Notice that if you don't change Kamailio's basic config it will always RTP proxy for private IP addresses ( those specified on RFC-1918). If you are running your Kamailio server in a very low resource computer it can cause problems. To isolate where the problem is, I would recommend you disable the use of NAT and test your system using the same software client in both ends as most of the times this sound problem is related to software based codecs, CPU speed, bad wireless quality, etc. and this has nothing to do with your SIP registar.

Actually I've come far to this problem I have installed Kamailio as sip server/registrar and using default config. I have this situation: mobile cleint using IMSdroid (extension 100) windows client using Linphone (extension 300) Register satus: both clients register successfuly Both clients get connected to kamailio using my Wireless WIFI modem. I dial (from IMSdroid) to linphone: Both ring OK. Audio heard in IMSdroid is OK. Audio heard in windows linphone is just wind sound and jitter (or train sound, when I speak louder it gets louder) Video is ok in both sides (both clients show video clearly) Both clients get connected to kamailio (public internet IP) What the problem is from?
