The Messy Truth About Voice Costs
“Voice is dead.” Heard that one before? Probably as often as someone swore the fax machine was on its last legs. And yet—voice is still alive, still kicking, and still billing.
If you’re running SIP trunks, legacy voice contracts, or some hybrid UCaaS setup, chances are you’re paying for:
- Channels you don’t use.
- Services you don’t need.
- “Mystery fees” suppliers slide in, hoping no one blinks.
It’s not glamorous. But it’s happening every single month. SIP happens.
Why SIP Needs Attention
SIP (Session Initiation Protocol) isn’t just telecom jargon. It’s the plumbing of modern voice. The problem? Without proper visibility, it becomes a budget drain. We see it daily:
- Overprovisioning: Buying 100 channels when 60 would do.
- Billing errors: Invoices that don’t match the contract.
- Double billing: Paying for UCaaS and SIP when one would suffice.
- Rate neglect: Suppliers don’t rush to tell you when prices drop. Spoiler: they’d rather keep your money.
Where JOLT Fits In
At JOLT, we keep it simple: if you’re paying for it, it had better be correct.
- We audit every line item.
- We benchmark your pricing against the market.
- We recover overpayments (yes, actual cash back).
- We automate reporting so you see real usage, not supplier spin.
No gimmicks. No supplier bias. Just hard data and accountability.
The Payoff
One client discovered they’d been double-billed for over a year. Another found 30% of their “active” channels were as lively as a fax line in 2025. The result? Millions back in their pocket and a leaner, smarter voice estate.
Because SIP happens—but with JOLT, savings follow.
