we recently upgraded to v8 of the 3cx phone system and love it. Thank you 3CX! All users are external and we use the 3cx Assistant and v 4.0.9878 softphone...all connected via Tunnel. Phone system running on win server 2003 box. Today we just had a really weird thing happen...in the 3cx mgmt console, under the "Phones" node, i noticed 1 extension had 60+ registrations and the list continued to grow by 1 about every 20 seconds. All other users only had 1 registration. When i looked at the Extension Status node in the console the bad extension continued to turn red and then green. It was like the software phone/assistant was confused and kept trying to re-register with the PBX. I had the user with the bad extension reboot their machine and that helped the re-registration problem (the list stopped growing), but all the other duplicate registrations were still listed under the Phones node. I then restarted the Phone system services and that didn't remove them. I actually had to reboot the box running the phone system. All extensions are working fine now (no duplicates). Has anyone else run into this? Is there anyway I can lock down the server so only 1 softphone/assistant can register at a time? Any feedback would be much appreciated.
