 |
|
Hello,
I've got a problem at the moment, that setting "transmit_silence = yes"
seems to have no effect on Asterisk 1.8-Certified.
Although it's enabled and "core show settings" confirms, that it is
really enabled, there are no RTP packets sent by Asterisk when waiting
for DMTF input or when "Wait()" is called.
Also, there seems to be a small gap of 2 or 3 not sent packets when
playing several files one after another.
At the moment I'm using Asterisk 1.8 Certified (Cert 5).
In asterisk.conf I've set:
highpriority = yes
languageprefix = yes
internal_timing = yes
defaultlanguage = de
transmit_silence = yes
transcode_via_sln = yes
documentation_language = en_US
"core show settings" says:
PBX Core settings
-----------------
Version: 1.8.15-cert5
Build Options: DONT_OPTIMIZE, LOADABLE_MODULES,
BUILD_NATIVE, G711_NEW_ALGORITHM, G711_REDUCED_BRANCHING, TEST_CODING_TABLES
Maximum calls: Not set
Maximum open file handles: Not set
Verbosity: 8
Debug level: 0
Maximum load average: 0.000000
Minimum free memory: 0 MB
Startup time: 21:29:18
Last reload time: 21:29:18
System: Linux/3.2.0-4-amd64 built by root on
x86_64 2014-05-24 18:42:53 UTC
System name:
Entity ID: 00:25:xx:xx:xx:xx
Default language: de
Language prefix: Enabled
User name and group: xxxx / xxxxxxx
Executable includes: Disabled
Transcode via SLIN: Enabled
Internal timing: Enabled
Transmit silence during rec: Enabled
Generic PLC: Enabled
Is there anything I could do for forcing transmitting silence without
stopping sending RTP packets?
Maybe this would solve the "issue" with the packet gaps between
playbacks also.
Greetings
Max

Without looking at a DEBUG log, I'm not sure what anyone can tell you.
Wait does call ast_safe_sleep_conditional, which enables a silence
generator on the channel if (a) there is no generator on the channel
and (b) ast_opt_transmit_silence is true (which it should be based on
your configuration):
/* If no other generator is present, start silencegen while waiting */
if (ast_opt_transmit_silence && !chan->generatordata) {
silgen = ast_channel_start_silence_generator(chan);
}
Starting a silence generator should emit a debug level 1 message
indicating that it has started. If your log doesn't show that, then
there may be another generator present that is preventing silence from
kicking off.
