TopStop Limit for Green Talk

The TopStop limit is a protective feature for Green Talk. Once the limit is reached, outgoing calls may be restricted or blocked.

A typical indication is that incoming calls continue to work, but outgoing calls are no longer possible.

The TopStop limit protects against unexpectedly high telephone costs. Costs may be incurred if an unauthorised person gains access to your VoIP credentials or if a connection unexpectedly remains active. To prevent high costs, a limit of CHF 50.00 per month is set by default for each greenTalk phone number.

If the call costs exceed CHF 50.00 within one month, chargeable outgoing calls are blocked.

In this case, you will hear a busy signal when dialling a chargeable phone number.

Incoming calls remain possible.

Outgoing calls to emergency numbers remain possible even when the TopStop limit has been reached:

Open the settings for your telephony product.

Automatic Reset of the Limit

The call costs are automatically reset to CHF 0.00 at the beginning of the following month.

If the TopStop limit was reached and not increased, outgoing calls will be possible again from the first day of the following month.
