Dear QBZappy
How do you get G729 codec working ?
I am using ObiOn PC at home to call an Obi110 in the office and through it's PSTN line. I configure the settings remotely via ObiTalk.
I went into Obitalk and unchecked the 'enable' box of G711U, A, and all the rest of the codec and left G729 enabled. But when using Softphone dialling through ObiOn PC, it would ring, connects and then disconnects quickly. The Call Status would show that there is no Tx/Rx as shown
This is a working call, using default Codec Profile A (with G711U)
The only lowest codec I could used was G726R32 (sounds okay)...if I try G726R24 and anything lower, same hangup issues.
Thank you

Both sides of a voip call need to use the same codec. A call to PSTN can not use 729 unless the server can transcode the call in progress. I don't think the OBi has this ability. 711 codec is the base line codec for PSTN and Google voice.

Another way to control the codec selection is when making a voip call you can prioritize the codecs without disabling any of them. If you look in the OBi wb page in the "Codecs" section you see a control for "Priority". You can select the order you would like to try or disable it completey by unchecking the enable box above. Althought I never use it, I think you can also prefix the dialed number so that it is forced using a specific codec.
Stewart:
I am guessing that the softphone you are using does not support G.729. However, why do you want to use a compression (lower quality) codec? Are you unable to get a fast Internet connection? Have a connection with a high usage cost or very low bandwidth cap? Having a voice quality issue that you believe may be mitigated with a compression codec?
Ideasmiths:
I am just testing the various codec as I just completed the setup. I have 2xObi110, one in my home and the other in the office. My test is now using the ObiOn PC and Softphone to call the office Obi110 and use the PSTN. My assumption was that ObiON (if have G729) would connect with the Obi110 (G729) and everything should works?
Updated: You are correct, the NCH softphone I am testing do not support G729....back to the drawing board....
At this moment, I am guessing that the network in my office is congested/high latency etc because when I use the G711u, sometimes the other party complain that my voice is choppy. When I enabled only the G726R32 codec, the communication was smoother. I want to see if I can try G729 to further improve the choppiness and giving up some voice quality.
It is strange that I cannot enable G726R40 or G726R24 or G726R16 or G729. Could it be that ObiON PC software is stuck with only G711u codec? I'll try using my home Obi110 (G729) to call the office Obi110(G729)....
Thank you for your ideas
