I have an elastix system that has been set up and working well for ~20 extensions, local and remote. Most phones are either Linksys SPA942s or Polycom 501s. One problem I haven't been able to overcome is that I cannot get the temporary conferences created by elastix to work. I have three permanent conferences set up via FreePBX that all work perfectly. However, when I go to the elastix web GUI => PBX => Conference and set up a temporary conference there, I cannot dial into it from internal extensions or externally via an IVR. When dialing the conference number from an internal extension, I get the error "your call cannot be completed as dialed". When dialing the conference number via an IVR, I hear the error "I'm sorry, that is not a valid extension." I noticed that the time zone appears to be hard coded to PST/PDT, so I've made sure to account for the time difference, and I've even set the conference to start hours before the current time and to stay active for 24 hours to ensure that is not the issue. I've also found that I can go into the conference participants page and invite extensions, which will ring them and allow them to join. Can anyone help me understand why I can't dial in to these conferences?
