Hi list, I recently purchased an ISDNguard from Junghanns. It came with no software and there is no sign on their website or in any of their documentation where to download it. I have looked in http://www.junghanns.net/downloads/ and there is no sign of it there either. The only thing remotly close ther is isdnguard-asterisk-1.2.13.patch. T...

Hi all, I recently purchased a Junghanns ISDNguard and to my horror I found out: - Junghanns technical support is non-existant - I can't use it without recompiling Asterisk with res_watchdog My situation: - Recompiling Asterisk with thrid party code is not an option us - We only need it for manual failover - don't require all the fancy mon...

Hi, 1. How have you connected your ISDNGuard (see http://www.junghanns.net/en/ISDNguard_produkt.html) box to your server ? Datasheet mentions RS232 requirement so I'm wondering if a USB-serial cord could fulfill this requirement ? 2. How does it go back into standard mode from failover mode ? Regards -------------- next part -----------...

...Background information: A client wishes to replace their current PBX with a new VoIP system. Currently they have 2 PRIs. I intent to set up 2 asterisk PBXs with Debian GNU/Linux on raided drives. These drives will be mounted only read-only to recover gracefully from power-cycles. I am considering 2 ISDNGuards in front of the machines. More to the point: The client has 160 existing analogue telephones which they don't really want to change right now, because a) they are very cheap b) the users don't need to re-train. I have thought of Rhino Channelbanks, but then realised I need to use 7 of the...

First, Something seems to be wrong with the list. I'm not the only person who has expressed seeing their messages either arrive late, or not at all. With that out of the way.. Is anyone aware of any type of failover device for PRI on asterisk? I've found the ISDNGuard, however it is currently not made in the U.S., nor does it run on U.S. power. Is anyone aware of a device that will detect (heartbeat?) if Asterisk is running, and if not, failover to a backup server?

Hi, I'm wondering what the best option to obtain a high availability asterisk server is. I currently use a TE410P (4 x E1) card. I'm thinking of 2 different solutions: - 2 servers configured with Heartbeat + DRBD (drbd mainly for voicemail....) and the E1 span plugged to the 2 servers (with a TE410P in each server). - 2 servers configures with Heartbeat + DRBD with the E1 span hooked

Hi list, Last Friday, an Asterisk server became unresponsive after ~8,5 months of smooth operation (~320000 calls). Server did reply to pings, but no ssh, no more console login. Also Asterisk no longer took calls, but ISDNguard watchdog was still alive. Looking at the logs after reboot, I could not find anything significant, except in a file created by the following command via a cron job: date >> /var/log/asterisk/calls.log ; asterisk -rx "show channels concise" >> /var/log/asterisk/calls.log...

For high-availability Asterisk when using PRI Lines, you might also want to check out our product (FSV-4PFS). It's available at www.failsafevoip.com Bill Also to add to the last post does this device have hardware echo cancelation? if it does it could be a great replacement, if not may not be what I'd really want to use. Thanks, tom I've been looking at the RedFone foneBRIDGE2

...on connecting our Asterisk to our legacy PBX (an Avaya INDeX). I was originally going to sit it between our ISDN connection and the INDeX (tried it, worked ok) but now I intend to hang it off a spare PRI card just so should the * fail we keep our ISDN's at the INDeX, yes I've looked at ISDNguard but little info from the manufacturers. Anyhow, I'm now thinking about using QSIG, I've configured two spans of a TE405P as switchtype = qsig and connected them back to back for testing and calls are ok. However, I cant find any documentation relating to what messages I might see come...

Hi All Does anyone have any ideas around what processing power is needed when bridging PRI channels and recording? I am not sure how the bridging takes place with and without recording? I basically have a situation like this: Telko <----> Asterisk <-----> Legacy PBX Where the lines are PRI's between Telko and Asterisk and Asterisk and the Legacy PBX. At what level does

Hi, I tried "upgrading" from debian's 1.4.21.2 package to vanilla 1.4.22 but then my TE410P alarms stay RED and no zap channels can be created, even if they are correctly listed by "zap show channels". I tried adding "dahdichanname = no" to asterisk.conf's [options] to no effect. Going back to 1.4.21.2 brings my alarms back to OK. This is with zaptel
