VOIP incoming calls problem
I have around 60 VOIP Polycom Phones, and after I look Pfsense SIP rule settings sticky, I feel like there are still something missing in my end.Because Phones can make outgoing calls however, 5-6 phones out 60 phones work for incoming calls in certain amount of time, then they stop working, then other 5 phones start working then , they stop working.Meaning some random phones work short amount of time for incoming calls then they stop working.
So Far I configured following NAT settings and also on Rules I put the STATE TYPE to NONE. Obviously I am still missing something.
Protocol Source Port Destination Port Gateway Queue
TCP/UDP * * voip 5060 (SIP) * none
TCP/UDP * * voip 10000 - 20000 * none
TCP/UDP * * voip 2222 - 2268 * none
TCP/UDP * * voip 123 (NTP) * none
voip, defines an alias for the IP address range that phones have.
I appreciate for your time and answers
I think the state type needs to stay at Keep State. The phone send a keep alive signal every so often. This is meant for NAT system with state keeping.
Are you using Manual Outbound NAT?
Is "Firewall Optimization" set to "Conservative"?
I have 8 sites running Polycom phones and this is all I've ever had to do to get them running. No added rules.
I am using both manual outbound NAT, but my optimization is set to normal. I am running Cisco phones. I have heard that polycom phones are more forgiving.
