The Problem

Common Challenges for Businesses, telecoms resellers, and IT teams running their own VoIP and SIP infrastructure

These are the issues that consistently come up when Businesses, telecoms resellers, and IT teams running their own VoIP and SIP infrastructure try to scale on the wrong infrastructure.

Challenge 1

VoIP on shared VPS suffers from jitter and packet loss during CPU steal events - callers hear choppy audio, dropped words, and echo

Challenge 2

Cloud-hosted PBX solutions charge per-user or per-channel, making costs unpredictable as your business grows

Challenge 3

SIP endpoints on shared infrastructure are frequent DDoS targets - a single attack takes down your entire phone system

How We Help

How Glitch Servers Solves This

Voice over IP is latency-sensitive - even 50ms of additional delay degrades call quality noticeably. Jitter, packet loss, and CPU contention on shared infrastructure all translate directly into choppy calls, dropped audio, and frustrated callers. A dedicated server eliminates resource contention and provides consistent, low-latency networking for SIP trunks, Asterisk PBX, FreePBX, 3CX, or any voice platform. UK datacentre location ensures sub-10ms latency to UK SIP providers and PSTN gateways.

External resources: LINX (London Internet Exchange) and RIPE NCC (European IP registry).


A Glitch Servers dedicated server provides the consistent CPU, network, and I/O performance that VoIP demands. Install Asterisk, FreePBX, 3CX, or Kamailio with full root access. UK datacentre with direct LINX and LONAP peering means optimal routing to UK SIP trunk providers and PSTN gateways. DDoS protection guards your SIP endpoint against volumetric and SIP-specific flood attacks. IPMI access ensures you can reach your PBX even during a network issue.

What You Get

Built for Businesses, telecoms resellers, and IT teams running their own VoIP and SIP infrastructure

The features that matter most for your workload, included as standard.

Low-Latency Voice Quality

UK datacentre with LINX/LONAP peering delivers sub-10ms latency to major UK SIP providers. Dedicated CPU eliminates the jitter and packet loss caused by resource contention on shared hosting.

🛡

SIP DDoS Protection

SIP endpoints are high-value DDoS targets. Corero SmartWall mitigates volumetric attacks and SIP-specific floods (INVITE floods, REGISTER floods) at the network edge.

🔧

Asterisk / FreePBX / 3CX

Full root access to install any PBX software. Asterisk, FreePBX, 3CX, FusionPBX, or Kamailio - configure trunks, IVR, voicemail, and call routing exactly as your setup requires.

💰

Dedicated IP for SIP Registration

5 IPv4 addresses included. Use a dedicated IP for SIP registration that doesn't change - critical for trunk provider whitelisting and consistent NAT traversal.

FAQ

Frequently Asked Questions

Yes. FreePBX runs on CentOS/Rocky Linux with full root access. Install via the FreePBX ISO or on top of a minimal Linux install. All SIP, IAX, and PJSIP configurations are fully supported.
A Xeon E3 running Asterisk handles 100-200 concurrent G.711 calls or 50-100 G.729 calls depending on transcoding requirements. For higher capacity, Dual Xeon options scale further.
No. We do not block any ports on dedicated servers. SIP (5060/5061), RTP media ranges, and all other ports are open. You configure your own firewall rules via iptables or nftables.
