Yealink Forums

Hi all,

We have installed a Yealink T49G phone on a clients Alcatel OmniPCX as a third party SIP extension. Outgoing calls are over ISDN lines.

The problem we are having is that the phone displays "Network Unstable" on the screen quite regularly. Is anyone able to shed some light on what this means and if there is a setting to turn this notification off?

Many Thanks,
Chris

Hi Chris,

If the network is not stable, the phone will show "Network unstable".
The phone will check the network status by itself.
Only the T49G has this feature, it's normally.
