What codecs are you using? I have noticed that g729, for some reason, adds a lot of latency to the phone. Running on uLaw, however, I get times from sip show peers of around 5-14ms.

Do you have any problems when there are a low number of concurrent calls? Do you ever get any messages saying the phones are unreachable? Or lagged? What kind of Internet connection do you have? Do you have any problems with calls between phones on the same network (no routers in between)? What model of switches do you have?

Yes, from what I've seen and tested, it doesn't make a difference how many calls there are. Do you ever get any messages saying the phones are unreachable? Or lagged? Yes, a phone not being used often enough will often report 'UNREACHABLE' When a call is made that changes What kind of Internet connection do you have? We have a synchronous T1 connection. The phones run on the same network as data. Do you have any problems with calls between phones on the same network (no routers in between)? There are some static issues but nothing like outside calling were the person being called drops off for 10 seconds at a time. Switches used are 3com Baselines 2024 What model of Internet router do you have? Cisco 1700 router My main concern is the fact that the soft-phone is reporting only 4ms of delay and the cisco phones are reporting 200. All the time, regardless of network bandwidth. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [Asterisk-Users] Snom high SIP ping time
If you ping on the SIP port the message has to go through the application layer - which takes some time considering it is an embedded system with a small CPU. That part should be ok. It the phone becomes choppy, that problem is probably related to the RTP side. Maybe you have different packet sizes for incoming and outgoing traffic. You can get an Ethereal trace from the web interface of the phone which should show you the RTP jitter (PCAP trace). Or use a hub if you don't trust that trace. 6.1 is the latest version if you want to try the latest image (http://www.snom.com/wiki/index.php/Beta_Firmware).
