Hey, quick question. I'm setting up a BYO SIP trunk with a carrier (from Honduras), and they already allowlisted Vapi’s SIP IPs (

44.229.228.186

and

44.238.177.138

). Now they’re asking for the exact SIP

User-Agent

header that Vapi’s SBC sends so they can whitelist/permit it on their side. Do you know what

User-Agent

string Vapi uses for outbound SIP traffic / SIP registration? And is it a fixed value, or can it vary by region/infrastructure? I've searched through all docs and couldn't find anything about this. Thanks 🙏
