Help! My organization is trying to set up teleworker for a location that is outside of our internal regional network. Phones that are at other locations using teleworker and within our internal regional network work just fine. Phones that are not within it have no audio at all - the phones ring but neither end can hear the other, and when answered by a phone within the network it hangs it up. Mitel has looked at the tug logs and points back to us or a firewall issue. We have opened all the ports but something is still stopping traffic. Traces show that it is being blocked but we have been unable to make it work. This was supposed to be operational a month ago and no one has been able to resolve the issue: our vendor, Mitel or our corporate techs. Has anyone else ever had this? or have any suggestions - we are desperate enough to try anything. thank you!
