Do you mean "implementation" in the context of Kamailio's implementation of
SIP? If so, what if certain SIP clients implement it in a different way and their Tag
values exceed this limitation?

Hello,
Is there a maximum length/size defined for the From and To Tag?
The RFC states: “it MUST be globally unique and cryptographically random with at least 32
bits of randomness”.
Though I can’t find anything in the RFC about the maximum.
The sip_capture table stores the to_tag and from_tag in a varchar(64). Does this mean the
max is 64?

Yes, that's an implementation's limitation.
