The problem in plain terms.
Legacy PBX systems are expensive to maintain, impossible to scale, and completely isolated from your collaboration tools. When a remote employee wants to transfer a call to a colleague, they have to walk to their desk. When someone calls the main line while the receptionist is at lunch, calls disappear. Your phone system is costing you credibility — quietly.
We had three offices and three different phone systems. Inter-office calls required dialing external numbers. XAV moved everything to Teams Calling. Now we have one number, one system, and we cut our monthly telecom bill by almost a third.
Voice that works with your stack.
Microsoft Teams calling plans and certified desk phone deployments
Unified communications: one number, reachable on any device, anywhere
Auto-attendants, hunt groups, call recording, and analytics
Multi-site deployments — same system, same experience across all offices
SIP trunking and carrier selection — we handle the complexity
Typical use case
Professional services firm, 3 offices
A firm running three separate legacy PBX systems — each configured differently, each requiring its own IT support. Inter-office transfers required dialing external numbers. Voicemails weren't accessible remotely. After XAV unified them on Microsoft Teams calling:
Results
- ✓
Three offices on one system — managed from a single admin portal
- ✓
Employees reachable on mobile, desktop, or desk phone — same number
- ✓
Receptionist coverage configured across time zones with auto-attendant
- ✓
Monthly telecom costs reduced by 34% through SIP consolidation
This is our phone situation.
