T.38 gateway patch against Asterisk 1.8.11.0

Report
Question

http://www.linuxsystems.it/2012/03/new-t-38-gateway-patch-against-asterisk-1-8-11-0/ I made a new patch from irroot's branch and I ported it to 1.8.11.
Unfortunately latest one is still against 1.8.8 and porting from
subversion is quite time consuming, hopefully my work will be useful to
someone else.
Today I had no time to properly test it, so feedbacks are welcome.
Squeeze debian packages with t38 gateway will follow. Cheers,
Niccolò

meetme with timerfd

Report
Question

We use MeetMe with res_timing_dahdi as the timing source, and once a while we get the following error which then causes Asterisk to crash/restart (with safe Asterisk). ERROR[6518] res_timing_dahdi.c: Failed to configure DAHDI timing fd for 0 sample timer ticks
According to the following from Asterisk wiki, DAHDI is required for MeetMe. "Some confusion has arisen regarding the fact that non-DAHDI timing interfaces are available now. One common misconception which has arisen is that since timing can be provided elsewhere, DAHDI is no longer required for using the MeetMe application. Unfortunately, this is not the case. In addition…

Question

Hi,
I've some problem setting up Asterisk 1.8:
the configuration of the server is
8 core Intel(R) Xeon(R) CPU E5310 @ 1.60GHz
4GB of ram

the file "uac_pcap_G729.xml" just establishes a call, wait 120 seconds
and hangup. Finally the problem is: I cannot manage more than 80 concurrent calls.
but I know that is a limit too low, the same machine in the production

How to force codec transcoding?

Report
Question

Hi, we are working on a new codec for asterisk. It's early stages and
the main goal is just to be able to "hear it" using normal client end
points. So what I want is to be able to take a couple of normal G711
extensions, but have asterisk internally force a transcode to my new
codec. In this way we can easily run up a bunch of listening tests with
a wide variety of users very easily Ok, so how do I force this transcode in the middle, ideally without
using two asterisk…
