Does Pfsense Support Alg?

Re: SIP / ALG
There is no such thing in pfsense. Its NAT related.

Should I enable or disable SIP ALG?

You should disable SIP ALG because it: Interrupts SIP traffic like calls and conferencing apps. Affects the perceived reliability of desk phones and VoIP apps. Isn't needed when using cloud-based VoIP providers.

Is ALG necessary?

ALG services are necessary so that devices can open ports dynamically in their firewalls to permit data packets through and assign the correct Aerohive QoS class to the data traffic.
