1. Hello, I would like to know what is need for press one campaign for call center with 50 to 100 people will I need to cluster vicidial. To make press one campaign run smoothly with no issues of enough lines to agent

2. how many lines per agent will be need to run a very fast and smooth press one campaign that will have no latency.

Press one campaigns come in many flavors and sizes. We have had them range from 10 lines per agent to 100 lines per agent.

You will need enough bandwidth to hold the total lines you are actually dialing (which cannot be calculated reliably based on the information given ...).

You will likely need a rather large cluster or several independent machines, possibly with 200+ Meg of bandwidth available if you intend to have that large of an office. If you do not have serious bandwidth available, consider colocating your servers or using a facility like Vicihost where they lease you the servers. We also do this at poundteam, of course.

To do this with conventional leased line channels, you would get 23 lines per T1 ... and likely need anywhere from (50 agents X 10 lines each =) 500 lines which is over 20 T1s (at approx $200 each T1 per month). More likely you'd go with a T1 which would likely be half that cost. But that quantity of T1s or a T3 would likely take 6 months to install and incur a hefty contract.

On the other hand, with pure internet *SIP* trunks, you need just Lots of Bandwidth. 500 lines is 50M service uncompressed, 15-25M compressed. And if you use colocation, you need only 50 lines (1 per agent) to reach the colocation facility, and the colocation facility would then supply the connections outbound. This still costs $$, but most colo facilities will charge a premium for a small connection, but as your bandwidth usage increases, the cost only increases a little bit. (After the overhead is cleared, things get much cheaper).

At that point it depends on how many lines you require per agent (10? 100? between?) and how many agents you actually "seat".
