Why Host VoIP Server on OMC Cloud

VoIP systems are uniquely sensitive to network quality. Even 30ms of added latency causes noticeable audio degradation. Jitter and packet loss make calls unusable. Your PBX infrastructure needs dedicated resources, low-latency connectivity, and DDoS protection.

OMC Cloud provides VPS optimized for VoIP across 24 global data centers — deploy your PBX in the region closest to your callers for crystal-clear audio. DDoS protection is included (VoIP servers are frequent targets), and NVMe storage handles call recording and CDR data without I/O bottlenecks.

Frequently Asked Questions

What VoIP software can I run?+

Any Linux or Windows-based PBX: Asterisk, FreePBX, 3CX, Issabel, VitalPBX, FusionPBX, Kamailio, and custom SIP applications.

How important is latency for VoIP?+

Critical. Audio quality degrades noticeably above 150ms round-trip. OMC Cloud has 24 data centers — deploy in the region closest to your callers for sub-20ms latency.

Is DDoS protection included?+

Yes. Network-level DDoS protection is included on all servers at no extra cost. VoIP servers are among the most frequently targeted services.

Can I record calls?+

Yes. NVMe storage provides fast I/O for real-time call recording. Automated backups protect your recordings with 14 daily restore points.

How many concurrent calls can I handle?+

Depends on codec and configuration. On 4 vCPU / 8 GB RAM, expect 25-50 concurrent G.711 calls or 50-100 G.729 calls. Scale up for more.

Can I use SIP trunking?+

Yes. Full network access with dedicated public IP. Configure any SIP trunk provider — no NAT issues, no firewall restrictions.

Is there E911 support?+

E911 is handled by your SIP trunk provider, not the hosting infrastructure. OMC Cloud provides the reliable VPS; you connect your preferred trunk.

Can I set up failover between regions?+

Yes. Deploy servers in multiple data centers and configure SIP failover. Our team can assist with high-availability PBX architectures.
