1 year warranty — free repair in Morocco if it breaks down during the warranty period

1 year manufacturer's warranty

This product is covered for 1 year by a manufacturer's warranty (the brand's official warranty). Your iris.ma invoice serves as the warranty document: keep it safe.

A problem with your product? Don't worry: contact us by phone, WhatsApp or e-mail. Depending on the brand, we direct you either straight to the repairer appointed by the brand to fix your product, or to us — and we take care of the rest.

  • If a repair is possible, it is carried out free of charge.
  • If the product cannot be repaired, the brand offers an exchange for another product.
  • If no product is available, a refund is issued as soon as the brand confirms it.

Faulty straight out of the box? Some brands offer an immediate exchange, others a repair. Contact us to find out what applies to your product.

The warranty covers breakdowns occurring under normal use, as defined by the brand's terms. Product breakage (drop, impact, liquid…) is not covered, nor are certain consumable parts.

New, never opened — our commitment

All our products are new, delivered in their sealed original packaging.

We commit to never sending you a product that has been opened, unboxed or returned by another customer — even one “just opened for checking”.

Any doubt on delivery (damaged box, seal already opened)? Point it out to the courier or contact us immediately: we take the product back and send you another one.

Sales invoice

Every order comes with its sales invoice, included with the parcel (handed over in person for a store collection).

Ordering for a company? Using the details you give at checkout (company name and ICE), the invoice is issued in your company's name, with its ICE.

Frequently asked questions about this product

What is the difference between the Grandstream UCM6308A and UCM6304A?
Capacity and the number of analogue ports: 1,500 users, 200 concurrent calls and 8 FXS + 8 FXO ports here, versus 1,000 users, 150 calls and 4+4 on the UCM6304A. Two sizes within the same range.
How many conferences can the Grandstream UCM6308A host?
9 audio conference rooms, with up to 150 participants in total. They are hosted by the phone system itself: no external platform or monthly subscription is involved.
What are the 8 FXO ports on the Grandstream UCM6308A for?
For connecting eight analogue telephone lines from the carrier. The 8 FXS ports, for their part, power existing analogue devices — fax machines, lift phones, intercoms — which you keep without replacing them.
Does the Grandstream UCM6308A power phones via PoE?
Yes, it has 3 PoE+ ports at 10/100/1000 Mbps and a built-in NAT router. Three phones can therefore be powered directly by the phone system, without an additional PoE switch.
Does the Grandstream UCM6308A handle video?
It is presented as ideal for audio-only environments. This is the point to settle before buying: this model is aimed at telephony, and the range includes other models for video use.
Where can the Grandstream UCM6308A phone system be installed?
In a 19-inch rack or on a desk: mounting is flexible and quick. It also has a USB 3.0 port and an SD card slot for recordings and backups.
Is the Grandstream UCM6308A phone system new and under warranty?
New, reference UCM6308A, in original Grandstream packaging. The invoice serves as the warranty document for 1 year. Keep it: it is the document that will be requested if you make a claim.
