Úgy néz ki mostanában csak Voice-al kell foglalkoznom. Sajnos ez a terület elég új nekem de már a CCVP slide-jait nézegetem:)  A mai feladat az volt, hogy egy Cisco 2851-es router SIP hívásokat fogadjon, és 4 darab E1-es trönkön küldje tovább azokat egy Avaya alközpontnak. Ez 120 hívást jelent, és g729 esetén 240 DSP-re van szükség. A router-ben 3 DSP slot van ami 120 híváshoz kevés lenne, ezért egy NM modult is kellett használni, melyen további 4 slot van.

A konfig (nem teljes, de a lényeges részeket kiemeltem):

Belefutottam egy érdekes Voice problémába. Egy Cisco 2811-es routerrel kellett megoldani DTMF-Relay funkciót. A mobil szolgáltató rtp-nte-n küldi a DTMF jelzéseket, viszont inband DTMF-ként kell tovább küldeni azokat. Ezt a következő konfiggal tudtam megcsinálni (nem valós IP címeket, és telefon számot tartalmaz) :

Nincs időm leírni hogy ez hogy működik, nézzetek utánna a referenciában szereplő linkeken.
