Phone app problem

[supersang12345]

Hello everyone,
I have an iphone 3gs ios 6.1.3 jailbroken.
A few days back the phone app failed to make outgoing calls but I can receive calls, texts, and even use gprs.
What could have been the problem and how to make it work??
I even checked other sites but they told it could be a problem with the auto update of date and time option or the show caller id option......
but this did not help me
kindly give me a solution for this problem please
thank you

Try this :
1- rest settings (from the settings app)
2- turn off the phone then turn it on
3- if you think that a cydia tweak case the problem, enter save mode , go to cydia , delete the last tweak you installed

Sorry for my English
I hope you understand

I tried it but I dont think its about cydia
I guess its something to do in settings.......
I turned off auto update of date and time and turned on show my caller id
its worked occasionally if i did that
anyways i restored it an its working fine..........
I still do not konw what caused it
