Multiple E1 configuration question
Hi all- This question is for those familiar with EuroISDN setup. I have a customer in Europe where I'm going to install an asterisk based system with 4 E1's. The customer will configure them all in one large hunt group. My question is about the E1 channel configuration. I know that usually single E1 spans are set up with 30 channels (1-15 and 17-31) as the voice (bearer) channels and

CPU power required - Asterisk
Hi- I'm almost embarrassed to ask the following simple question, following John's excellent and rigorous bandwidth analysis (see earlier thread): I have a straightforward Asterisk application, IVR-only (no connections between channels). It will simply decode DTMF's and speak prompts (probably A-Law encoded) on a number of E1 circuits simultaneously. Realistically, how many

BRI and E1 in same system
Hi- Anyone using the Junghann's quad BRI card and the Digium E100P in the same system? I'm having a configuration problem where I can configure the cards one at a time (with the appropriate drivers loaded) in a system, but when I try them both together, neither will work. They both work fine one at a time. Probably has something to do with the channel numbering. I've tried

Fix for Redhat 9 zombie AGI processes
Hi all- Thanks to Mark Spencer for finding this patch: If you are experiencing leftover zombie processes from your AGI scripts that have terminated, this is apparently due to a RedHat 9 threading issue introduced in a recent update.... To get rid of this, try entering the following line before you start asterisk: export LD_ASSUME_KERNEL=2.4.1 It works for me - I'm still checking to

Question about cdr_sql fields
Hello- Is it possible to set the CDR record field called "accountcode" from within the dialplan? Or is there another way to cause this field to be set, preferably without using AGI code.

T100P-E100P circuit board differences
Hi- Perhaps someone with an E100P in hand can answer this: I just received an E100P from Digium (I normally buy quad boards) I noticed that the circuit board says "T100P" on it, and I assume that the T100P and E100P both use the same circuit board. Can someone please confirm that their E100P says "T100P" on the artwork? Thanks Scott Scott M. Stingel Emerging Voice

Good system board to use with TE410P?
Hi- I'm looking for an appropriate system board to power a system with two (2) Digium TE410P cards. Since these cards require the 3.3 volt PCI, I'm considering vendors like Tyan for the motherboard. Can anyone please tell me their experiences with the Tyan i7501 series (Xeon-basd), or recommend an alternate motherboard? Thanks Scott Scott M. Stingel Emerging Voice Technology Inc.

Experiences with Fedora 1
Hi all- Over the past week or two, I've been trying out asterisk under Fedora 1 Linux (RedHat). In my setup (single and dual Xeon motherboards), I have so far had a very good experience in terms of performance. In doing E1 load testing, I've found that Fedora handles heavy load much better than RedHat9, probably because of its better use of the multi-threading capabilities of the Xeon.

"Glare" condition - How well does asterisk handle?
Hi- I have an upcoming application that requires use of PRI channels that are primarily used for high-volume incoming traffic, but that are to be used for outbound calling as well. Of course, one option is to have dedicated outbound channels reserved, but this is an inefficient use of channel resources. Normally PBX's are designed to have the CPE yield to an incoming call if a particular

Tuning the Linux kernel?
Hi all- It's often mentioned here that recompiling the Linux kernel may improve the performance of asterisk. My question is: Does re-compiling the kernel have any effect if there are no changes to the configuration? What parameters will typically improve performance? Thanks for any insight! Scott Scott M.

Help: SMS in UK
Hi- Having a little trouble with the SMS application in the UK. I've read the wiki topic and also the BT documentation SIN 413, which describes the service technically. I've been able to successfully send messages from my customer's ISDN landline to various mobiles, but cannot get the mobiles to be able to send messages back to the landline. I've tried sending from both Cellnet

PRI integration with Marconi switch
Hello- Has anyone had experience connecting to a Marconi switch (in the UK) using E1-PRI connections (TE410P)? In a new installation, my customer is getting yellow alarms on every channel about every 30 seconds. These alarms clear themselves immediately and then re-occur in another 30 seconds, ad infinitum. I used the same configuration that I've used successfully in the past while talking

Malloc debug kills asterisk?
Hi- In trying to track down a possible memory leak in asterisk, I've discovered that the "show memory allocations" command crashes asterisk (causes it to stop handling calls, although it doesn't seg fault). The related "show memory summary" works however. Before I post this to the bugs list, can someone else please confirm this problem? You need to enable malloc

TE410P ERRORS under load
Hi all- HELP! This is actually a revisit of a problem that I had earlier with E400P's at a customer site. Customer still gets locked up channel problem, but has learned to live with it (channels clear themselves after several minutes). The symptoms, which I believe are directly related: I'm having problems with tons of framing and "read" errors on my E1 connections (and

Dell PowerEdge 750 rackmount
Hi- I have an upcoming order for a bunch of asterisk boxes, and I'm considering using an "assembled" package for the server, instead of building them from components as I usually do. Does anyone have experience with the Dell PowerEdge 750 server, or any other 1U rackmount server for use with asterisk? Thanks in advance Scott Stingel Scott M. Stingel President, Emerging Voice

H.323 Audio problem UPDATE
Update on this problem: I gave up on the "native" h.323 because, like others, I couldn't get audio working. (yes, I tried disabling FastStart in ast_h323.cpp - no change) So I went and got the OH323 code from www.inaccessnetworks.com. Glad to say that everything seems to work so far. Not only does audio work, but even the handshaking is now working in both OpenPhone and even

3.3v PCI board - TE410P photo
Hi- I have posted a photo of the TE410P Digium card on my site, so that those wishing to purchase a compatible motherboard can see physically what the PCI slot requirement is: http://www.evtmedia.com/TE410P.htm I believe the required slot is a 64-bit, 3.3 Volt PCI, most commonly found on Xeon-based motherboards. A 64-bit slot is longer than the TE410P board requires, but the PCI connector

Problem with AGI "Record File"
Hello- I've been writing a number of AGI scripts in Perl, and so far everything's working ok. However, yesterday I tried the AGI command "RECORD FILE" for the first time, and my channel locked up. Trying to stop asterisk produced a segmentation fault. There may be a bug here, but first let me make sure that I have the command line right (as the documentation is a bit sketchy)

OpenPhone <-> Asterisk w/H.323
Hello- In order to satisfy a customer requirement, I've just build H.323 under asterisk (using the specified versions of OpenH323 & PWLib, and trying to follow the instructions religiously), and it seems to have come up fine. When testing with with OpenPhone (Windows version 1.8.1) and NetMeeting, I've gotten some intermittent results however. All my calls are from a PC to asterisk -
