similar to: TDMoE - best signalling method?

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

Anybody have any issues running tdmoe on kernel 2.6+? I've got Suse 9.1 + 9.2 running 2.6.5 and 2.6.8 respectively, and when I enable dynamic spans between them, both boxes dump something similar to: Badness in local_bh_enable at kernel/softirq.c:141 [<c0120768>] local_bh_enable+0x48/0x60 [<c02952b0>] dev_queue_xmit+0x230/0x240 [<c02a0980>] eth_header+0x0/0x140

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

I'm scoping out HA for a relatively simple Office/Call Center PBX. Current setup uses a TE412P with 4 PRI our telco with SIP hard/soft phones for users. Some outbound also goes to a SIP provider. Active/Active looks to be too much hassle for an installation this size, so we're looking at adding an extra * in an active/passive configuration with Linux-HA in between them. Does anyone

When I was trying to run mutiple E1s over TDMoE, the zaptel would drivers complain about too little memory, whenever I added more than 31 channels. Requesting 62 channels in a dynamic span gave me ... span creation failed: Cannot allocate memory upon loading the zaptel drivers. How would you go about running, 8 or 16 say, E1s over TDMoE? Would you create multiple dynamic spans or just one large

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

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

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

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

Hi, Is there any mailing list specifically for zaptel-users ? If yes, then, sorry to bother you people, i could not locate it. Can anybody post a link to it ? If not, then i hope, this is the right place to ask zaptel related questions. I'm using vanilla zaptel 1.4.3 on custom Linux 2.6.15.1. I've have a Redfone FoneBridge2 (TDMoE) gateway which i want to use with the zap drivers. It

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 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

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

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

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

Hi, I have just begun working with TDMoE running between 2 fiber nics the dynamic span works great. In my main asterisk box's startup file I just 'modprobe tor2', then start asterisk. The zaptel, ztdynamic & ztd-eth modules all load by themselves when tor2 is loaded. If I stop asterisk then 'modprobe -r tor2' the tor2 module is removed but the other three remain. If I

Juan, I dont see people here with "attitude" or any need to shut down this list as you suggested. Contrary to your experience, I find people to be quite helpful here. Steven's comment "Start here and then ask a real question" is definitely not arrogant IMHO. He is just trying to knock some etiquette on Luan. Besides, he did give him all the answer Luan was looking for.

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
