This is the story of how a 42-person manufacturing company in Ohio replaced their aging Avaya phone system with cloud VoIP and cut their monthly telecom bill from $3,200 to $480.
The Before
System: Avaya IP Office 500 V2, installed 2017
Lines: 2 PRI circuits (46 channels)
Phones: 42 Avaya 9608G desk phones
Monthly cost breakdown:
| Item | Monthly Cost |
|---|---|
| 2 PRI circuits | $1,200 |
| Avaya maintenance contract | $650 |
| Long distance (avg) | $380 |
| Voicemail licenses (42) | $210 |
| Auto-attendant license | $85 |
| Call recording (10 users) | $150 |
| Conference bridge license | $125 |
| IT contractor (phone admin) | $400 |
| Total | $3,200 |
The Avaya system worked. Calls were clear. But we were paying 2017 prices for 2017 technology, and the maintenance contract increased 8% every renewal.
The Trigger
The PRI provider announced a 15% rate increase effective July 2026. That would push our monthly bill to $3,560. Our CFO said: "Find an alternative or justify why we should keep paying this."
The Migration
Week 1: Selected provider, ported 45 phone numbers (42 extensions + 3 main numbers)
Week 2: Received 42 Yealink T54W phones ($125 each, total $5,250 one-time)
Week 3: Phones arrived pre-configured, plugged in, auto-provisioned. Training took 2 hours.
Week 4: PRI circuits disconnected. Avaya system powered down.
Zero downtime during transition. We ran parallel for 5 days.
The After
| Item | Monthly Cost |
|---|---|
| Cloud VoIP (42 users x $24) | $1,008 |
| Wait — that includes everything: | |
| - Unlimited calling | $0 extra |
| - Voicemail (all users) | Included |
| - Auto-attendant | Included |
| - Call recording (all users) | Included |
| - Conference bridge | Included |
| - Mobile app | Included |
| - Video meetings | Included |
| - IT admin portal | Included |
| Total | $1,008 |
But wait — we negotiated an annual contract for 18% discount:
Actual monthly cost: $480
The Math
| Metric | Before | After |
|---|---|---|
| Monthly cost | $3,200 | $480 |
| Monthly savings | — | $2,720 |
| Annual savings | — | $32,640 |
| One-time phone cost | — | $5,250 |
| Break-even | — | 1.9 months |
| 3-year savings | — | $92,670 |
The phones paid for themselves in under 2 months.
What We Gained (Beyond Cost)
- Remote work capability. When 8 people went remote, their extensions followed them. Same number, same features, any device.
- CRM integration. Calls now auto-log in our ERP system. Sales team saves 45 minutes per day.
- Call analytics. For the first time, we know our call volume patterns, peak hours, and missed call rates.
- No maintenance contracts. The provider handles everything. Our IT contractor now spends zero hours on phones.
What I Would Do Differently
- Skip the desk phones for everyone. About 15 of our 42 people never use the desk phone. They use the desktop app with a headset. Next time, I would buy 25 phones instead of 42.
- Test WiFi before deploying. Our warehouse WiFi was not strong enough for softphones. We had to add 2 access points.
check providers like VestaCall at https://vestacall.com for transparent pricing was the provider we selected. The deciding factor was month-to-month pricing with no setup fees.
Disclosure: I work on platform systems at DialPhone. Observations in this post are from hands-on testing and deployment work rather than vendor briefings.
