QOS x VoIP su Cisco 887

Postby davide0522 » Wed 28 Mar , 2018 6:02 pm

Buongiorno. Ho questa configurazione su un cisco 887 VDSL e avrei bisogno di impostare un QOS per garantire un servizio di qualità sul voip.
Il cliente ha un pbx interno con ip 192.168.110.100 che connette il trunk sip verso un provider con ip 185.1.1.1 (ad esempio...)
Il problema è che hanno momenti della giornata in cui hanno molto scambio dati sia upload che download e in quei momenti la qualità della voce degrada.

Questa la configurazione installata. Qualcuno può aiutarmi a inserire un meccanismo di qos tale per cui nei momenti di saturazione venga ridotto il traffico in modo da consentire al 192.168.110.100 verso 185.1.1.1 di riservare un po' di banda ?

Grazie anticipatamente
