Budget estimate

$200,000 – $1,000,000

No explicit budget is disclosed; however, municipal SIP trunking projects of similar scope typically range from a few hundred thousand dollars to low‑single‑digit millions, depending on the number of trunks, bandwidth, and support commitments. Assuming a moderate deployment with maintenance for a multi‑year term, a reasonable estimate is $200,000 – $1,000,000.
