Hello I am a NOC operator of a high speed internet over satellite network, and I am currently testing pbxnsip over the satellite network. Typically our network runs around 650-800ms of latency, but in high use times I have seen it spike as high as 2000ms. At any rate I am extreemly pleased with pbxnsip in a low latency network, but I am having a few concerns with the satellite setup.
First off, over the satellite does work very well! I understand the latency will be effectively transfered in the voice timming. However what I would like to address is the amount of time it takes a call to initilize (go though). Once the call has established and has been on the go for a few seconds everything just levels out and works perfectly. But the odd time it takes 5-15sec from when the call is placed, to when the other phone rings, to when the person on the far side hears the initial "hello". This being said most people would have hung up the phone thinking the call has failed to connect. Is there some settings somewhere that I can optimize either right at the server or on the VoIP phones themselves to help this problem? If it requires some settings to the actual satellite network I can even investigate there. Any suggestions or thought I will gladly entertain.
- Our test server is a windows pc 2GHZ, 2GB Ram. And is located on an Internet IP - (with no router)
- Our phones are typically the Linksys SPA921/SPA922 or the ATA SPA2102
Currently we are still demo'ing pbxnsip and our key expires in approx 2 weeks. I would like to see about ironing out this long startup delay before then, so I can get the boss's approval to purchase pbxnsip asap.
Thanks for your help in advance.
