With the up-coming changes to broadband migrations and the abolishing of Migration Authorisation Codes (MACs), AAISP has launched a new "anti-slamming" service to allow customers to "lock" their line against unwanted migrations to another provider. This extra service, which is completely free, works on much the same principle as "domain locking" where domains can be locked against migration. The process is simple and allows each line to be locked against migrations for broadband or the underlying copper pair "phone line" part of the service. It is just a "standing order" from the customer to AAISP to reject all migrations. From the 20th, any migration request that then comes in is automatically rejected if anti-slamming is enabled. An email is sent to advise the customer of what happened, including a simple link to turn off the anti-slamming if they do wish to migrate after all. The anti-slamming service has been provided by popular demand after many customers expressed concerns that their lines could be "slammed" (maliciously taken over by other telcos) or that mistakes could lead to unwanted migrations, and it would be very easy to miss the notice of transfer that is sent before the migration goes ahead. OFCOM do not seem to have created any "fast correct" of mistakes, so an unwanted migration could mean waiting another 10 working days to fix the situation. Slamming is just one of the many concerns over the new migration process. There may still be ways LLU providers can take over lines, as can happen now without a MAC, but this new service should avoid mistakes and give customers peace of mind. The control pages for the line include a simple link to enable or disable the anti-slamming service.
