回复: 关于VOIP,我知道的点点滴滴
建议在SIP里设置一下Stun Server,即可实现UDP对NAT的简单穿越。我把Freephoneline带回国使用,原来也是只能单向的,设置了Stun Server后,就解决了问题。以下是一些常用的免费的Stun Server:
stun.ekiga.net (alias for stun01.sipphone.com)
stun.ideasip.com (no XOR_MAPPED_ADDRESS support)
stun01.sipphone.com
stun.softjoys.com (no DNS SRV record) (no XOR_MAPPED_ADDRESS support)
stun.voipbuster.com (no DNS SRV record) (no XOR_MAPPED_ADDRESS support)
stun.voxgratia.org (no DNS SRV record) (no XOR_MAPPED_ADDRESS support)
stun.xten.com
stunserver.org see their usage policy
stun.sipgate.net:10000
numb.viagenie.ca (http://numb.viagenie.ca) (XOR_MAPPED_ADDRESS only with rfc3489bis magic number in transaction ID)
stun.ipshka.com inside UA-IX zone russsian explanation at http://www.ipshka.com/main/help/hlp_stun.php
请教一下LZ,拿回国用的VOIP,开始用的还不错,现在是ONE WAY CONVERSATION,有没有可能是国内的ISP做了什么手脚?用的是SPA2102.
