Cloud or on-premises phone system: what to choose for a business in Morocco

The short answer: a cloud phone system suits most service SMBs, whose teams are mobile, remote or spread across several sites, and whose numbers come in over a SIP trunk. An on-premises phone system, in the form of an IP PBX appliance, remains the best choice when you must keep analogue lines or GSM SIM cards, when reception must keep working whatever happens to the internet, or when the site has door phones, DECT handsets and local equipment. In between, the hybrid model, a cloud PBX with an on-site gateway, solves many mixed cases. This guide gives you the criteria to decide, and the concrete options from 3CX, Yeastar and Grandstream.

At ALLSAFE SOLUTIONS, we are a 3CX Bronze partner, Advanced certified, a Yeastar certified partner and a Grandstream integrator in Casablanca. We deploy both architectures, and we supply licences and hardware, with or without installation. The capacities quoted here come from the vendors’ websites; we do not give prices, which vary by edition, distributor and period.

If you are new to the subject, start with our guide to business IP phone systems in Morocco, which covers the basics. This article goes further on the single question of where the system runs.

Cloud, on-premises, hybrid: what exactly are we talking about?

“Cloud” actually covers several situations, which need separating before any comparison:

Architecture	Where the PBX runs	Who maintains it	Examples
Vendor-hosted cloud	The vendor’s infrastructure	The vendor for the platform, you or your provider for the configuration	3CX hosted by 3CX, Yeastar Cloud Edition hosted by Yeastar, Grandstream CloudUCM
Private cloud	Virtual machine at a cloud provider or hosting company	Your provider	3CX in your own cloud, Yeastar Cloud Edition or Software on your infrastructure
On-premises	Appliance or server in your comms room	You or your provider	Yeastar P520 to P570, Grandstream UCM6300, 3CX on a local server
Hybrid	PBX in the cloud, gateway on your premises	Your provider	3CX or Yeastar Cloud with an FXO or GSM gateway on site

In every case, the core features are similar: auto attendant, call queues, recording, mobile apps, integrations. The real difference lies in five points: how your lines come in, what happens when the internet goes down, who handles maintenance, where the data sits, and which specific features exist on only one side.

The options from 3CX, Yeastar and Grandstream

Vendor	Cloud	On-premises	Worth knowing
3CX	Hosted by 3CX, or in your own cloud; free SMB edition hosted by 3CX for up to 10 users	Server or virtual machine on your premises	Same software everywhere: you can change hosting without changing tools. See which 3CX licence to choose
Yeastar P-Series	Cloud Edition, hosted by Yeastar or on your infrastructure, from the Enterprise plan	P520, P550, P560, P570 appliances, with FXO, FXS and 4G modules	Hot Standby and hotel (PMS) integration not available on Cloud Edition. See which Yeastar model to choose
Grandstream	CloudUCM, hosted by Grandstream, with capacity depending on the chosen plan	UCM6300 and UCM6300 Audio, from 0 to 8 FXO ports	Automatic phone provisioning, built-in meetings. See which UCM to choose

Sources: 3CX, Yeastar and Grandstream websites. The free 3CX SMB edition suits a very small organisation; as soon as you need a structured reception, advanced queues or CRM integration, you move to a commercial edition.

The six criteria that actually decide

1. How your lines come in

This is the first criterion, and often the most decisive. If your numbers come in over a SIP trunk, the PBX can be anywhere: cloud is the natural fit. If you keep analogue lines, an E1 circuit or GSM SIM cards for calls to mobiles, you need physical equipment on your premises to connect them.

With an on-premises appliance, these lines plug directly into the PBX’s FXO ports or GSM modules. With a cloud PBX, you add a local gateway that converts them to SIP. We cover this equipment in FXO, FXS and E1 gateways and GSM and 4G gateways. And to move gradually to a SIP trunk without changing numbers, see SIP trunk: keep your numbers.

2. The quality of your internet access

With a cloud PBX, every call from desk phones goes over the internet, including calls between two colleagues in the same office. The link must therefore be stable, with consistent latency, and protected by quality of service on the router or firewall. With an on-premises appliance, internal calls and calls over local lines do not depend on the internet. See business fibre: choosing and securing your link.

