Good day,

I’m trying to set up a video conferencing solution for our office. Currently, my testing setup has my laptop running MicroSIP and a Debian VM with Asterisk installed on it, with the other end being a Cisco Telepresence SX20 box. Video calls from MicroSIP to SX20 work perfectly, but if I try to place a call from the SX20, it pops up a “Connecting” screen for a second, then the call ends with “Call has disconnected”. I’ve set Asterisk’s verbosity to 5, but the CLI reports nothing during the attempt. A Google search found a thread with a similar issue (however, theirs was with Cisco Unified Connection Manager), where changing the URI to include the domain helped, but on mine, the URI has gone from “1000” to “1000@xx.xx.xx.xx” to “sip:1000@xx.xx.xx.xx” with no change in behavior.

If anyone has experience with a setup like mine, I would very much appreciate any and all advice you can give me.

Best regards, Norman
