We have been looking into reports of an issue with outgoing calls to mobile numbers.
When our two of our Sales team are leaving a voicemail, once prompted to start recording a message on the mobile number being called, the voicemail system starts the prompt dialogue again to record a message.
Some of the recordings we have listened to the mobiles voicemail service either restarts itself between 30-50seconds after starting to leave a message and returns to going round the digital prompt to leave a message again, sometimes even going round the digital prompt twice in quick succession after restarting.
This happens on two of our extensions so far!!
We are running a 3cx phone system over a VPN with a external provider and use Yealink T46g phones.
If anyone could shed some light on what this issue might be, it would be most helpful
