similar to: TDMoE vs IAX2

Hi all, I'm having some problems getting TDMoE setup for the 1st time. I have a TE405P installed in the main server with an ethernet cross-connection to the secondary machine. (Yes, I know about IAX2 but I want to use TDMoE to simulate using T1s.) I'm using -HEAD from yesterday. On the main machine /etc/zaptel.conf: loadzone = us defaultzone=us

Robert, > Is there a product to simulate a PRI trunk? (Robert > Goodyear) TDMoE emulates a T1. ;) Once the TDMoE link is up, Asterisk just sees 24-lines that appear to be a T1 instead of having to deal with all of the complexities of VoIP. This is useful, since probably 75% of the utility of VoIP is really just the fact that it can run over a network. It's also handy because it

I have a T400P in my main building M and am going to put asterisk boxes in two buildings A & B. I already have our wan on fiber running between the buildings (including some extra strands) and the distance is beyond straight Ti distance so I would need csu... to use copper. It occurred to me that I could use TDMoE - and it may be less costly. My assumption is that the best to avoid the

Hello, We've just started using TDMoE(local T1s connecting between Asterisk servers in the same building over the LAN) to connect a few of our high-availability servers instead of using crossover T1 cables. The 3 servers we have connected to each other over TDMoE are running just fine and we have no audio quality issues or bandwidth issues, but I'm considering using TDMoE to connect 8

Has anyone succesfully used TDMoE on Fedora Core 2.6.12+ Kernel versions? I'm having the issue that is in the Mantis bug database with badness with the kernel. My Story: I can get the dynamic span to come up and show OK in the zttool on both machines. However i get errors every second (Warning: detected alarm on channel 1... then channel 2...) And then the next second, i get : alarm

I'm just experimenting with dynamic spans using TDMoE, which looks ideal for clustering Asterisk boxes with low latency (i.e. 1ms for TDMoE compared with 20ms for IAX). When using normal E1s and T1s, I've always used ISDN signalling: either EuroISDN or NI2. So naturally I tried that over the TDMoE. I've found that I get a lot of HDLC errors and the D-channel is up and down like a

Hello, I want to link several * boxes together. Some of them are dedicated as "user" servers (SIP and IAX clients connect to them) and some are used as PRI servers (where the PRIs are hooked onto). I think TDMoE is the only channel type where you can group different Interfaces into a single group. E.g. for using Dial(ZAP/g1/12345), I think you cannot group different IAX accounts

If I have a system with 1 machine to handle incoming H.323 calls and then multiple machines to distribute them to T1 ports over TDMoE, where does the codec translation take place? Does it take place in the master system or does it take place in each of the slave TDMoE systems? Also, any idea how many concurrent G.729 calls a system like this would handle?

Before I put myself to the task (next month, maybe) of surveying the CPU costs of transcoding, perhaps someone else has already done this work and would be willing to share it or refer me to a link of previously published data. My reviews of the mailing list with various keywords were unsuccessful in finding adequate references, though I admit I only spent 20 minutes looking. What I seek is

I was trying to establish a TDMoE span of 4 channels between two Asterisk servers. Machine A has a T100P to our PBX. Machine B has no Zaptel hardware. With 4 channels (e&m signalling) the red alarm never clears, and eventually machine A panics. With 24 channels, the TDMoE span seems to work perfectly. Is this hardcoded somewhere? I don't really need a full 1.544 Mbps between my two

Hi All, Please bear my ignorance but what is TDMoE used for? Illustrations with practical applications, scenarios or set ups will be most appreciated. Thanks Luan

I was trying to use TDMoE and I lasted with two problems. First of all I can't configure the dynamic span to use CAS signalling but documentation (by Mark) says that you can use any type of signalling (and this includes CAS I guess). My second problem is related that my Linux system crashes frequently due to ztdynamic and friends. I'm using a 2.4.26 version kernel and zaptel

We have been pretty much able to solve our echo problems, except for the primary mode in which we desire to operate our system. See system diagram at bottom. Prior to making adjustments to cancel echos (all echocancel=no): Call Type Result (Before) --------- --------------- CP <- LEC PRI * TDMoE * FXO -> AP

Hello, I've been using TDMoE accross 2 * boxes for months. It was working well, but * would crash when anyone would try to connect via h.323. So, I got the latest CVS release and compiled without h.323 support. After I made and installed the latest CVS the TDMoE channels stopped working. They have been working great (especially after we got echo cancel working them, thanks Mark) and the

Dear All, I bought one IP PHONE from Integrated Networks which was showed to wiki too: http://www.voip-info.org/tiki-index.php?page=Intergrated-Networks I have problems with the Asterisk authentication. It does't want to LOG IN to Asterisk; it always says "LOG ON FAILED". I'm using the IAX2 protocol and all paramters seems to be correct. Does somebody use the same IP PHONE with

Hi, I have two asterisk machines, chomper and otao. otao is otao.ieworks.net, has a public IP address (66.101.11.61), but no PSTN connections. chomper is at my house, behind NAT, but has a single X100P PSTN connection. I would like to establish two way calling between otao and chomper. Right now, I can call my extension on otao (2101) from my x-lite softphone on chomper, but I cannot call

In all the information on Asterisk it takes about TDMoE to link asterisk servers together. Is this IAX??? How would I use TDMoE. Maybe my first question should be, What is it??? -------------- next part -------------- An HTML attachment was scrubbed...

I've been experimenting with the zaptel TDMoE stuff and I've got it all working. Calls go from one asterisk box to the other, with no issues, except they don't bring the callerID along with them. I tried the e&m signalling from the wiki and I thought maybe that had something to do with it, so I just changed it to half fxsks and fxoks and that didn't help me any, I still
