I have a North American BRI configured as National ISDN (NI-1) on an SBC (Nortel?) switch. SBC calls this "FastTrak ISDN", and it's surprisingly inexpensive -- less than two POTS lines. I've been trying to find an inexpensive PCI interface solution to connect this to Asterisk as voice lines. I prefer ISDN BRI over POTS lines because of the improved signalling, fast dialing,

...so in sip.conf). I think that's a problem of the ISDN line (used with I4L modem drivers), that does'nt pass the DTMF to the end point of the call. Is there some thing i can do on the conf files or I have to search the answer into the source tree? I googlized a bit and found some patch to isdn_tty (that should solve the problem of receiving dtmf from isdn line when calling with a person), but unfortunately, the kernel version is different and also correcting a bit the patch, it doesn't work for me - i still get errors with patch. Nothing found for the contrary use: sending dtmf over the...

...mingly working with 4 snom 200 phones. I cannot dial in or out using a DIVA isdn card When I dial out i get "not found xxxxxxx" on the handset. When I dial in i see in /var/log/message isdn_net: Incoming call without OAD, assuming '0' isdn_net: call from 0 -> 0 1856 ignored isdn_tty: Incoming call without OAD, assuming '0' isdn_tty: call from 0 -> 1856 ignored I have tried "isdnctrl eaz MSNNumber" but am still seeing these messages. Am I missing something fundamental here? Here is my modem.conf context=remote driver=i4l language=en type=autodetect...

...nalogs phones and all is working very well between two zap stations. I have tried different Passive isdn card ( no hfc so I can't use zaphfc driver) Anybody have an idea to fix this problem ? BTW, I have compiled my kernel with the dtmf patch for isdn_tty.c so.... The cpu usage is 25% during a conversation, 75% idle I have a PCI latency of 32 msec With or without APIC, no changes.... It seems that the voice is buffered and sended too slowly to the i4l channel and so a delay is present afetr a short time...

...h fancy features, and the voice mode used to work fine with my old passive HFC-PCI. Anyway this is not a big problem as all voicemail will be transfered to asterisk. Just curious about this failure? The serious problem is that asterisk no longer answers calls: they are seen by isdn_net and isdn_tty but even if ignored are not passed to asterisk for further processing. Is there a way to have i4l attach only to one controller on the 4BRI? - if I load the capidrv module, at first it seems to work: Apr 25 08:08:19 zenon kernel: capidrv-1: now up (2 B channels) Apr 25 08:08:19 zenon kerne...

...card using i4l. Outbound dtmf doesn't work (and never has), but there has been an annoying problem with false dtmf detection in calls (that could be triggered easily by blowing into the receiver on the remote end). I looked through the list and found two patches that need to be applied - 1 to isdn_tty.c in the kernel, and another to chan_modem_i4l.c in Asterisk. This morning (and I say morning - because it's now 4:50am Friday here) I was feeling adventurous, so I applied the patches and recompiled my kernel. Once that was done, I started up Asterisk and noticed that there was no false DTMF...

One of my buddies signed up with GV yesterday with a view to using them on his * server. Problem is that the settings they gave him don't work with asterisk. They do however work with X-Lite. Any ideas? He's using the settings outlined on my web page. Mark -- Mark, G7LTT/KC2ENI Randolph, NJ http://www.g7ltt.com

...t stops working (it neither dials out nor accepts incoming calls). Trying to dial out just logs: -- Executing Dial("IAX2/steve@steve/1", "Modem/g1/48:19") in new stack and then sits there. If a call comes in, the kernel logs: isdn_net: call from 19 -> 0 41 ignored isdn_tty: call from 19, -> RING on ttyI0 But Asterisk doesn't log anything at all. Anything not going through the ISDN keeps working just fine. I _think_ this is only happening after an outgoing call hangs up (the incoming calls seem to be fine). Also, on an outgoing call, if the phone on the PS...

...xcept that I can not see the called number/MSN of incoming calls within Asterisk and because of this I can not route incoming calls directly to the correct extension (DID). The number is received via D-Channel from the telco by isdn4linux (I can see it in /var/log/messages (generated by isdnlog,isdn_tty,isdn_net)), but I can not see it on Asterisk-console (even with verbose/debug enabled). For testing purposes I included the first two lines in extension.conf: --- part of extension.conf------------snip------------- exten => _234.,1,Dial(SIP/zok1,1) ; "234" is local number without ext...

I'm looking to use Asterisk with Verizon ISDN centex service in the US. I'd be connecting to an NT1 so I'd need an S/T interface. Users would have SIP phones registered with Asterisk and sharing the ISDN lines. The only PCI ISDN card that will support ISDN signalling in the US seems to be the Eicon Diva Server cards. These are hard to find and very expensive ($2500 for the Quad
