Hi, I'm testing an E1 with E&M signaling. Some of the problems I'm running into are the following: 1) if I try to configure any channel above channel 15, I start getting a "multiframe alignment error" on my telco test equipment. So I have my zaptel file only configured for 15 channels, like this span=1,1,0,cas,hdb3 e&m=1-15 2) When the test equipment tries to send me a DTMF string, I only get the first one. Any thoughts? Best, PauloHM

I think probably not. I had to fix some things to get proper access to the CAS signaling bits when I implemented MFC/R2. That makes me strongly suspect that nobody else has tried any form of CAS signaling with the E1 drivers. If you are using recent CVS code, the CAS bits certainly work for all time slots (they only worked for the first 15 before), but that doesn't mean that E&M will work. Note that E&M on E1s is implemented differently for just about every Telco that offers it. Regards, Steve
Also try to see the debug on the console (edit /etc/asterisk/logger.conf and put console => .....,debug) and restart asterisk in the console (-c) Then you should see what telco sends us. It might be that they use some diffrent standard than *ANI*DNIS* and sometimes instead of * they use #. regards Martin On Wed, 3 Sep 2003, Paulo Mannheimer wrote:> Hi, > > I'm testing an E1 with E&M signaling.
