3CX V.8 -- Atom 330, Server 2003, 1 gig RAM, 80 gig HD. 12 users -- all are grandstream GXP 2020. 2x SN 4114 gateways to PSTN (analog). License = 16. Can anyone tell me why a transfer would be slow (i.e. 60 second delay before transfer is initiated) or why a transfer would just disconnect after attempt? These are blind transfers using both inside and outside lines. This is very disturbing. This entire system is less than a week old.
