1) Welcome to the Party!
2) As you are obviously new here, I have some suggestions to help us all help you:
When you post, please post your entire configuration including (but not limited to) your installation method and vicidial version with build.
This IS a requirement for posting along with reading the stickies (at the top of each forum) and the manager's manual (available on EFLO.net, both free and paid versions)
You should also post: Asterisk version, telephony hardware (model number is helpful here), cluster information if you have one, and whether any other software is installed in the box. If your installation method is "from scratch" you must post your operating system and should also post the .iso version from which you installed your original operating system. If your installation is "Hosted" list the site name of the host.
If this is a "Cloud" or "Virtual" server, please note the technology involved along with the version of that techology (ie: VMware Server Version 2.0.2). If it is not, merely stating the Motherboard model # and CPU would be helpful.
Similar to This:
Vicibox X.X from .iso | Vicidial X.X.X-XXX Build XXXXXX-XXXX | Asterisk X.X.X | Single Server | No Digium/Sangoma Hardware | No Extra Software After Installation | Intel DG35EC | Core2Quad Q6600
3.
IBM System x3650 M4
This has no meaning here. We would prefer to hear how many cores (processors, cpus ...?), the speed of the CPUs, how much RAM, the speed of the RAM, and the speed of your internet connection (up and down are both necessary, just download speed means nothing).
4. In many cases this can result from ANY of the requested specs from #3 above. In the case of hardware (CPU/Memory), it can often be resolved with better hardware. If the problem is bandwidth, however, and you do not have more bandwidth available, you could look at using a hosted service. The Vicidial Group offers this service along with many other facilities (including, of course, PoundTeam!). Then you would only need enough bandwidth to get your agents to the server, all the calls to prospects would generate from the hosted server with no impact on your network connection. This also allows for multiple locations for your agents to all use that same hosted server.
Happy Hunting!
