Unable to call through Salesforce

[fahim]

Hi

I have integrated salesforce with 3CX PBX system successfully. I cannot make calls to Leads and Contacts mobile number it gives me an error message which is //Outbound call could not be processed: Destination is empty//

but I can make calls to leads and contacts phone number

Can I know what was the problem?

Thanks

Have you installed the Call assistant software which will install the 3cx tapi driver on the PC?

Yes I have installed Call Asistance Software. That's why I can make calls to lead's and contact's phone in salesforce. but I cannot make calls to mobile phones of Lead's and Contact's in Salesforce.

Please help me to solve this problem
