I have this issue too - searching the various phone threads it seems that different phones have this issue - the connection is O2 - for me it is 15 minutes and the call drops. Many report its 15.32 exactly when the call drops - no solution found yet :-(

15 mins exactly if I looks at the call history...
Look at status.o2.co.uk its says for my local postcode...
