Total Amount Of Asterisk Installations


Counting any Open Source package is difficult for many reasons. There is probably not a reliable answer to this question since there are at least 4 major “flavors” of Asterisk out there (1.4, 1.6, 1.8, 1.10) and open and commercial source. It is reliably > 10,000 and quite possibly over 100,000 or even over 1 million. The Asterisk folks might be willing to tell you how many downloads have been done from , but that wouldn’t tell you the real number. Maybe a good start point for an estimate would start at 200,000+ if you are including all of the versions and types. But then we might still think…

Tell external number instead of internal number


Hello, I have an internal extension, e.g. 1005 which is being called from an
external/public number like 123456789. Now when it comes to the spoken
voicemail information it says something like "number 1000 not available",
however it should say "number 123456789 not available". How can I configure
this? I already googled and I guess this is really easy, but I just
couldn't figure out how to do this ): So thanks for any hint :-)

911 multple-alert question


Can you set up asterisk so when a 911 call is placed, in addition to the
call out to the PSAP, it also alerts multiple other phones on the switch
and will display detailed information. Such as alerting a receptionist
or security guard there is a 911 call elsewhere in the building and the
location of that call within the building? If so, how? Thanks in advance for the help...

Administering phones


I'm new to asterisk, currently working through Asterisk, The Definitive Guide. I have a couple Grandstream 200 phones and a Polycom 501 to play with. The Grandstreams were very easy to configure, but the more capable Polycom almost drove me crazy. There is so much conflicting information on the web about necessary config files and names of those files. Anyway, all my phones are now working on a basic level, but it occurs to me that once spend a lot of time learning Asterisk, I might then have to spend an equal amount of time figuring out how to configure…

SER Still recommended for large installs?


I'm reading some information that recommends using SER / OpenSER for
large installation to offload SIP traffic from the Asterisk server. However, it looks like the information might be dated. I'm looking at a potential 750 SIP phone and 150 Analog installation,
all internal network, PRI trunks, and am trying to nail down an
architecture. Opinions? You think I skip the SER box if I'm using 1.8? Thanks!
