Téléphones industriels IP : impossibilité de maintenir ou de transférer des appels avec certains systèmes PBX

    Introduction

    Présentation

Les téléphones IP industriels haut de gamme tels que le X6U peuvent rencontrer des échecs de mise en attente ou de transfert d’appels sur certaines plateformes PBX. Ce problème survient car le X6U intègre la fonction vidéo dans son protocole SDP, or certains systèmes PBX ne prennent pas en charge la négociation vidéo pour ce modèle. Par conséquent, le PBX rejette la requête re-INVITE nécessaire à la mise en attente ou au transfert avec une réponse d’erreur 4xx ou 5xx.

    Modèles concernés

X6U/X210/X7C/X7/X7A/X3V/C600.

    Public visé

Ce document s’adresse au personnel de R&D interne, aux clients utilisant ces téléphones IP et aux équipes de test souhaitant résoudre les anomalies de mise en attente et de transfert sur les téléphones IP industriels avancés.

    Étapes de résolution

Désactivez la fonction vidéo du téléphone. Comme illustré ci-dessous, connectez-vous à l’interface web du terminal, accédez à Phone Settings--Function Settings et définissez le mode de réponse par défaut sur Audio.
