Final answer:
The statement is true; telephone communication's main drawback is the absence of face-to-face interaction, which can impact the depth of the business relationship and communication effectiveness.
Step-by-step explanation:
True, one disadvantage of telephone communication is the lack of face-to-face contact with the customer. This affects the personal connection that can be critical in business communications. Other affecting factors include increased use of caller id, decreased use of landlines, and the hectic nature of personal schedules. Moreover, bias in phone communication may arise because not everyone has a telephone, and cell phone numbers are frequently unlisted in directories, hence affecting the representativeness of any survey done via telephone. Furthermore, with the advent of technology, many people find non-voice messaging apps or texts more comfortable, especially among young people. This illustrates the evolving landscape of communication where direct voice communication is often seen as intrusive as opposed to texting or messaging.
