See http://openbsc.osmocom.org/trac/wiki/isdnsync for a tool to calibrate (with appropriate HW).
If you don't have the equipement ... huh, good luck. You can always try random values until it works. If you have a USRP you can try to lock onto it and compare offset ...
Its possible to set the clock calibration to a fixed value, this was a feature introduced a while ago. The original clock calibration setting workes pretty good, at least from my experience. So if the clock is off due to using the E1 clock as a reference, it should be enough to set the orginal clock calibration value and switch the PLL to standalone mode.
