Based on the provided information, it appears that the caller with the number +17085231738 is likely a telemarketer or scammer since the call went straight to voicemail and was full, indicating a possible attempt to leave a mass message or automated voicemail. The fact that the call was not answered and the voicemail was full suggests that the caller may be using robocall tactics to reach a large number of people. This behavior is consistent with spam calls, which often involve automated dialing systems and pre-recorded messages.
