I haven't started configuring the telecomunications part yet, but I bought a few microphones for two mds I have. I plan on first testing the intercom functionality and then connecting it to a VoIP provider. But, when I connected the microphones and tried to call another md, I get a message saying "Calling... Please wait" and nothing ever happens.
Any suggestions on what I should look at to begin troubleshooting this? I understand that there were some issues with asterisk, but I did the apt-get update and it seemed to install new versions of simplephone and stuff. The intercom functionality should work out of the box, right?
