Calls Failing at 32 Seconds


All the calls on the Switch are failing at 32 seconds. Below is the screenshot. Please let me know what i am doing wrong.

This is not yeti issue - remote gateway didn’t send ACK.

@amitiyer could you show pcap trace?

Yes, please find the pcap link.

I checked trace and I was rigth - call originator didn’t send ACK on INVITE transaction. Looks like call originator doesn’t receive any packets from yeti.

how can this be solved ?

This is network issue - Traffic from yeti is not reaches origination gateway. Try to check your firewalls.
