I have 15 extensions at a branch office connected by T1 back to the main office. Both are Legend R7.0 with Mmail 3.0 at the main office. Roughly half of the extensions ring to Vmail after the normal 5 rings, the other half take 10 rings before they transfer. all the extensions are in the same cover group. So I'm not sure where else to look to make all the extensions transfer in 5 rings. Thanks for assitance.
