At Hexabyte Systems, we provide certified, end-to-end IP phone setup, extension provisioning, SIP registration, and troubleshooting services for companies across Dubai and the UAE.

Frequently Asked Questions
Key questions regarding IP phone installation and configuration
What is included in your IP phone installation and configuration service?
Our service covers physical hardware assembly, PoE network verification, SIP registration, extension number and display name assignment, auto attendant/IVR integration, BLF key and speed dial mapping, voicemail setup, rigorous two-way call testing, and employee handover.
Can you configure our existing IP phones to work with a new or third-party IP PBX?
Yes. If your phones support standard open SIP protocols (such as Yealink, Grandstream, Fanvil, Cisco MPP, or Flyingvoice), we can factory reset, upgrade firmware, and reprogram them to register seamlessly with Yeastar, Grandstream UCM, 3CX, Asterisk, or cloud PBX platforms.
How do you fix one-way audio, echo, or phones showing offline?
We inspect the complete network and SIP transport route. One-way audio and registration drops usually result from router SIP ALG interference, NAT traversal conflicts, or blocked RTP port ranges. We configure Voice VLANs, router port rules, and STUN/keep-alive settings to permanently resolve these issues.
Can IP phones be configured for remote or home-office staff in the UAE?
Yes. Depending on your PBX architecture, we deploy secure remote extensions using encrypted SIP/TLS, built-in OpenVPN tunnels on the handset, or mobile/desktop softphone apps (such as Yeastar Linkus or Grandstream Wave), enabling remote staff to make and take company calls seamlessly.
Do you provide IP phone installation and troubleshooting outside Dubai?
Yes. Our field engineering teams deploy across all Emirates in the UAE, including Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah, and Umm Al Quwain, offering on-site installation, structured voice cabling audits, and immediate emergency troubleshooting.
