Lag and delays on App Phones and Cell Devices

[Johnnie94]

Zoom, mostly the issue is answering from the mobile app. It may not answer an incoming call or send an outgoing call. This is also an issue from desk phones too. Common issue are as follows: 

• Delays when connecting inbound and outbound calls

• Incorrect caller ID displays when multiple calls come in , and multiple team members answer

• Inconsistent tracking of who actually answers the call (e.g., if I answer, it sometimes shows a different team member)
• Voicemails being left indicate a verbal time 12:47 a.m. and the call log indicates 2:47 a.m. (Reporting appears to be in a different Time Zone than what Site is set too.
