What an IP phone deployment covers

Eight workstreams that turn an empty office into a working call experience.

A phone system is more than handsets. We design the dial plan, port your numbers, configure call recording, integrate with your CRM, and verify call quality before sign-off.

IP-PBX deployment

Microsoft Teams Phone, 3CX, Yealink, Cisco, or your preferred platform. Cloud-hosted or on-prem. Designed around your call patterns, not a generic template.

Carrier integration

Etisalat or DU SIP trunks, number porting, fibre delivery coordinated with the carrier. We handle the bureaucracy so your team does not lose a week on hold.

Number porting

Existing 04, 056, or 800 numbers ported to the new system, typically inside one business week. Continuity through the cutover, no number changes for your customers.

IVR & call routing

Auto-attendant, call queues, ring groups, time-of-day routing, holiday schedules, voicemail-to-email. Designed around your team structure and customer experience.

Soft-phone & mobile

Microsoft Teams, 3CX app, or your preferred soft-phone, configured for desk, mobile, and laptop. Same number rings everywhere, mobile-first deployments fully supported.

Microsoft 365 integration

Direct Routing or Operator Connect for Teams Phone. Calls integrated with Outlook, Teams meetings, presence, voicemail. Single identity, single device, single experience.

CRM integration

Click-to-dial, screen pop, call logging into Salesforce, HubSpot, Zoho, Bitrix, Dynamics. Inbound caller-ID lookup, outbound call attribution, recording linked to records.

Call recording & analytics

Selective or full call recording with consent prompts, retention policies, and search. Wallboard, agent stats, queue reports for sales and support teams.

Why GR IT for telephony

Four reasons clients pick us for the phone system.

Phone systems are easy to install poorly and hard to install well. Here is what makes us good at it.

100+ deployments

Pattern recognition matters. We have ported numbers across Etisalat and DU, integrated with every major CRM, and tuned call quality on Dubai links.

Platform-agnostic

Microsoft Teams Phone, 3CX, Cisco, Yealink, Asterisk-based systems. We pick the platform that fits your call profile, not the one we resell.

Carrier relationships

Direct working relationships with Etisalat and DU enterprise teams. Faster trunk provisioning, faster number porting, escalation paths when needed.

Dubai-based engineers

On-site for installation, reachable for ongoing support. The team that designs your dial plan is the team that takes the support call when it stops working.

Industries we cover

Phone-system profiles by sector.

Six common shapes. Call volume, recording requirements, and integration vary, the discipline does not.

SME offices

10-50 staff offices, single trunk, simple IVR, mix of desk and mobile soft-phones. Most common profile and where Microsoft Teams Phone often fits.

Retail & multi-location

Multiple stores, central HQ, customer-facing 800 number with smart routing to the nearest store, recording for quality monitoring.

Professional services

Law firms, accountancies, consultancies. Privacy-aware recording with retention rules, conference bridges, voicemail confidentiality.

Healthcare clinics

Appointment lines, patient confidentiality, integration with patient-management software. Triage queues, call-back automation for high-volume periods.

Schools

Reception lines, parent communications, broadcast announcements, classroom phones. Holiday schedules and emergency-line routing handled out of the box.

Sales-led businesses

Outbound sales, inbound qualification, CRM-integrated dialling. Wallboards, agent stats, call recording for coaching, click-to-dial for productivity.

How a deployment runs

From discovery to go-live.

Every deployment runs the same path. Documented, evidenced, deliverable on a fixed timeline.
  1. 1

    Discovery

    1 week

    Site visit, headcount, call patterns, current system audit. Output: dial-plan design, platform recommendation, written SOW.

  2. 2

    Trunk & port

    1-3 weeks

    Etisalat or DU SIP trunk provisioning, number porting initiated. We coordinate the carrier paperwork and chase the timeline.

  3. 3

    Build

    1-3 weeks

    Platform configured, IVR built, CRM integration wired, hardware shipped. End-to-end test calls before any user touches it.

  4. 4

    Cutover & support

    Day-1 + 2 weeks

    Numbers ported, old system retired, new system live. Engineer on-site for the first day. Support tickets close as users hit issues, not next week.

“We had a Cisco PBX from 2015 that needed a forklift upgrade. GR IT designed a Microsoft Teams Phone deployment with Direct Routing through DU, ported 60 numbers in five business days, and integrated with our HubSpot CRM. Our remote sales team finally has the same phone capabilities as the office, and our PSTN costs dropped by a third.”

Common questions

IP telephone (VoIP), frequently asked.

Depends on your other tools. Microsoft 365 customers usually find Teams Phone the simplest fit because identity, soft-phone, and meetings are unified. CRM-heavy sales teams often pick 3CX for richer call routing. Contact centres need a dedicated CCaaS platform. We will recommend based on your specifics, not push the one we resell.

Etisalat and DU number ports typically complete in 5-10 business days from paperwork submission, depending on carrier workload. We pre-stage everything so the cutover is the port date itself; no service interruption beyond a brief switchover window.

Yes for offices with proper internet connectivity and a configured QoS policy. We assess your circuit before deployment, recommend dedicated voice VLANs and switch QoS where needed, and run pre-cutover voice quality tests. Our deployments hit MOS scores above 4.0 by default.

Most modern SIP handsets (Yealink, Cisco SPA, Polycom VVX, Grandstream) work with most platforms. Older proprietary handsets (Cisco SCCP, Avaya, Mitel) usually need replacement. We assess hardware compatibility during discovery and tell you what works as-is.

Customer-facing recording requires consent prompts under UAE consumer protection guidance. PCI DSS recording (for card-on-call) needs additional controls. Healthcare and legal recording have retention rules. We design the recording policy during discovery and document the compliance posture.

Soft-phone apps on iOS and Android. Same number rings everywhere; calls move between devices mid-conversation. Outbound calls show the office number on caller-ID, not the personal mobile. Mobile-first deployments are common; full desk-phone replacement is uncommon now.

Yes for the major platforms: Salesforce, HubSpot, Zoho, Microsoft Dynamics, Bitrix24, Pipedrive, Odoo, Freshsales. Click-to-dial, screen pop, and call logging at minimum; richer integration (recording links, analytics) varies by platform. We will scope the integration depth in the SOW.

Three failover options: secondary internet circuit (most common), 4G/5G failover router for the SIP trunk, or carrier-side call forwarding to mobiles during an outage. We design failover during deployment so a circuit failure does not silence your business.
