What mean to say what is the size limit per conference? how many voice callers can one meeting handle? I get that is a limit of 50 video callers during a conference meeting but can that be more with voice callers? what is my limit?
Maximum Call Size is determined by your subscription plan, with 50 Max Call Size available to Enterprise subscriptions such as yours. For reference, see the following link: Lifesize Cloud Pricing & Subscription Information
This Maximum Call size is the total number of unique callers, whether they be a registered user, guest, 3rd party endpoint, or voice call. So you could have a call with any combination of these, up to 50 total. For Premium and Core plans, see the maximum call size referenced in the link above.
For enterprise customers the maximum amount of participants is 50 regardless of their technology (PSTN, thick client, web app, third party H.323/SIP, or Skype for business)
