InterTel & Mitel - Maintenance & Support Services

Taking out an InterTel maintenance support contract with PSU will give you the peace of mind that both the labour and parts costs will be covered if anything goes wrong. We hold a significant stock of InterTel replacement parts distributed across the country to allow fast replacement in the unlikely event that you have a hardware failure. If an InterTel engineer has to attend site, they will usually have diagnosed what the problem is and make sure that they have any replacement InterTel parts onboard the van ensuring that your system is back up and running as quickly as possible.
