1. A method performed in a call processor of processing a telephone call, the method comprising: receiving via a first interface a telephone call, the telephone call comprising voice signals and data signals;generating an identifier for the telephone call; andwhile the call is in progress: receiving first information signals encoded in the data signals via a first interface and second information signals via a second interface;associating the identifier with the first and second information signals;generating a request based on the first and second information signals;transmitting via a data interface the request to an external entity;receiving via the data interface a message from the entity to identify success or failure of the request;matching the received message to the telephone call in dependence on the identifier; andprocessing the first and second information signals in dependence on the success or failure of the request. 2. The method according to claim 1, the method further comprising: transmitting via the second interface at least some of the voice signals and the data signals with at least some of the data signals modified to prevent all of the transaction information signals being transmitted via the second interface. 3. The method according to claim 2, further comprising modifying at least some of the data signals by masking or replacing them with other signals. 4. The method according to claim 3, wherein the data signals comprise audible tones. 5. The method according to claim 4, wherein the audible tones include dual-tone multi-frequency (DTMF) tones. 6. The method according to claim 2, further comprising transmitting at least some of the voice signals via the second interface at the same time as receiving at least some of the data signals via the first interface. 7. The method according to claim 6, further comprising transmitting via the first interface voice signals received via the second interface at the same time as receiving at least some of the data signals via the first interface. 8. The method according to claim 1, further comprising receiving data signals as part of the telephone call, the data signals being operable to navigate a menu system. 9. The method according to claim 1, further comprising blocking the first transaction information signals received via the first interface from being transmitted via the second interface. 10. The method according to claim 1, wherein the telephone call comprises a transaction or the collection of sensitive information. 11. The method according to claim 10, wherein the sensitive information comprises at least one of: personal information, financial information, or associated information to enable identification of the user. 12. The method according to claim 11, wherein the personal information comprises at least one of: address data including a postal code or a zip code, a date of birth, a national insurance number, or social security number. 13. The method according to claim 11, wherein the financial information comprises at least one of: a credit card number, a charge card number, a bank account numbers, or a sort code. 14. The method according to claim 11, wherein the associated information includes at least one of: a password, or an answer to a security question. 15.
