Parent fields values are not accessible from Trigger.new, you need to retrieve them from SOQL. Check the trigger below:

trigger Contactcallout on Contact (after update) {
    
    Map<Id, String> m = new Map<Id, String>();

    for (Contact c : [SELECT Id, Email, FirstName, LastName, Phone, Title__c, Account.Name 
        FROM Account Where Id IN: Trigger.new]) {
        if(c.RecordTypeId == '012D0000000BaFA'){
            Contact old = Trigger.oldMap.get(c.Id);   
            if (c.Email != old.Email || c.FirstName != old.FirstName ||
                c.LastName != old.LastName || c.Phone != old.Phone ||
                c.Title__c != old.Title__c || c.Account.Name != old.Account.Name) {
                WebServiceCallout.sendNotification(c.Id, c.Email, 
                    c.FirstName, c.LastName, c.Phone, c.Title__c, c.Account.Name);

            }
        }
    }
}

Try above code, and one more thing you should never hardcode a record id in apex.

(Edit: For some reason it doesn't allow me to post the trigger as Code, So added it as a HTML to the comment.)
