Compare two date fields only if one of the date fields is NOT blank.

Trying to write a formula that compares two date fields only if one of the date fields is NOT blank.

Here is what I have so far.
IF(
Last_Sales_Call__c  >  Last_Telephone_Sales_Call__c,"Yes","No")

Basically I need the formula to compare Last Sales Call vs Last Telephone Sales Call only if the Last Telephone Sales Call is NOT blank.

IF( NOT( ISBLANK(Last_Telephone_Sales_Call__c)), IF( Last_Sales_Call__c > Last_Telephone_Sales_Call__c,"Yes","No"), "No" )

The formula shows "No" if the Last_Telephone_Sales_Call__c is blank.
