I have an interesting issue here.
I have a tenant I support that has a Sangoma IP phone.
When the tenant presses the voicemail button, it accesses the voicemail and I hear the prompt but…
Whatever button I press to access whatever option the voicemail prompt is asking to press to access different options, it does nothing at all.
What happens is then the voicemail prompt will cycle through a second time and no matter what button I press on the keypad, the call hangs up.
I have tried different Sangoma phones but the issue still persists. I even tried resetting a Sangoma phone with the same issue.
Any help is greatly appreciated.
