When the same codec is used, g711a, Speex, iLBC or GSM, we can see that the largest number of simultaneous calls that supports the Asterisk PBX is linked to the number of bytes required to transmit information of voice, a less complex voice codec, consume higher bandwidth to transmit voice information. In the case of using the. I use ILBC codec in the trunk. Btw: I use asterisk-1.2.12, zaptel-1.2.8: Elmer (elmer at diavox dot net) 06 September 2006 14:52:40 Hi, I am new to asterisk and linux. I installed asterisk and already configured SIP extensions and IAX. I made some calls already from a hard phone to E-lite and vice versa. Asterisk Codec Configuration The Sangoma transcoder will perform transcoding for all codecs listed in the codec module configuration file: sangomacodec.conf. By default, the codec module is already pre-configured to perform all codec translations for G729. If you require only g729 translations you do not need to edit any information.

1. While the wiki calls out iLBC as being supported, that codec does not appear in the list of translators?

You will have to enable iLBC in the Asterisk Sangoma codec configuration file.
Asterisk has bug that if you try to register 2 of the same codec it will crash :)
For that reason we are very careful as to what we include automatically.
You will have to edit the asterisk sangoma config file and enable iLBC (register=ilbc).

The same apply for any codec other than G729, by default only G729 is enabled in Asterisk and FreeSWITCH.

2. When using the transcoder why do I hear no audio?

If you are hearing no audio during calls when the transcoder is being used, use the following command to determine if Asterisk/FreeSWITCH is processing Tx and Rx packets with the transcoder:

->Asterisk users:

->FreeSWITCH users:

If only the Rx packets are not incrementing, this means that the Tx packets are being sent to the transcoder, but the processed packets are not being returned back to Asterisk/FreeSWITCH. This scenario occurs when the Vocallo module inside the transcoder cannot find a real IP address for Asterisk/FreesWITCH in which to return the Rx packets to, and uses the local host address 127.0.0.1. The result is Rx packets being looped back to the vocallo module. To verify the local host address of your system ping $(HOSTNAME).

If the local host address of your system is 127.0.0.1, this issue can be resolved simply by editing the file:

->Asterisk users:

->FreeSWITCH users:

->Asterisk Users:

In the file add the following line:

-> rtpip= <network interface chosen for transcoder> (i.e. rtpip=10.1.1.1)

This will send the Rx packets up to the network interface of the transcoder, then Asterisk/FreeSWITCH will be able to receive the packets.

The final step is to reload the sangoma codec module in the CLI

->FreeSWITCH users:

In the file add the following line:

-> <param name='rtpip' value='10.1.1.1'/>

This line needs to be added in the <settings> tag of the xml file. See below for an example config.

3. Why does Asterisk crash during load time when using the transcoder?

If Asterisk encounters a codec being registered with a lower cost than one that already exists, it will crash with segmentation fault. This scenario occurs due to a bug in Asterisk, with more information provided here: http://issues.asterisk.org/view.php?id=17092.

The sangoma translator module is designed to prevent such an issue, only if it loads AFTER asterisk codec translators. Make sure that 'codec_sangoma.so' located in /usr/lib/asterisk/modules/ loads after all other codecs in that directory.

However, an easier way to resolve this issue, is to have Asterisk never load the translation paths that will be provided by the sangoma translator.

All Asterisk codecs are located in:

In order to do this edit:

and create 'noload' lines for all asterisk translator paths. (i.e. noload=>codec_g722.so)

Once Asterisk is restarted, in the CLI, you can type 'module show like codec' to view all other codecs loaded by asterisk

4. Why does Asterisk stop responding shortly after loading?

If Asterisk stops responding shortly after loading, it could be an issue with the firewall settings on your system. By default, the sngtc server is configured to listen on all network interfaces, however if you decide to specify the interface for the sngtc server, then the firewall must allow for communication between the sngtc server and the client (Asterisk/FreeSWITCH).

To check how the sngtc server is configured, run:

If you have not changed the default configuration, then the output of the above command should indicate that the sngtc_server is listening on 0.0.0.0. If the sngtc server is listening on another port, then make sure that port is allowed through the firewall.

If the issue persists after checking the above, the firewall might still be causing the issue, at which point, all firewall entries should be cleared. To check all firewall entries run:

To clear all entries in the firewall run:

then run

once more to confirm all firewall entries are cleared

Then restart Asterisk to determine if the issue is resolved

5. After installing the D100 PCI express card, I get NMI debug messages on my system

After installing the D100 PCIe card, if you notice system debug messages that say: 'Uhhuh. NMI received. Dazed and confused, but trying to continue', this is due to parity error. To resolve this issue, simply download and install the latest tg3 broadcom ethernet driver found here: tg3-3.112d.tar.gz

Reboot the system after the install

6.Why can't I start asterisk after setting up the Transcoder?

After installing the transcoder, asterisk may fail to load. After checking the asterisk logs (/var/log/asterisk/messages) you see the following messages:

ERROR[8124] res_config_ldap.c: No directory URL or host found
ERROR[8124] res_config_ldap.c: Cannot load LDAP RealTime driver.
ERROR[8124] codec_sangoma.c: Refusing to load this module with non-dahdi timing, please disable all res_timing_*.so modules and leave res_timing_dahdi.so as the only timing source in modules.conf
ERROR[8124] codec_sangoma.c: You can load this module with other timing sources by setting allownondahditiming=yes in sangoma_codec.conf general configuration section

To resolve this issue, follow either of the following two steps:

Edit modules.conf (typically located in /etc/asterisk/) and either comment out or create 'noload=>' entries for all res_timing_*.so modules, accept for res_timing_dahdi.so.
Edit sangoma_codec.conf (typically located in /etc/asterisk/) and create an entry 'allownondahditiming=yes'

Then asterisk should load properly and all the codecs registered by the transcoder will begin to load

7. Why does the output of 'core show translation' in the Asterisk CLI indicate 999999 for the particular codecs I have enabled through the Sangoma transcoder?

If the output of 'core show translation' in the Asterisk CLI indicates '999999' for all transcoding paths responsible by the Sangoma transcoder then the sngtc_server is not running.

You will also notice messages in the asterisk logs (/var/log/asterisk/messages):
