Common/Reasonable Assumption on DID/Channel over-subscription

Report
Question

Hello All, just throwing this out there. What are people generally using these days
when designing their services, esp. those that require a user to call a DID
to access their system, similar to calling card services. There was a time
when this used to be 50 to 1 for DIDs, and about 10 to 1 for number of
channels bought in SMB with IP-PBX. I believe this would have changed today and assuming a service is pretty
popular, the ALOCs are longer due to cheaper rates and convenience of
calling. Does anyone have…

Card on the server,

should go to the caller not the pilot number For example PRI Numbers Range -> 31303000 - 31303099
Pilot Number -> 31303000 So if i need to set caller number as 31303008 for example and not as

ITSP failover for PRI

Report
Question

Hi, I still have the same problem trying to configure ITSP failover in
extensions.conf for a connected PRI. Any comments thoughts or direction
would be greatly appreciated. I sympathize with wanting inbound DID failover. If we have a client with
multiple DIDs we will spread them across two or three ITSPs so that all
inbound connectivity will not be lost if one of them has an issue. I have a little experience with using SS7 from when we set up multiple call
centers in Norway for Telenor. Using SS7 we were able to determine incoming

I am more than happy to purchase new DIDs from a different provider if they will consistently work and…

Hi, Does anyone know a source for multi-channel Hong Kong DIDs (probably 10 channels to start with) that can receive international calls? We are being told that multi-channel DIDs can only receive calls from within Hong Kong. Thanks Dan Journo

two questions regarding incoming call

Report
Question

Hello,
I want to make an agi script to match incoming DIDs with usernames. I tried to do such entry in incoming trunk. [DID_diddw]
include = from-didww [from-didww]
exten = 3130XXXXXXX,1,AGI("did.php")
exten = 3130XXXXXXX,n,DIAL(SIP/${yup_no},20)
but when i run the rule it says
chan_sip.c:20152 handle_request_invite: Call from '81.85.224.41' to extension
'31301111111' rejected because extension not found in context 'from-didww'
Cant I use such agi scripts on incoming calls? PS:
exten = 3130XXXXXXX,n,DIAL(SIP/1111) works alone.
My second question.
I got two incoming trunk sip channels on my server. One…

Base memory usage

Question


Asterisk gurus.... I just installed asterisk 1.8.1.1 along with FreePBX on a fairly small
VPS (512mb standard, 512mb "burst"). I note that the asterisk process
is using about 209mb of memory just doing nothing (not configured to do
anything yet) In contrast to this, my 1.6.1.2 installation from a little over a year
ago uses only 40mb and it's fully configured and running with about 4
months of uptime (2 trunks, 4 channels, 3 DIDs, and 4 extensions.) Any ideas on how I can get the memory consumption down on my new
