Well this is a 2 X E5506 With 8 GB of Ram. The Main Problem is that we use tons of DTMF + TTS + Dialplan Logic and as you say Anthony this causes an impact on the total Supported Calls. I'm building a new IVR server that we can deploy on another server so we can ease the pain that mod_python is causing on the CPU. TOP Shows AVG idle CPU at 93 % Anyway for every performance increment i find i will post it here. Thanks Anthony for your input i think i got your point , I'm assuming an SBC with media bypass would handle a lot more calls per profile but as you may have guessed my objective is not SipTrunking but a high layer of service. Anyway thanks alot. Regards Antonio Teixeira 2011/5/24 Anthony Minessale <anthony.minessale@gmail.com>
Anything you find useful to get more calls is subjective to the power of the box. If sofia starts behaving badly, it indicates a maximum resource consumption. More profiles of course help with concurrency.
So I could have a box where I could do 5000 calls before another profile would help and someone else could get benefits of multiple profiles at 100 calls.
You have 2 choices: 1) Search for ways to squeeze more calls out of a bad box like we used to do with config.sys in DOS 2) Use the money you saved by getting a free carrier grade switch platform and buy a halfway decent box.

Regarding the SIgnaling Problem , the DB was already on tmpfs and you may have read that this was not an I/O problem.
To load Blance a call is simple in our use case.
First understand we use auto-dialers so alot happens in the backend , the rest we send a originate command so simply change the profile used imagine :
originate sofia/external1_profile/22222222@111.11.11.11 IVR XML
The dialer simply changes originate sofia/external1_profile/22222222@111.11.11.11 IVR XML originate sofia/external2_profile/22222222@111.11.11.11 IVR XML originate sofia/external3_profile/22222222@111.11.11.11 IVR XML originate sofia/external4_profile/22222222@111.11.11.11 IVR XML
We use INB ESL.
Now if you want to use "softphones" i think you can use mod_limit and the XML dialplan to create a realtime version of this.
Notes :
Keep in mind that i do not know if this is the correct way to handle this situation but we have it deployed this way and as i was able to increase the call volume by a factor of 2 while at the same time increasing quality and decreasing the signaling issues. At the expense of RAM more RAM = Profiles.

moving your SQLlite DB to tempFS is the biggest single change you can
have
with FS. that alone would account for the massive increase in calls you were able to achieve.

the only real improvment was to move your DB to tmpfs ... the rest (
if
64bit) makes really small difference from distro to distro..
