Hi,

Does anybody know why the button redial doesn't work at 4620ip telephone?
The version is 2.0.18 And something else,can u tell me what settings are u using for the ip telephones?
for example at the ext. list for ip user, i choosed 20 packets and 729 simple and i still have problems with
voice. Some times they can't hear the others for the other site.

Thanks,

Costas...
