My system is DIDprovider ---SER---Cisco AS5350---Calling card platform.

Since December the 1st we noticed a large increase in the amount of wrong numbers received at the CC platform.

As this problem arrises once the call is established and there is no RTP relay I don't think is a SER question but I resort to your major knowledge to see if someone can enlight me about where to look to solve the problem. BTW. No changes were made in the equipment at neither end.