3. Business continuity

The two architectures do not fail in the same way:

Incident	Cloud PBX	On-premises PBX
Internet outage at the office	Desk phones cut off; the PBX keeps running and can forward to mobiles or another site	Internal calls continue; external calls continue on analogue or GSM lines, stop on a SIP trunk
Power cut at the office	The PBX stays reachable, mobiles take over	Everything stops without a UPS, including reception
PBX failure	Handled by the host	Down until replaced, unless a second appliance runs in high availability
Office inaccessible	Teams answer from home with nothing to change	Remote access must be planned in advance

Cloud protects better against incidents that hit the office; on-premises protects better against an internet outage, if the lines are local. Either way, a second internet link and a UPS on network equipment make all the difference.

4. Remote work and multiple sites

The cloud is built for this: every site, remote worker and mobile app connects directly to the PBX. On-premises can do it too, but you need the vendor’s remote access service, such as Remote Access at Yeastar or RemoteConnect at Grandstream, or a VPN. What you must never do: open the PBX interface to the internet with port forwarding.

5. Maintenance and updates

In a vendor-hosted cloud, the platform is updated and backed up for you; configuration, phones and network still need administering. On-premises, everything falls to you or your provider: firmware updates, configuration backups stored off the appliance, monitoring, hardware replacement. An appliance that is never updated becomes an entry point for toll fraud.

6. Data and specific features

Recordings, voicemails and call logs contain personal data, governed by Law 09-08. On-premises, they stay in your building; in the cloud, they sit with the host, and you need to know where and for how long. Also check the features you need: at Yeastar, for example, hotel software integration and high availability are not offered on Cloud Edition.

Our decision grid

Your situation	Our recommendation
Service SMB, mobile or remote teams, numbers on a SIP trunk	Cloud: hosted 3CX or Yeastar Cloud Edition
Several branches, no local lines to keep	Cloud, one PBX for every site
Very small organisation, a handful of users	3CX SMB hosted by 3CX, or CloudUCM
Single site with analogue lines, fax, door phone, alarm	On-premises: Yeastar P-Series or Grandstream UCM
Heavy use of GSM SIM cards to call mobiles	On-premises with a GSM module, or hybrid with a GSM gateway
Hotel, clinic, industrial site, reception that must never stop	On-premises with high availability, or cloud with dual internet links
Multichannel contact centre, advanced CRM integration	3CX, preferably hosted. See 3CX call centre
Transition: current lines kept for a while, SIP trunk to come	Hybrid: cloud PBX and local gateway, removed when the time comes

The hybrid model, often the right compromise

Many businesses in Morocco are in a mixed situation: some numbers on a SIP trunk, a few legacy analogue lines, SIM cards for calls to mobiles, and staff on the move. The hybrid model puts the PBX in the cloud, for mobility and continuity, and installs a small gateway on site to connect the local lines.

Its advantages: one PBX for everyone, mobile apps that work everywhere, and a gradual exit from analogue lines without changing tools. Its limit: if the office loses internet, the local lines are no longer connected to the PBX. Hence, once again, the importance of a second link.

The mistakes we fix most often

1. A cloud PBX on an internet link without quality of service, shared with backups and downloads: choppy audio at peak times.
2. An on-premises appliance without a UPS, when it is what keeps reception running.
3. A cloud PBX chosen when all lines are analogue, then a gateway added in a hurry.
4. The admin interface exposed to the internet, whether the PBX is in the cloud or on site.
5. No fallback plan: no automatic forwarding to mobiles, no second link.
6. SIP ALG left on in the router, a classic cause of one-way or silent calls, see the mistakes that ruin call quality.
7. Choosing on the advertised monthly fee without comparing the full cost: licences, hardware, gateways, maintenance, lines. See IP phone system budget.

Checklist before choosing

• List of lines to keep: analogue, E1, SIM cards, and numbers to port to a SIP trunk.
• Peak concurrent calls, and number of users.
• Share of remote workers and number of sites.
• State of the internet link, whether a second link exists, quality of service on the firewall.
• UPS on the network and, where relevant, on the PBX.
• Local equipment: door phones, alarms, fax, DECT handsets.
• Requirements for recordings and call data.
• Must-have features: contact centre, CRM, hotel software, high availability.
• Who handles maintenance and monitoring.
