Combine these SQL queries
<p>I have these two queries:</p>

<pre><code>--query 1
SELECT Account.*, Opportunity.* FROM Opportunity
LEFT JOIN Account
ON Opportunity.AccountId = Account.AccountId
WHERE YEAR(Opportunity.CreatedOn) = 2016

--query 2
SELECT outbound_number, count(outbound_number) as c
FROM [Telecoms].[dbo].[cdr]
WHERE YEAR(calldate) = 2016 and calltype = 'outgoing' AND Disposition = 'ANSWERED'
GROUP BY outbound_number
</code></pre>

<p>I'm trying to combine them so for each row in the first one I can also see the count from the second <code>WHERE Account.Telephone1 = outbound_number</code>.</p>

<p>What is the right syntax to get this working?</p>
