I understand your answer for why voicemail - as in it does not require realtime processing, but what about the echo back test? When I use echo back tests on other * servers or FWD I sound perfect - less some latency. Surely echo back is in realtime? Well - the echo app on the other side just sends back what it receives, frame by frame, as and when the frames turn up. So perhaps your end has sufficient jitter buffer to compensate, but the other end does not?

Voicemail is fine because it doesn't need realtime capacty - the voice frames arriving from your side go into the captured file as they arrive, doesn't matter if your 10 second message takes 20 seconds to arrive... You could try using a lower bandwidth codec like GSM if you aren't already.

Opps, at 3am I make stupid editing mistakes. Should read: I have a problem with jitter over a 2mb up 1mb down satellite connection. I call my friend over the satellite - **I can hear him perfect**, but he cannot make out a word I say. However if I leave him voicemail on his asterisk box, it records my voice perfect. I have this problem when calling other people as well. Storm D. J. Petersen mailto:[EMAIL PROTECTED] -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Storm D. J.

I call my friend over the satellite - I call perfect but they cannot make out a word I say. However if I leave him voicemail on his asterisk box, it records my voice perfect. I have this problem when calling other people as well. This is my setup: [my Grandstream]- [my * PBX]- [sat]- [friends * PBX]- [friends Supra Phone] (or any other device) I've also tried: [my Grandstream]- [sat]- [friends * PBX]- [friends Supra Phone] (or any other device) and: [my Grandstream]- [my * PBX]- [sat]- [friends Supra Phone] (or any other device) I've tried all combination of using SIP and IAX2 connections to bridge the calls using codecs ULAW and iLBC with all the same result. When I call my friends ECHO BACK TEST, I sound perfect (with a bit of latency). Anyone have some suggestions?

Hi there, this is just a me too... well, not exactly. I get jitter when trying to make SIP calls through Asterisk using a GPRS connection... can this be done actually? TIA, Martin Storm D. J.

RE: [Asterisk-Users] Jitter over Sat
I don't mind latency ... it's the garbage jitter where no one can understand a word. Interestingly enough if I do this it works fine: [grandstream 1]- [sat]- [pbx in mothers house] [grandstream 2]- [sat] -/ where the grandstream phones are side by side.
