanSpy(SIP/cisco1,qn)
    Assuming cisco1 is a sip extension.

    I haven’t tried it but below should work. exten => 1234,1,ChanSpy(DAHDI/1,qn)

  • In the telephony world that is known as “barge-in” and is a programmable option granting that right to specific extension(s) in systems that normally have automatic privacy. Not all electronic key and hybrid systems have automatic privacy, though most do.
