Grandstream VoIP Phones


Who else on the list is using them, particularly in a hosted environment? We've just decided to transition to them as our primary recommendation instead of the Cisco SPA series. We did it because of the value and feature set, like having an inexpensive phone with a small BLF, which a lot of customers asked for. I'm wondering if others have tips they've learned along the way, or any advice they want to offer. Also anyone using the advanced features like the browser for anything useful?

Fax Detect On Demand


Using Asterisk 1.8.mumble. We would like to use fax detect on demand.

Still Having CDR Problems.


Hi all,

I'm ironing out some remaining issues from a 1.6.x to 10.2.x upgrade.

I really need to use adaptive cdr's because I'm trying to store jitter statistics and such.

If I unload cdr_odbc and load, I no longer get new cdr's.

My cdr_odbc.conf contains: ================================================[global] dsn => diehlnet username => user password => password pre-connect => yes loguniqueid=yes dispositionstring=yes ================================================ The diehlnet dsn refers to an ODBC datasource, so here is my…
