Prueba de la siguiente manera:

Código MySQL:

SELECT calldate ,src ,  count(accountcode) as todas,(SELECT count(accountcode) FROM cdr WHERE accountcode= 'entel' HERE src = '77000'
AND calldate BETWEEN '20110301' AND '20110401') as "entel"
FROM cdr 
WHERE src = '77000'
AND calldate BETWEEN '20110301' AND '20110401'
GROUP BY src DESC
