If the call is no longer logged on your equipment there is not much you can do. Telcos only record outgoing call data.
Cable customer since 1993. Services: FH TV, Sky Sports & Movies (2xV+), Talk Unlim Telco, VIVID 100, Virgin PAYG Mobile
As nodrogd has mentioned, we record outgoing call information for billing purposes but not much on incoming calls that aren't recent so we wouldn't be able to trace the call for you unfortunately.
Sorry I couldn't help as much as I'd like.
