Bonjour,
Je viens à vous car nous constatons en retour de notre support N1 de
plaintes émanant de clients indiquant des décalages dans la voix dans les
deux sens OVER IP; national, gsm, Intl quelques soit les PBX derrière.
Aucune jigue, aucunes pertes point à point => proxy vers OA; où
inversement; avec un minimum de sauts L3 (environ 30ms).
Liaison VOIP dédiée qui ne sature pas.
La problématique ne se pose pas lorsque l'on s'interconnecte en direct IP
d'IPBX à proxy.
Nous constatons ce phénomène uniquement sur des modèles OA T2.
Pas sur les OA100.
Opérateur alternatif nous ne générons pas d'horloge.
Nous utilisons la passerelle T2 / IP uniquement pour faire de la tolérance.
La partie modem n'est donc pas utilisée.
Tout renseignement est bon à prendre
Merci à vous tous et bonne semaine :)
