Fax Problems with SpanDSP
Hi list, I'm running current SpanDSP http://www.soft-switch.org/downloads/spandsp/spandsp-0.0.4pre6.tgz with Asterisk 1.2.22 somewhat successfully.

Anyone have a reliable T.38 Solution
Aloha, We are looking to roll a solution that will have the following network layout: ISDN-PRI <--> Asterisk <--> T.38 <--> ATA <--> Fax Does version 1.8 with the Digium fax driver have this capability? I like 1.8 because it is a long term support version. What ATA's are people using? Any working solutions would be great! Aloha, Matt

Polycom wideband codecs?
Doing a little research before Friday's Voip Users Conference call with Dan Behringer. Are any of the newer Polycom wideband codecs implemented in v1.6? Specifically, G.722.1 or G.722.2?

Algorithmic Delay
Hi, I was hoping to get some clarification on the meaning of algorithmic latency in Speex. For wideband signals, algorithmic delay is specified to be 34 ms (20 ms is the frame size and 14 ms is the lookahead). Does this number (34 ms) account for the double-buffering on the input? Assuming that the computation time and sound wave propagation time are negligible, should I expect compressed

Fw: Asterisk R2 Signaling

A software FAX modem
Hi all, I would like to announce the availability of an initial test version of a totally software FAX facility, suitable for use with Asterisk. This is a first public test release, so don't expect a solid polished product just yet. People have shown interest in what I am doing, and here is the evidence that it is not vapourware. If the notion of a software FAX machine is new to you,

Is there any MFC-R2 implementation for asterisk?
The last thing that I read about it was: Steve Underwood [steveu@coppice.org] wrote on Sep 3: >> Is E&M designed to work with the E1 driver code? I think probably not.

Still on spandsp/app_fax and T.38
This message is pointed directly to Steve Underwood. I tought it would not be nice to directly email him with a question that interests a good part of the Asterisk community, so here it is. :) Steve, remember a few days ago when we discussed about issues on Asterisk 1.6.1.13 and T.38 fax reception? Well I opened an issue on Mantis (https://issues.asterisk.org/view.php?id=16756) and turns out it

Text entry by DTMF
Hi, I've kind of ported a DTMF text extry method I wrote some time ago for Dialogic. It is now a semi-working Asterisk app. I've still got to clean up some stuff in how Festival is used to read back what is entered, and then I think it should be OK. Would anyone here find this useful? It takes an entered string, and returns it as a variable. It might sound clunky, but for short entry

Are the Siren7 and Siren14 the G.722 HD voice codecs?
Hi Everyone, 1- Are the Siren7 and Siren14 the G.722 HD voice codecs? 2- Are these codecs only for Polycom units or are they universal across all other SIP phones that advertise the HD voice codec like Aastra? 3- What is the main difference between the two and is it advisable to run these over the INTERnet (not INTRAnet)?

SS7 signaling/Softswitch
I'm confused a bit about the following and was hoping to get some answers on this group - What is exactly implied when we say asterisk can connect to a PSTN. Does it mean connecting to the PSTN via PRI/T1/E1? If yes, then I assume asterisk does not need to do any SS7 signaling and all it does (playing the role of a PBX) is to connect to a Class 5 Switch at the CO. Is this a correct statement?
