Human Factors
Called for push at X1; got the cleared to push and thought ramp said go to metering.  Contacted metering and received taxi instructions.  Received a call from the chief pilot making me aware that ramp wanted us to call them for taxi before contacting metering.Long day after a 3 hour sit and I believe that I just miss heard what was said on the push back. I have had only a handful of flights since being off and I should have questioned the Ramp Controller.I should have questioned the contact metering part that I thought that I heard and called Ramp again for taxi regardless.
I was on the intercom with the push crew while the first officer was communicating with Ramp on VHF2 to request push clearance. After pushback and disconnect I received a salute. With the engine start and checklist complete; I called flaps 1 taxi. The first officer contacted Ground metering who then told us to monitor Ground. I taxied about 100 feet up  the ramp but short of the taxiway. Ground Control cleared us to taxi to XXL. The first officer failed to call ramp control prior to contacting metering and I didn't catch it since I was monitoring VHF1. The first officer was fresh off of a 3 month leave of absence which could have contributed. Also; we just had a 3 hour sit in the airport between flights.  11+ hour duty day. Better frequency monitoring when using multiple radios.
Air carrier flight crew reported a deviation from the ramp taxi procedure and cited lack of flying as a contributing factor.
