i have a UCM6104 installed with 3 phones running Peer SIP.
i replaced the internet provider recently with new WAN IP.
after changing to new IP, the inbound calls starts having problems.
every time calls come in, it rang on the phone for 2 times and message come out “your call cannot be completed as dialed”
but call can be answered, if pickup before 2 rings are end.
and outbound call are all fine.
do anyone have answer for this?
