We had this two-minute standard, and as I said, you can choose between how many people you let in and how long people wait. We experimented earlier this year with letting more people through but then the people who were there had to wait a bit longer. We tried it out and we thought it actually worked reasonably well. We got some positive responses, so we're continuing with that. We'll have a little bit longer lead time but that would allow more people to get in. As a result, we're seeing fewer busy signals than before. That's not to say that it's perfect, but we tried that out.
We will continue with that. We're trying to take action now in advance of the new technology, which we will have next year. However, we can't just wait until next year and not try to make progress. We are trying to make progress at the moment, and then when the new technology arrives, we won't have to do so much manual routing of where the calls go. We'll have much more flexibility in the system to help us manage the calls and tell people their wait time will be x minutes and that they can choose to wait or to call back.
