Earlier, for Click2Call, the “CustomerNumber" parameter was mail-merged in the Click2Call URL. Because of this, users were able to initiate Click2Call from both the Phone Number field and the Alternative Phone Number field.
However, the “CustomerNumber" parameter has now been deprecated.
Problem Statement:
The Lead’s Phone field was mail-merged in the Click2Call URL. Due to this, the customer was unable to perform Click2Call using the Alternative Phone Number field, and it resulted in an Invalid Number error.
Solution:
The alternative parameters that can be used instead of “CustomerNumber" are:
@leadPhone– Lead phone number without country code@PhoneNumberWithCountryCode– Lead phone number with country code
Using the above parameters will resolve the issue and allow Click2Call to work as expected.
