Here is what I have discovered:
In order for an extension’s Personal OGM to activate correctly with DISA AA directed calls, the DISA Ring Time before intercept Timer (508) needs to be greater than the Call Forwarding Start Time (202). To activate the Common OGM if an extension does not have a Personal Message, set the DISA IRNA to BV (438-440) for the desired COs to BV (01-24) as required for each time service mode.
Increasing the Call Forwarding Start Time (202) allows for more time for the extension to be answered. Setting it to 20s provides about 4 rings before the transfer takes place.
If anyone has any further insight, please let me know.
