@bnrstnr SIP-ALG in ISP provided gear is nearly universal.

Guh, who would have thought... Is SIP-ALG purely sabotage or is it useful in certain scenarios?

Actually sabotage. Ubiquiti is the only vendor that I know where it works most of the time.

Most firewall vendors are also either phone companies or in bed with phone companies and have a huge interest in convincing people that other phone products don't work reliably.
