The caller with the number +19289689312 is likely making unsolicited calls, which has led to a scam suspicion. The caller's behavior is considered invasive, as they are making unwanted calls to individuals. Based on the comments, it appears that the caller is not leaving messages or providing any useful information, leading to frustration among the recipients. The suggestion to stay on the line to gather more information is not practical, as the caller's intention is unknown and may be malicious.
It would have been more productive if the caller had remained on the line to discuss the purpose of their call.
Receiving a spam call from this number, I immediately hung up.
