VOIP Phone calls drops
-
Dear all,
After we update one hr to the latest Pfsense our VOIP internal phones are dropping calls for 10 second . so when we are talking to a customer the phone call drops for couple of second and restore, so the conversation is not to follow on both sides.
on the LAN side we are had always used any to any rules and no rules on the WAN.
The firewall is Conservative .
The PBX is hosted at the provider external in this case. we never had any issues at all before untill the updates.on the PfTop it does shows the IP of the PBX with State of MULTIPLE:MULTIPLE.
77.60.91.250 is our WAN IP
66.200.164.30 is the PBX IP where the SIP request coming from.pfTop: Up State 1-166/166, View: default, Order: age PR DIR SRC DEST STATE AGE EXP PKTS BYTES t udp In 10.10.56.43:2051 66.200.164.30:5060 MULTIPLE:MULTIPLE 25:21:48 00:00:57 13389 4140858 udp Out 77.60.91.250:33041 66.200.164.30:5060 MULTIPLE:MULTIPLE 25:21:48 00:00:57 13389 4140858 udp In 10.10.56.83:2051 66.200.164.30:5060 MULTIPLE:MULTIPLE 25:21:39 00:00:51 13726 4361107 udp Out 77.60.91.250:61763 66.200.164.30:5060 MULTIPLE:MULTIPLE 25:21:39 00:00:51 13726 4361107 udp In 10.10.56.83:2048 66.200.164.30:5060 MULTIPLE:MULTIPLE 25:21:39 00:00:54 7858 3452671 udp Out 77.60.91.250:19679 66.200.164.30:5060 MULTIPLE:MULTIPLE 25:21:39 00:00:54 7858 3452671 udp In 10.10.56.34:5060 66.200.164.30:5080 MULTIPLE:MULTIPLE 25:21:37 00:00:53 7890 3984866 udp Out 77.60.91.250:47441 66.200.164.30:5080 MULTIPLE:MULTIPLE 25:21:37 00:00:53 7890 3984866 udp In 10.10.56.38:5060 66.200.164.30:5080 MULTIPLE:MULTIPLE 25:21:13 00:00:42 7444 2757788 udp Out 77.60.91.250:27883 -

@cyberbot said in VOIP Phone calls drops:
77.60.91.250
Make a WAN rule with your service providers IP as the source and your client devices as the destination.
What RTP does your service use?
