Hi everyone,

I got DSU II system with Comdial impact LCD phone. When someone call in and system pick it up, after a greeting, ask caller to press ext#, then the call transferred to that ext#. However, the caller cannot hear ring sound when system transfer to ext. In fact, that ext# phone do ring from outside, but caller not. Please help to figure out what is going on.
Thanks.

Have your Telephone system tech set the voicemail transfer type for that extension to Blind Transfer.

Hi , I think on the DSU even if you do blind transfer the outside caller will not hear ring they will hear whatever you have on hold. The FXII/DXP are different but if my memory is right DSUII will just do hold music.

If you set the transfer in Voicemail to blind tranfer the caller will hear the keyset ring when release by voicemail. We assume that the voicemail is a KEY VOICE model.

Jim, you made me check it here. Yes, you do get ringback tone from the DX80, I have it set to blind transfer and you get about 3 seconds of MOH then ringback tone until it is answered or VM picks up. Also making the same assumptions as FTorres.

You get ringback on DX80 and the late revs of DSUII but earlier did not. Had to have MOH to compensate for silence during transfer. DSUI did not.

oops. This is a DSU11 not a DX80, oh well.... RBF got it covered.

Hi,

Thanks for you all. I really do not know the status before I got this system. How do I change the setting to hear ring sound? Thanks.

You don't. That will require technician level programming. Contact your vendor. It would be to complicated to talk you through it on this forum. Someone with a thorouh understanding of the telephone and voicemail system database will be required.

Try just hooking up a music source to the music input on the side of the cabinet. Then at least they should be hearing something, rather than just silence. That could maybe at least get you by until you can have a qualified technician look at it, as suggested.
