asterisk users - Dec 2009 - How to use SIP hints and BLF for realtime extensions on Aastra phones?

Hi,

I need to make use of BLF feature on Aastra 6757i phones but its an Asterisk
1.4 using realtime architecture. Extensions are defined in realtime database
and dial plan is in AEL. I am able to correctly setup hints in the dialplan,
but they don't work. Did some research and found out that hints don't
work
work with realtime extensions. Is there any work around?

On voip-info I read that Snom phones can use BLF without using hints. Is it
possible to do similar on Aastra phones?

Any guidance will be highly appreciated.

You need to enable rtcachefriends=yes in sip.conf

I am having echo issues on our Asterisk box using a PRI circuit.  I was using
the software echo cancellation and that helped a bit but didn't solve it
completely.  So I went and bought a Digium echo cancellation module for the
TE121 card.  That made it even worst, getting more echo on external calls and
between internal extension to extension.  The echo doesn't happen all the
time, but enough to get complaints from our users.

Completely fed up with the issue, I removed the module from the card.  Can
someone guide me on how to fix/tune/address the echo issues.

Thank you!
