I have done this successfully with a PRI installation, but was wondering if it is possible with analog lines. My customer would like calls on two separate numbers to be answered with two different greetings. However, after navigating the DAT for each line and being routed to two different Virtual extensions (251 or 252), on an RNA condition they would like the calls to be forwarded to one mailbox. So whether the call goes to extension 251 or 252, they want the call to go to mailbox for 251. Setting Forward and Transfer settings to 3999@251 does not work for extension 252 as it does with a PRI.
