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

Hello all, recently i stumbled upon the I-TDM standard, e.g. see here http://www.picmg.org/v2internal/news2005.htm "SFP.1, also known as I-TDM (Internal TDM), is a companion protocol specification to SFP.0 that is optimized for TDM traffic over high-speed fabrics such as 1 and 10 Gigabit Ethernet (PICMG 3.1), Advanced Switching (PICMG 3.4), Infiniband (PICMG 3.2), etc. SFP.1 and SFP.0

Can anyone help me find a specification for the 23B + D Asterisk TDMoE (packetized PRI) link? I am having occasional packets arrive from the Asterisk Server that do not have the standard four leading characters in front of the MAC addresses, and am not sure what this implies. For now, I discard such packets. Also, I'm getting HDLC abort messages from the Server that occur almost

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

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?

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

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

Hi, I spent some hours working my way through the WIKI and a number of other documentations, but after all, three questions are still left: 1. I'm using a Fritz!Card with the i4l driver - no problem at all, my Grandstream BT 100 rings when I diall a regular phone number. Is there any need for me to configure the zapata.conf for the ISDN card to get a special asterisk feature or is this

Hi, We have a case where we need of 16 x FXS, 12 x FXO and 1 x E1. To do this using Digium products I need of 8 PCI slots. This is not possible to be done in one computer and that's why I try to start using TDMoE. Unfortunately all my tries are without success. The network is crashed everytime. Can you give me some ideas/suggestions how to solve this case? Best Regards,

I am planning to configure * box A with PSTN interface to route faxes to * box B (running spandsp) over TDMoE. I am using 2xGb bonded NIC's for connection between servers. Was wondering - does anybody have experience with TDMoE over bonded interface - ie. does it work ok?. - does anybody have feedback using this scenario for fax? another question, perhaps someone knows what's the

Hi all, Information on this topic seems a little scarce, so I thought I'd try the list.... Apart from the the coolness factor can anyone explain to me in what situation one would use TDMoE rather than IAX for communication betwwen 2 Asterisk servers?

I just came across http://www.voip-info.org/tiki-index.php? page=Asterisk%20TDMoE and seemed very interesting. It prompted me to question whether it would be more efficient to do TDMoE or IAX2. The application is very simple. I have two asterisk boxes. One is strictly a gateway to the PSTN using multiple T1s. The second is where all my extensions and dialplan are defined (the workhorse for

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

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

I have configured TDMoE sucessfully and I am able to make a Zap connection from one box to the other. The question I have is.. I'm getting repeated errors every second on both systems.. Oct 3 09:53:16 WARNING[4409]: chan_zap.c:6252 handle_init_event: Detected alarm on channel 1: No Alarm Oct 3 09:53:16 WARNING[4409]: chan_zap.c:6252 handle_init_event: Detected alarm on channel 2: No 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

Has anyone every attempted to set up a mini PC to achieve much the same functionality as the fonebridge box? The sort of thing I'm imagining is a micro itx board & case in a completely solid state configuration (flash disk, maybe a psu fan but only if really required), with a TE210P (or equiv) card(s). The sole purpose of this would be to be a bridge between E1 lines and TDMoE. The

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
