I setup my Freshphone account on a Huawei B315 router connected with Afrihost Rain LTE and an analogue phone. Once it was setup I miss called my cellphone and it worked. When i tried calling the 087 number it also worked.
Later when I actually needed to make a call the sound on the phone is constant as if it is not registering that I am pushing the buttons. I can still receive calls but cannot make any calls.
I have double checked the settings and everything seems correct.
Changed the handset and it worked.
