Marketing agency (telemarketing) seeks call center software for outbound calls

We are a marketing agency (telemarketing) and are looking for call center software for outbound B2B communications.

We have the following requirements for the tool:

• It should be able to control a classic telephone system, as we have had very bad experiences with VoIP in terms of voice quality, etc.
• It should have an email sending function.
• It must also be possible to send emails per project and per customer with a separate email account for the agent in question (neutral company domains or individual domains).
• Automatic dialing
• Follow-up management
• Reporting – for daily, weekly, and monthly results
• Statistics functions – for daily, weekly, and monthly results
• No MS Exchange Server is required.
• Windows compatible

Twenty software workstations are planned based on the concurrent user principle.
