I recently installed a Cisco SPA112 and registered a extension with no problems. The only problem is with Call Transfers. It is not possible to put the call on hold with, in this case, the R button (Siemens Gigaset). The same issue occurs when using a other type of Analog Phone. Also holding the # doesn’t work. You can hear a “click” when you try to put a call on hold (the one who is putted to hold).
I’ve searched the internet but could not find a solution to this.
If any logs are needed just tell me which one and ill provide.
Provider -> Elastix -> SIP -> SPA112 -> Gigaset C590 (Analog)
Cisco SPA122 Version 1.4.1
Hope you can help me with this.
btw: im not a expert in this
