We make net extension on device, and if I login on one PC, when I login on other PC, it is fault as follow:
I test it in experiment, the configuration is right, the dialing is successful. I can use one account to login on different computers, but if one computer dials to net extension, anther dials to net extension, it will be fault. Then I create a new user, and login on different computers, dials to net extension, there is no problem.
Suggestions and summary:
There is no data about if we could use one account to dial net extension, so please be careful when configurating.
