Very much depends on the exact situation, my opponents stats, the table flow, existing bubble factors, the other stack sizes and so on. Very hard to give you an exact answer without a given situation. Yours is a bit too vague. Antes are important as well.
In the end it is quite easy:
Give your opponent a range. If he is a regular and there is no important bubble factor (and the antes are standard Stars-format) the range should be like this (75%):
22+,A2s+,K2s+,Q2s+,J2s+,T2s+,92s+,83s+,73s+,63s+,52s+,43s,A2o+,K2o+,Q2o+,J5o+,T6o+,96o+,86o+,75o+,65o,54o
Now you can do the math. Which hands are good enough to call? You need ~41,8% equity for a break even call (chip EV):
22+, Ax, Kx, Qx, J2s+, J6o+, T5s+, T7o+, 98o, 96s+, 86s+, 76s
Each of these hands has at least 42% equity against your opponents range. Therefore you should call with these hands if the range for your opponent ist accurate.
