Hello Everyone, Having a bit of an issue which someone may be able to assist me with.... We have a call queue set up, and each of the SPA504 phones has a login and logout shortcut on the phone which is set up through the BLF settings in 3cx. Often we have found that an agent will press this button, hear a voice which tells them they are logged in, however their status has not changed and they are still logged out of the queue. As these are outdated phones, I have given all the agents their logins for 3cx and tell them to press the Q button there, which worked for a while. Now, however, I am finding that the agents are logging in through the website, it is showing the blue Q, but they are still not logged into the queue. The queue manager shows that they are not logged in. Why would their extension register this and the 3cx website, but not actually work? Any ideas? Thanks in advance.
