Hi all,<br><br>I have setup a Dell PowerEdge 2550 with a Sangoma A200 card with 2xFSO and 1XFS modules.<br><br>The PowerEdge specs are 1 x P3 1133MHz, 512MB RAM.<br>Sangoma A200 has 3 analogue PSTN lines connected.<br><br>
This server is based in Office 1, with 5 users all with a Linksys SPA942 VoIP Handset.<br><br>There is another Office (Office 2) connected to here using VPN. There are two users in Office 2 with the Linksys SPA942 VoIP Handsets, they are connected also over VPN to the remote Trixbox.<br>
<br>When placing calls from either Office 1 or Office 2 calls are fine, there is echo to start with (Echo training) but then it clears. Volume is ok, quality is ok.<br><br>However when an incoming call is made to the office the quality is pretty bad, crackles, low volume.<br>
<br>There has also been mention (In office 1) of some cross talk.<br><br><br>The Trixbox is plugged into the master switch in the server room, where the various production servers are running, and all workstations are also connected directly to the switch.<br>
<br>Is there any reason why I should be experiencing such bad line quality on inbound calls from PSTN? Call quality is perfect when plugging in a regular analogue phone. I am in the process of having all the VoIP handsets in Office 1 connected directly to its own switch, and then connected to the Trixbox directly to avoid server/workstation bandwidth issues, but I don't think would solve the quality issues. Is the PowerEdge powerful enough to handle the VoIP traffic. I am really at an end with this, and really need to find a solution.<br>
<br>Any help, advice or pointers would be greatly welcomed.<br><br>Thanks,<br><br>PaulG.<br><br><br>
