Main number rings Ldn key 199 and i need it to go to the auto attendant after 4 rings June 5, 2019 at 10:15 am #5301 Michael WiblishouserParticipant If I remember correctly you have to look at the abandoned call for the tenant. LDN keys are designed to ring until answered. You could always reach out the Mitel installing partner for advice.
