We are currently running Asterisk 220.127.116.11.1 (CentOS yum Repo Asterisk Web-gui SVN 2.4 revision 18.104.22.168) with SPA942’s v. 5.1.15(a). All of the sudden we lost the functionality of putting a user on hold as well as transfer calls during an outbound call. (Outbound meaning, I call your cell phone from inside our network, and put you on hold.) You can push the hold button on the phone and it will not do anything at all. Nothing found in CLI and nothing found in Debug as well. We flashed the phones to the newest version as well as tried 5 other versions with no success. We then moved the phones to a working network, and it did work. The problem Lies within the Asterisk phone system. All config files look the same, and nothing has been changed. Does anyone have any idea on why this would occur? Has it happened to anyone? Are we losing our minds? Is it a conspiricy? Haha. Anyone please help as it is always greatly appreciated. Take care, and enjoy your day!
