Dear All, Just an experience to run by all you experts out there. I have started to put more VOIP calls into Asterisk, most are pass-through calls and some are terminating on the Digium card to PSTN. Whenever I get to 10 calls or more, I would start to get choppy sound. I tried to ping other IP addresses from the Asterisk and noticed a big packet loss in the vincinity of 7% to 10%, but when there is no call, pinging the same IP addresses reap no packet loss. It seems that the VOIP packets are causing congestion of some kind on the LAN. I am using 100M, full duplex. I tried an autonegotiated switching hub as well as a more sophisticated managed switching hub and forcing the connection to be 100M Full Duplex, non negotiated. However, I reaped the same result.
Question is, do you know if it is better to use Managed switch and forcing the Ethernet connection to be 100M Full Duplex, or to use a normal UnManaged switch and let it negotiate. Also, I am using both a normal PCI LAN card as well as trying to use the onboard Intel 100PRO Lan card, and in both situations, I started to get lose packets when the number of calls increased. My colleagues, can anyone tell me if I am doing something wrong here, or is there something I am forgetting, or I simply need to use a more powerful LAN card due to the demand of VOIP packets. Waiting urgently for advice. Thanks Tom --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
