[Asterisk-Users] ADSI slow?

[Alfred R. Nurnberger]

ADSI is a slow inband protocol.
You will notice that when pressing a key in voicemail that the system
responds immediately but updating to a new screen takes a couple of seconds.
This delay is caused by the downloading of new screen data from *. ADSI is
based on the Bellcore caller id specs. So all downloading happens with a
modem speed of 1200 bit/s. This is a very slow inband signalling system
unlike Ciscos SIP phones where all the screen information is sent via a 10
or 100 Mbit/s ethernet connection.

Your second problem is most likely caused by the passwords set in your
phones.
Check the archives there were a few posts how to change the passwords in
your .adsi files.
If you bought cheap phones of ebay you might be out of luck though - if they
are provider locked then there is no way to program them without knowing the
provider specific password (according to Sayson)

I currently received two of the sayson 390 & 480 phones.  I like the style
of the phones, but was wanting some feedback from other users.
My phones seem incredibly slow whenever connecting to voicemail.  I've added
the security settings to my adsi.conf file & re-downloaded the script to the
phone.  It tells me it has a conflict with Slot1, so I'm unable to get the
graphical menu - BUT, I'm able to see the caller information on each
voicemail.

I've used almost nothing but Cisco 7940/7960 phones with asterisk and they
are very quick & responsive to the voicemail, where these Sayson phones take
app. 2 seconds to respond to key presses.

What has your experience been if you have used one of these Sayson 390 or
480 phones?
Thanks!!
