Translate "On call"

Question

I need to translate "on call", as in "if you have a problem after hours contact the on-call agent", where the "on call" agent varies depending on which agent is "on call", or available in case needed.

Answer 1

de guardia if it is for assistance, such as medical. otherwise, perhaps: contacte al centro de llamadas?

As annie says "estar de guardia" or "estar disponible" would equate "to be on call".
