I am having classic "frame slip" symptoms on 4 different systems with 4 different providers (all full PRIs, Qwest, XO, Xspedius, and First Digital are the providers). By classic I mean pages cut short. I do not hear clicks on calls however, and faxing from a fax machine plugged into the asterisk box via an fxs port (no VoIP) faxes just fine through the PRI. Also, faxing directly from

Hello list. I've been running a Cisco VOIP WAN for the last two years using CallManager V3.2. The remote 1760 routers are set up as H323 gateways. I've got a VG200 that is my PSTN gateway with a full T1 voice trunk to the local CO. I'm also running Unity v3.x for voicemail. We are currently using two ATA186 devices that are using the G.711 codec to pass incoming calls on the T1

Check to see if you can get a IOS code leverl that supports SIP on the 6500. then maybe you can use your E1 card directly. you can also get a SIP version of the code for the 7960's etc Dave >>> jwi@weball.csis.dk 6/28/2003 2:56:12 PM >>> Hi Chris I've done a lot of things with Cisco AVVID solutions in the past. > CallManager).....am I right in saying that Cisco

OK I see the ponit (although I never said that second page is interrupted - I said that in some combinations of resolutions and TIFF options receiving fax "spits" another blank sheet of paper beside the clearly received first page). I have read someware (some faxing tutuorial) that there is some kind of control code (6 EOLs I belive) that should be in TIFFs between pages and that

Hi, I tried to use txfax to send several faxes at the same time. It seams, that one can't send more than 3 faxes at once, or one risks to get 50% and more aborted faxes due to errors. The CPU usage is below 97%. I tried with Opteron and IntelP4: same result. Ok, I know, that faxing via a digital line is complicate, and I shouldn't complain, but I would like to know, whether these are

Hi, People often send me audio logs from spandsp's soft-fax machine, where they have problems with corruption in the middle of a page for most or all of their faxes. Their problems are usually due to frame slips. However, recently I have received audio logs from two people who generally have great success with my software, but who find one or two machine regularly fail to send faxes

I've made some modifications to zttest in order to use it as a frame clock accuracy tester / slip detector. I'm not certain if that was it's original purpose, but it seems that a lot of folks try to use it that way. The result is something that I'm calling ztclock for now to help avoid confusion. I'm including the source at the end of this post. You can compile it by placing

I am trying to use spandsp 0.0.1k-whole. I have 2 X100P working well for inbound/outbound calls. I have tried libtiff 3.6.1 and 3.5.7 With 3.6.1 I get only faxes all black, and 3.5.7, I get blank vertical lines and the rest all black also. During the transmittion, apparently there is nothing that can indicate any error except some "Training errors". The sender fax thinks that the fax

Hello, I'm trying to receive faxes with asterisk. My configuration is like this: PSTN fax -> ISDN -> Cisco router with VoIP module -> Asterisk When I try to send a fax from PSTN fax I got the standard fax signal, Asterisk starts rxfax application and then call ends and there is no tif anywhere. On the fax display there is still one message: Calling... Part of my extensions.conf:

TDM04B whit 4 FX0 modules spandsp 2pre18 AMD XP box asterisk@home when i try to send a fax this fails on sender side in a middle of transmition, the receive side(* box) keep working 35 seconds on RxFax command after sender hang up, and no tif file has generated. in other post have a info about frame slips, but not how to resolve it. How i can solve this poblem? thanks David Romero

I have a potential client that wants to send many faxes simultaneously, over E1 trunks. How CPU intensive is spandsp's txfax? How many concurrent faxes could be sent by a decent CPU (e.g. Xeon 3GHz) before timing starts to get disrupted?

Thanks for the information Lee ! Still, something is still strange to me, since this two Panasonic Fax machines are receiving at least 20 multi-paged faxes a day (they are in same office as both Asterisk boxes, and me :) ). Beside that, POTS lines in those two faxes are from same PSTN switch as line in X100P in one of Asterisk boxes, and the ISDN PRI lines in other Asterisk box is from same PSTN

I've gone through about 5 computers and two linux distros (wbel and fc3) trying to get a system that doesn't show symptoms of frame slips, can receive faxes, and doesn't show CPU spikes with the tdm400p active. Unfortunately I haven't had much luck. I asked Digium whether there was a recommended hardware platform, and the best they could come up with was a Dell 600SC - but they

Hello! I?m trying to add fax functionality to my asterisk installation. Right now I?m focusing on receiving faxes. This is not explained in a book, but I assume that I can use same context, add ?fax? extension and if someone calls to send fax - it will autodetect. Right? Per book, I made following setup additions: 1. In sip.conf [general] I added: ;FAX stuff faxdetect=yes t38pt_udptl=yes 2.

I am testing Fax for Asterisk. But, I meet a problem. I try to Send a Fax (.tiff) from the first asterisk (Asterisk1) to the second asterisk (Asterisk2). Asterisk1 initiates an INVITE with audio G.711. Asterisk2 accepts this INVITE. Immediately, Asterisk2 sends an re-INVITE with T.38 to Asterisk1. But, Asterisk1 responds with "488 not acceptable here". I double check t38pt_udptl = yes in

I installed spandsp on our asterisk server to get faxes. It works however the images are a little off. Sometimes a few pages will be together, pages missing and sentence missing. Is this normal for this program? Any input would be great. Thank You Eric

Dear all I have a Asterisk server (version 1.0.7) running with a TE110P card on a 3Ghz P4 machine (running nothing else but asterisk) So far so good. Today I was trying to receive faxes using spandsp fax client. I used spandsp v0.0.2pre18 (which compiled against libtiff 3.5.7) It compiled fine, installed fine, run fine. But when sending a fax (from a Brother fax machine) the image received

I tested SpanDSP as an internal extension, and it worked like a charm. Now I am trying to receive faxes from a toll-free nufone DID. I am running g.711uLaw in on this line, so no to cause too many problems. However I receive the following errors after the fax is finished receiving: so the fax comes in Executing RxFAX("IAX2[NuFone@198.22.67.70:4569]/5",
