Businesses choose call avoidance techniques because person-to-person service calls are time-consuming^{[citation needed]} and costly^{[citation needed]} and should be accessed only when there is no viable option. Voice calls can then be reserved for high priority customers, complex service requests, or emergency situations where the quick response of skilled phone agents is essential.

It is impractical^{[citation needed]} and expensive^{[citation needed]} for call centers to provide a live answer for every caller during peak demand periods such as certain times of the day, days of the week, or seasons. Callers in urgent need to discuss an issue with a live person are typically put on hold along with callers whose request could be better served through other channels. Both are competing for valuable talk time.

With the spread of the Internet and email access, contact centers are moving toward self services^{[citation needed]} via a searchable knowledgebase, Interactive Voice Response (IVR), or computer generated emails. Password resets are the most popular^{[citation needed]} form of website self-service where clients are asked pre-established confidential questions that verify credentials before the system sends them a temporary password. Other typical areas to employ call avoidance strategies include the following:

• Voice message indicating wait times, unusual activity, downtime, etc.
• Web forms that gather pertinent information before a call is answered
• Electronic chat via the Internet
• Online software update notices of upgrades to prevent security or virus breaches
• Blogs, Frequently Asked Questions (FAQ), web site links to common problems
• Simpler, clear and concise product documentation and descriptions
• Automatic return policies and procedures
• Reports that identify key problem areas for corrective action, i.e., additional instruction/training

• Call centre
• Help desk
• Helpdesk and incident reporting auditing
• Incident tracking system
• Service desk (ITSM)
• Technical support
• Customer service
