solution to congestion can be as simple as adding a "1" to the number dialed (missing 1 can often cause the call to be rejected). however, it can also be caused by not having money on the account and by trying to dial a country you are not registered for (calling UK from the US when the carrier has you marked for US calls only ... congestion!). it can also result from calling a disconnected number.

the simplest solution is to call your carrier and ask "why did you reject this phone call?". Then fix whatever they tell you was broken.
