Hi all,
May be this question shouldn't ask hear. But I think you guys can give me a
clue. Because im fighting with this from long time.
My setup ;
I have a asterisk server + freepbx running on VPS where hosted with
burstnet. My partner send the call to this server thru sip trunk with g729
codec. Also i have another astersk now server located at my home. This home
located server connected to internet via ADSL link {dynamic IP} ( download =
2Mbps & upload = 512 Kbps). I connected this two servers using a sip trunk.
This sip trunk is connected via hamachi VPN. Home server have a 8port FXO
card which is connected to PSTN network.
My partners call come to vps server and then routed to home server and
terminate to pstn network.
Problem;
My problem is i cant maintain a qualiti call from my vps server to homer
server. Im using g729 licene codecs. Sometimes voice breaking. sometimes
sound is low. sometimes no issue. still im trying to figure out what is the
problem.
Normally maximum number of call at a time is 3.
I testest OPEN VPN and HAMACHI. What is the best VPN forVOIP ?
Testes codecs ; G729, g711, gsm What is suit for ADSL ?
Im doing testing testing and testing to achive good voice quality. Still im
failed.
Please tell me whats the best configuration to achive good sound quality
over ADSL link. I saw ILBC is good for ADSL than G729. Is it true ?
Im wondering skype works really fine when i use the same adsl link. But
sometimes one sip calls also not giving me good quality.
Please advice.
