Does anyone know if this is possible? I get no rings or hold music during blind transfers from both of my gateways (grandstream 4108 and linksys single line (3102?) So you get silence until the user picks up, or until voice mail picks up. I found i get the same results blind transferring from any of my phones which are all linksys and cisco. Not sure if this is how it is supposed to work or if i have an issue. I do get hold music during a regular transfer. If i hit my auto attendant line i get hold music there as well after entering the extension.
