Frequently Asked Questions (Ongoing Telecom Support)
Practical answers to common queries regarding PBX installation, VoIP migration, and maintenance in UAE:
How quickly can your engineers deploy or troubleshoot an IP PBX system in Dubai or Abu Dhabi?
Standard installations are scheduled within 24 to 48 hours following a site assessment. For emergency technical faults or offline phone lines, our rapid dispatch team provides same-day on-site troubleshooting across Dubai, Sharjah, and Abu Dhabi.
Can we retain our current Etisalat or du landline numbers when upgrading to an IP PBX?
Yes. Our team seamlessly integrates your existing analog lines, ISDN PRI circuits, or SIP trunks directly into the new IP PBX through certified VoIP gateways, allowing you to keep all published numbers without service interruption.
Do you provide Annual Maintenance Contracts (AMC) for existing phone systems?
We offer comprehensive and non-comprehensive telecom AMC packages. These plans include scheduled quarterly system backups, automated security firmware updates, extension reconfiguration, and guaranteed response SLAs for unexpected outages.

Modern IP phone systems from Yeastar, Grandstream, and 3CX support mobile and desktop softphones. Your staff can place, receive, transfer, and record office calls through secure encrypted tunnels on laptops or smartphones from any location.
Is it possible to link multiple office branches in Dubai and Abu Dhabi into one centralized PBX?
Multiple physical locations can be linked via multisite IP networking. This setup enables free branch-to-branch calling via 3-digit extensions, unified receptionist call forwarding, and centralized IVR routing across all company locations.
