We're having random on-going problems with SIP, usually for 5 minutes or less a couple times at day at various locations. I'm not seeing any dropped packets in the connect events, and I've created a prefilter fastpath policy for this traffic. SIP is being inspected, and I was told today to make sure SIP ALG is disabled; however, I'm not sure where to do this at. I've not been able to track down documentation to do this within FMC. Can anyone point me in the right direction? Thank you.</P> Fri, 29 Jan 2021 21:23:40 GMT https://community.cisco.com/t5/network-security/problem-with-sip-trunk-random-connection-problems/m-p/4282500#M1077859 ABaker94985 2021-01-29T21:23:40Z https://community.cisco.com/t5/network-security/problem-with-sip-trunk-random-connection-problems/m-p/4282617#M1077864 <P>You need to access firewall console then issue the following command</P><P>configure inspection sip disable</P> Sat, 30 Jan 2021 05:53:24 GMT https://community.cisco.com/t5/network-security/problem-with-sip-trunk-random-connection-problems/m-p/4282617#M1077864 Massimo Baschieri 2021-01-30T05:53:24Z https://community.cisco.com/t5/network-security/problem-with-sip-trunk-random-connection-problems/m-p/4283606#M1077950 <P>We're using FMC, but you got me on the right track.
