Hi! Is there anyone that are using a E1-channelbank and have any tips about some type? Im looking at the TE410P and use one port for a PRI (Euro-ISDN, I think we're using some slightly modified version here in Sweden, but I'll check that tomorrow) and connect one port to a channelbank for 30 analogue telephones. It would also be great to ge...

We are a voip terminating company, we're using Channelbank with FXS modules, Rhino, CAC, etc.. What we're wondering is, is how to would you echo cancel a channelbank. Of course we're realizing that cancel'ing on the T1 (on Ast) does no good (we think?) because the analog conversion is at the channelbank. Suggestions? Lowering the gain helps but...

Hi All. I'm working on an * configuration. We require 8 inbound POTS lines, and CT1 or PRI seems like it will be quite expensive at that level. I've read that a T1 Channelbank plus the T100P would be a (the?) way to go for this situation. What is the recommended channelbank for use in this scenario? From searching the archives I see a lot of suggestions to get "a channelbank" from ebay. I would prefer to be able to use new products so I can easily duplic...

Ok, the Zhone sucks and the Adtran 750/850 seems to be a little too expensive. Can anyone recommend a decent channelbank that won't break the bank? TIA, -- Troy Settle Pulaski Networks http://www.psknet.com 540.994.4254 ~ 866.477.5638 Pulaski Chamber 2002 Small Business Of The Year

...d to connect Asterisk to a PRI and throw in a T1 Adtran channel bank into the mix for fax machines would the following work? Connect PRI line from telco to Port 1 on the Digium Wildcard TE205P. Connect Adtran TA-624-T1 to Post 2 on the Digium Wildcard TE205P also, would I need a crossover to the channelbank or is it a patch lead like the connection to the PRI any hints / tips greatfully received thanks to Steve Totaro for the nudge in the right direction!

...cards, and one TDM2451E card. Has anyone on this list done something similar? It would be great to hear some comments regarding a smilar setuyp/planning - Do you think is it better to distribute resources among multiple (more than two), lower-port-density asterisk servers? Or is it better to use a channelbank for that purpose? Cheers -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Does anyone know whether faxes work good when they're connectected to a channelbank ? regards, Leon

...efully 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 them and connect each with a T1. I don't really want to run 7 T1 + the 2 PRIs into one asterisk box for performance reasons. Ideally, several 48-Port SIP->FXS channelbank woulds be ideal I guess ;-). Does such thing exist? Or how do others do this? C...

...ium.com] On Behalf Of Matt Florell Sent: Wednesday, February 15, 2006 7:39 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Aasterisk large-scale deployment w/analog phones Hello, If you are doing that many analog extensions you might want to consider 4 channelbanks and a quad T1 card instead(or two 2-port cards in two servers). Four TDM24XX cards will draw a whole lot of power and would be much harder to replace than an exterior channelbank if something goes wrong with one of them. Cost should be about the same overall(depending on which channelbanks you buy...

I've got an * system that is having some real problems with 1.0.2. The biggest problem is that calls going through my T100P get choppy for about 10 seconds every 1 or 2 minutes. Asterisk is running on a debian stable system with current packages. The T100P is plugged into a Adit Channelbank with 8 POTS lines hooked up to the Channelbank. I've watched the vritual memory and CPU status on the * box during the call and the system is totally idle. Looking at the verbose logging in *, there isn't any obvious activity on the console that corresponds with the choppyness. It sounds...

Hello All, I'm looking to get some feedback on which solution of providing FXS is going to have the best results with faxing. I'm only looking to see what method is going to provide the best digitization into Asterisk, not for transmission from Asterisk to else where. Any recommendations of specific channel banks are welcome. I will need to provide approximatly 216 FXS Ports and need

...bably marketing is putting in their own equipment out there. I install a product that does exactly that. A paradyne jet fusion. It takes care of the part of which channels are data and which are voice. If it's anything like these, the lines will come out on pairs. You will then have to use channelbank and FXO/FXS cards to get it into your phone system. The jet Fusion FXO part is still in beta, so we have to drop off FXS. You can find tons of FXS channelbanks for cheap on Ebay. FXO's are much harder to come by, so try and get them to drop them off FXO so you can channelbank in FXS. Beside...

Hi all, We have been fighting with telco for a entire week. Today they came here with a LITE3000 to analyze what is going on. When I configure zaptel with no external clock, E1 gets aligned/synchronized with bit rate in 2048000 bps, both me and telco. span=4,0,0,ccs,hdb3,crc4 But when I configure span4 to get clock source from telco they become unsynchronized. TElco bit rate stays in

In our experience, the total cost of softphones(money, reduced sound quality and lower reliability) in a large call center environment is actually greater over time than the cost of a channelbank and cheap analog headphones. We've tried 2 softphones, 2 kinds of SIP VOIP hardphones, 2 kinds of SIP analog adapters and we've tried channelbanks over the last 3 years. Right now we are half done with our conversion at all of our in/outbound telemarketing rooms to channelbanks. The first 2...

...mer has several fax machines and analog phones (some of them have to be explosion-proof). around 50 analog ports in total are needed. as we are in E1 land (germany) we have 64kpbs per channel. most (affordable) channels banks are T1 (56kpbs per channel i assume). the questions are: - could the T1 channelbanks be connected to a TE405P with two channels in E1 mode (telco and hicom pbx) and two channels to the channel banks (i think yes, but just to be shure)? - will the faxmachines work (56kpbs-64kbps)? is asterisk translating this (btw. how do faxes work from europe to north america - the telcos hav...

Hi list! The stability of * with fax (or the lack of it) is causing me headaches. To solve it, I was thinking to put a TE205P card in the * box, connect the E1 pri on one port and a channelbank (I was thinking of the Rhino) on the other port in T1 mode. (Has anyone tried this??) The TE205P supports channel bridging which sounded like the ideal (but not cheap) solution when combined with a channel bank. When checking with Digium support if E1<->T1 bridging will work they replied...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been seeing some strange issues recently as it relates to our Asterisk phone system. Let me give a little background on things: We have a T1 provided by Knology. We recently had an outage of Internet and phones. The following problems (except for the log messages) seemed to have cropped up after the outage. I was prompted by a friend of mine

First question: Do you need to use a special phone to use SIP? My setup is X100P and TDM10B (I have 2 computers with the same setup), will I be able to use SIP? I already have the two computers calling each other using IAX, but I would like to see if I can get them to work using SIP. My current setup: On computer 192.168.10.50 **sip.conf*** [general] port=5060 bindaddr=0.0.0.0
