Business telephony configuration in Dubai

Make your PBX and SIP service work as one.

We configure 3CX, Yeastar, Grandstream, and Avaya systems with SBC and SIP trunk settings planned around your model, network, and provider requirements.

  • Compatibility and provider-specification review before changes
  • Call routing, voice-edge security, and media-path checks
  • Agreed cutover, test calls, and configuration handover

When voice breaks down

Small configuration gaps can disrupt every call

We trace the issue across the PBX, SBC, network, and provider handoff before changing settings.

01 / REGISTRATION

SIP trunk will not register

Authentication, peer definitions, address translation, or carrier parameters may not match the service profile.

02 / MEDIA

Calls connect with no audio

RTP paths, firewall rules, NAT, and advertised addresses can affect audio in one or both directions.

03 / ROUTING

Calls reach the wrong place

Dial plans, number formats, caller ID, and inbound rules need to agree across the PBX and SIP provider.

Configuration scope

One coordinated setup, from SIP profile to handover

We agree the work against your equipment and carrier documentation, then test the call paths your team relies on.

A

PBX and SIP trunk

Review platform version, trunks, extensions, dial plans, number format, and provider parameters.

B

SBC and voice edge

Configure supported signaling and media profiles, trusted peers, access controls, and firewall/NAT dependencies.

C

Quality and resilience

Check media reachability, QoS dependencies, failover behavior, and call paths within the approved design.

D

Inbound and outbound routes

Validate main numbers, direct inward dialing, caller presentation, hunt groups, and agreed destination logic.

E

Cutover and testing

Plan a maintenance window, test representative calls, and agree rollback steps before production changes.

F

Documentation and handover

Record settings, dependencies, test outcomes, and contacts so future support starts with the right context.

Platforms and compatibility

Support for the PBX you already use

We work with the platforms below. Exact compatibility depends on the installed model and software version, SBC, license, and SIP provider. We verify those details before recommending a configuration.

Frequently asked questions

Before you request an assessment

We did not find a public TDRA notice requiring every business PBX to use its own SBC. Ask your licensed telecom provider whether your specific SIP service has an SBC or interconnection requirement, and request its current written specification.
We work with 3CX, Yeastar, Grandstream, and Avaya environments. Support depends on the installed model, software version, licensing, SBC, and provider profile; we check compatibility before confirming scope.
Yes, subject to compatibility and access to the required configuration information. We review the provider's SIP parameters, existing call flows, and network path before planning changes.
Please share the PBX and SBC model/version, SIP provider, number of sites, the desired call flows, and a brief description of the change or issue. We may need a follow-up review before confirming a fixed scope.
No. SBC installation or configuration is not TDRA type approval. Applicable equipment approval and service requirements must be confirmed with TDRA and the licensed provider as relevant to your deployment.
Cost depends on the equipment, provider profile, number of call flows and sites, network work, and cutover requirements. We confirm the scope and provide a quote before starting.
