crm contacts lead to Cisco SPA-303 freeze when accessing 3cx phonebook

[AlexKor]

We recently enabled salesforce integration. Everything worked fine until crm contacts started populating our 3cx phone book. Then our voip phones(cisco spa-303) started to freeze every time user tired to access 3cx phone book. Removing all CRM contacts fixed the problem, but until the first crm contact appeared again.
So ideally i would like to stop contact population, because we don`t need that, but I cannot find the option to disable that.

Hi @AlexKor

As you see from our limitations list on this model, they work with a limited size only and they are supported as a legacy device.

To avoid populating them you might have to manually edit your templates which is not something we support, but it may help in your case.
