Narrative:
Aircraft landed in ZZZ, us, about XA35. At this time the captain wrote up the first officer's push-to-talk switch. Maintenance control was informed that the aircraft required a jack for a microphone for the first officer. Maintenance control told the maintenance worker to call back if the aircraft was not equipped with a jack. This person never called maintenance back and it was assumed that the aircraft was properly equipped by maintenance control and myself. It was found that there was no jack equipped in the aircraft at around XG00. The aircraft was promptly grounded until the aircraft was properly fixed. Between the time the MEL was written and the time the mistake was found, the aircraft was dispatched and flown for 2 revenue flts. From the point of view of myself and maintenance control, we should have followed up on the problem. If the worker did not call back, we should have called him to make sure the situation was correctly taken care of.
