High Availability with Samba and Heartbeat
Since I get so much from this list I thought I would share a project I've been working on and how it works with samba (3.0.1). It is Samba related so I hope it's not off topic. I've set up a HA solution with redundant Samba Domain Controllers throuth the "Heartbeat" package at: http://www.ultramonkey.org/download/heartbeat/1.1.3/redhat_9/ I have two "Redhat

switchtype QSIG and Asterisk implementation
Hi, Is Asterisk "fully QSIG-compliant"? I currently have an Alcatel 4400 connected to Asterisk 1.2 and 1.4. Zaptel versions are 1.2.26 and 1.4.11. I am using switchtype=euroisdn and all works fine. However, it seems that Alcatel's latest firmware has dropped support for euroisdn which is really despicable. So now I need to see if I can migrate to QSIG which is supported by

replace astdb with a cluster-capable sql database engine
I've been searching the Internet for information regarding the replacement of astdb with a modern sql engine. There are several reasons one would like to do this. First of all, external applications have a hard time reading/writing to the now-old astdb format. Also (and this is what interests me most), the sql astdb could easily be clustered throughout several servers (I'm looking for a

Ultrastmonkey? Ultramonkeyast? Astrimonkey? High Availability and Asterisk
Hi All, I've been labing up some HA Asterisk senario's using LVS, Ultamonkey, Asterisk DUNDi, OpenSER. UltraMonkey setup went pretty easy, workes fine with Debian Sarge, used the example on the ultramonkey website. LVS_NAT is a different story, a bit more complex and requires another server/director sitting in front of 2 asterisk servers. Also have in production OpenSER proxying calls

High Availability and Load Balancing
Hi All, I am currently researching on doing high availability and load balancing with a couple of Linux servers, most specifically doing service takeover on top of Heartbeat. The scenario is: - 2 DSL lines from a single provider - 1 Broadband line from another provider Internet / | \ | | | /

DAHDI/ZAP overlap dialing
Hi, I have a PRI euroisdn link between an Alcatel PBX and Asterisk. I'm having some trouble with overlap dialing. Suppose I dial '874053' from an Alcatel extension ('7034') where '87' is an Alcatel prefix of type "ARS Prof.Trg Grp Seiz.with overlap". I'm expecting Asterisk to receive '1004053' (where '100' is a prefix which always shows

replace astdb with a cluster-capable sql database engine (was: Re: asterisk-users Digest, Vol 44, Issue 22)
unix-odbc with Asterisk Realtime is one good way to use a different backend DB than MySQL. I haven't heard of "bit rot" problems running it over long times, but I'd like to if there are any. I'm particularly interested in seeing reports of Asterisk Realtime backed by Postgres. The problem with pointing dialplan DB functions like Set(DB) at unix-odbc (or any relational

CEEA:2005-1130-2 CentOS 4 x86_64 drbd / heartbeat - enhancement update (Extras Only)
CentOS Errata and Enhancement Advisory 2005:1130-2 CentOS 4 x86_86 drbd / heartbeat - Enhancement Update (Extras Only) We are pleased to add drbd (with integrated heartbeat) to the CentOS extras repository. DRBD is a block device which is designed to build high availability clusters. This is done by mirroring a whole block device via (a dedicated) network. You could see it as a network raid-1.

load balancing SIP extensions
What I would like to do is have two identical * servers which accept registrations of sip extensions 4000-4999. If I define a rrDNS or LinuxHA then I should have load-balanced registrations. However, say ext. 4001 is registered on *1 and 4002 is registered on *2, if 4001 tries to call 4002 then I would like to do something like: - lookup 4002 on *1, try to establish a call if it's

faxes received on mISDN
Hi, My initial setup for receiving faxes worked as follows: fax call arrives on ISDN BRI connected to a BOSCH PBX, signal sent to ALCATEL PBX via PRI QSIG then finally sent to ASTERISK via PRI EUROISDN. The Asterisk server then forwarded the call to a iaxmodem and HylaFax received the data. All worked fine. Now I got rid of both BOSCH and ALCATEL in the "fax path" and it's as

override/redefine asterisk DB function
Hi. Is it possible to override the standard DB function in Asterisk? My dialplan contains a lot of calls to "Set(DB(...))" and "${DB(...)} which of course use astdb to store/read data. I would like to stop using astdb and switch to Clustered MySQL (I don't suppose "clustered astdb" exists?). So instead of rewriting extensions.conf and replacing the DB calls with

Asterisk ZAP/DAHDI reads phantom digit on overlap PRI
Hi, I've noticed that a small but meaningful quota of calls from my Alcatel PBX to Asterisk are failing. This does not always happen and it is not easily reproducible but on high traffic I do get a large number of cases. Example: Alcatel PBX extension 7085 calls Asterisk PBX extension 6145 over a PRI E1 link. I see this in the Asterisk log: Dec 14 14:10:31 VERBOSE[11378] logger.c: --

AstDB/Berkely DB - Hash function? Balanced-Tree? b-Tree? Linked List?
Does anyone know enough about the implementation of AstDB to know whether the data structure is a Hash function, a Balanced-Tree, a b-Tree, or a Linked List? I'm trying to estimate the lookup 'cost' of a AstDB with around 160,000 keys? Obviously I already know that it WILL WORK, but the question is whether the data structure is optimal in the Berkeley DB AS IMPLEMENTED in Asterisk.

high availibilty (heartbeats) - a good way to ensure automatic redundency?
being from a telecoms background, the thought of a single asterisk box solution (even in a low production environment of say <10 phones) worries me slightly! starting from say a base of asterisk@home, you would have several MySQL databases, in addition to numerous config files. I have looked at high availiblity solutions, and from a hardware monitoring point of view, its relitivly straight

Asterisk DIAL() premature timeout on a PRI trunk to legacy PBX
An Asterisk extension calls an Alcatel extension via a PRI link which rings 4 times for about 10-15 seconds and then drops. So if the Alcatel user doesn't answer within 10-15 seconds the call is aborted. (A timeout is *not* specified in the Asterisk Dial command.) It seems however that either Asterisk or Alcatel drop the call prematurely (it's more likely to be on the Asterisk side). What

Where are phone registrations kept?
Hi, I've built an Asterisk HA cluster by means of heartbeat and drbd. The following folders are stored on shared storage and referred to by means of symbolic links: /etc/asterisk /var/lib/asterisk /usr/lib/asterisk /var/spool/asterisk /var/log/asterisk I was under the impression that phone registrations were stored in /var/lib/asterisk/astdb and as such preserved when failing over.

PRI QSIG Asterisk - Legacy PBX
I have a PRI E1 link between Asterisk 1.4.24 and Alcatel-Lucent OmniPCX Enterprise R9.0. As EuroISDN it works fine. However, I need to move to QSIG because of a firmware upgrade on the Alcatel PBX which doesn't support EuroISDN (please don't ask why). Besides, I've read somewhere that 2 B Channel Transfers "should" work with * 1.4, the latest 1.4 libpri and QSIG. So this
