similar to: T38 fax pass thru to Cisco as53xx

Hello, I've got an ISDN PRI circuit terminating in a Cisco AS5350, which in turn is talking to an Asterisk server via SIP for call origination and termination. Seems simple enough, and it works for the most part, but: 1) Caller ID name data comes in on the PRI, but doesn't appear to get handed off to the Asterisk server via SIP, at least not in any format that Asterisk

Hi My call flow is T38 static IP gateway --> Asterisk --> Sip Provider--> PSTN Call is placed in reverse direction - from PSTN to T38 Gateway. T38 GW reinvites with T38, and asterisk passes it along to the SIP provider. The SIP provider challenges it and asterisk reponds to the Challenge with INVITE with Auth credentials...however, the Asterisk changes the SDP and replaces the T38

Dear all, I'm trying to enable Asterisk to work with FAX using T38. I've tried Asterisk 1.2.4 with the available patch found at URL http://bugs.digium.com/view.php?id=5090 and also with the new 1.4 Beta3 that is announced to support it too. With both Asterisk versions, I've sent with success FAXes between two FAX machines each one attached to an ATA interface, both registered in

Hi, I am looking for an Mail-2-Fax and in a second step Fax-2-Mail-solution that works via T38 with Asterisk, currently still version 1.4 but it also should work with 1.6. For Mail-2-Fax I am thinking that you either have to install a special printer-driver on your Windows-PC (Mac and Linux would be good too), where you can print your fax too and where you have to enter the destination number.

Hello List - Here's the setup: Mediatrix 1102 ATA (t38enabled) <--> Asterisk 1.4.1 <--> IP <--> SIP GW <--> TDM The T38 call comes up perfect - I see the initial invite, followed by G711, Re-Invite, T38 establishes, Fax Completes, T38 Stops, Call Down. here's the problem - I see the following in my console: [Mar 19 05:09:38] WARNING[4745] chan_sip.c: Can't

Gentlemen, I have 3 faxes attached to an Asterisk. Fax - SPA2102 - Asterisk. 0851711201 and 0851711290 is on our WAN, no NAT. 0197673581 is outside our WAN and needs to be NAT'ed. Sending a fax from 0851711201 to 0851711290, no problem, switches to T38 and fax goes through. Sending a from 0197673581 to 0851711201, no problem as long as i dont enable T38 on 0197673581. But, if i enable T38

How can I get asterisk to work with faxes in my configuration? I have a WAN with Asterisk at the centre and Mediatrix 1104 gateways at the end nodes providing tone to legacy PBX's and fax machines. The Asterisk is connected to the PSTN via a Digium single port t1. The end nodes are connected via frame-relay 128kbps links. I want to use g.729 between the end nodes and the Asterisk box at

Hi, I remember seeing a T38 Gateway application for Asterisk 1.6 floating around, but I can't seem to find it again. Does anyone have any pointers to it? I really want to be able to send an incoming T38 connection directly to the PSTN. Thanks. -- James

Is it possible to force T38 for all invocations ReceiveFAX() ? Receiving fax always worked OK on Callweaver though I could put SipT38Switchover() into the dial plan. I can't with Digium fax, and it always fails at the point it decides to switch to T38.

Hi all.. Im using ABE C3.2.1 version and here Im having the following issue with respect to T38 fax calls. Somehow asterisk when it receives Session modification request with the T38 Codec, is not forwarding the request to the other end. Also asterisk is responding with 200 Ok to this RE INVITE with an audio line rather an media line with image. The session id here strangely matches to that of

Hi everyone, I have been trying to get T.38 Faxing to work with Iristel sip trunks for last few days but havn't been sccussful. I am using Asterisk 1.6.2.8 and SpanDSP 0.6.

Hi, I continue the discussion from https://issues.asterisk.org/view.php?id=19103 If T.38 reinvite detection should still work, why it doesn't? If I use faxdetect = t38 it does never detect the fax, even using alaw. Cheers, Darkbasic

Hi All, I'm in the lab with Asterisk 1.6.1.12 and several ATA's testing T38. I hit a snag with the Grandstream HT502. It only seems to nail up a session at 9600bps. The Grandstream GXW4104 nails up consistently at 14400bps. I'm using the same equipment in the same configuration, just switching out the ATA. I have the latest firmware on each unit. Any ideas on what could cause
