Hello,<br>
<br>
I have an Asterisk server and a multiplexer connected via E1 boards
(TE133 Digium for the server and Lomif for the multiplexer). I have
connected a phone to the FXS board of the multiplexer and I am
trying to make a call to it. Through dahdi_tool I can see the rx and
tx CAS bits and when I change them I see it.<br>
Both rx CAS and tx CAS are in state 'idle', but when I try to make a
call I see the following error in the CLI;<br>
<br>

<br>
Would you please tell me what can help me to solve the problem. Is
there a problem with the signalling bits, configured in the
multiplexer or the configuration in the Asterisk.<br>
<br>
Thanks in advance,<br>
