I converted to Version 10 a few weeks ago and tested the Skype gateway ( Ver 2.0.9919.0) so I'm pretty sure that this isn't a version issue. I've noticed that outbound Skype calls were not going through, I don't make that many of them, so it doesn't crop up that often. The 3CX log shows.. 11:09:32.812 [CM503020]: Normal call termination. Reason: Not available 11:09:32.812 [CM503016]: Call(3): Attempt to reach <sip:firstname.lastname@example.org.XXX.200:5060> failed.

The Skype trunk shows as registered in 3CX. However...when i opened the 3CX Skype Gateway, under Skype status, it shows Offline-Pending Authorization. Which is not the same status in the actual Skype program, I am On-line. So, it looks like a difference of opinion as to whether I'm On-line or not. Could a Skype update have rendered the Gateway inoperative? The PC has been re-booted and in fact this is happening on two identical machines,( one is a backup and only one is running at a time). When Verison 10 was installed I did not touch the Skype gateway and I'm pretty sure that i made a test call to the Skype Echo test to make sure it worked. I know that Skype had some hic-ups in the last while but I'm pretty sure that is all behind them , for the time being. Has anyone else seen this sort of issue? My next step was to remove then re-install the gateway, but i really don't want to do that it i don't have to.
