Zoom Phone - No Inbound Audio - Poly edge E220
We recently setup Zoom phone for our Corporate HQ in Singapore and we are having issues with Inbound audio on a physical phone will receiving a call from an external Dialer.
I am going to summarize and can provide PCAP if helpful
Provider : Singtel
Connection Type: Provider Exchange(OTT Private Data Center)
Physical Device: Poly Edge e100/220
We have an open support case with Zoom but hoping to have community support to assist with faster resolution. We have checked all firewall port settings required for Zoom phone and validated they are opened as needed. We have swapped to new phones of the same model but having the same issues. We moved the phone number from a Common area account to a user account(logged into a computer) and they have ZERO audio issues.
I know I might be missing some helpful details but can fill in the blanks if anyone has thoughts of things to check.
