Hi all, We are using - a dell sc440(Single dual-core intel xeon 3040, 1.86GHz,1066MHz front size bus 2MB cache) as the asterisk server - dell 400sc(Intel P4) as a SER server - digium isdn card, TE120P at Asterisk server - Bandwidth: 2Mbps/512kbps
All SIP Phones are registered to SER server, and SER will route all outgoing calls to Asterisk server. My problem is the sound quality goes down if more than 3 concurent calls to PSTN. Logically i think our system and bandwidth are more than enough to handle 3 concurent calls, but as the 4th person use it, the sound become jerky and a bit delay. So how can we improve the sound quality? Thanks Regards, jorain
