We have been limited in two choices for free DID: ipkall and Sipgate.
Both have problems. Ipkall cannot do SIP register, 30-day removal, no
CID with GV, unreliable DTFM and call quality sucks. Sipgate does not
offer SIP forwarding and, to put salt on the cut, it is not reliable
when registered with SipSorcery and free SS account allows only one
SIP provider. It stopped giving out DID long ago. Calls suffer from
significant delay.
Now CallCentric offers free DID and it is perfect: in addition to SIP
register like Sipgate, you can also, like ipkall, SIP forward to, say,
username@sipsorcery.com. Of course, you can add the DID to GoogleVoice. I
have made some GV calls via SS and quality is perfect without
noticeable delay.
Even more exciting: it supports CID with name! If no name tighten to
the DID, it'll show the city and state. This feature is disabled by
default, so you need to enable it.
When you register a free CC account, make sure you say "Not in USA",
or your account will be forced to pay 911 fee for any DID including
this free one.
The phone numbers have area codes for NY area. It does not matter, because we only use such a # for GV. If you need a local #, GV is there.
大师，有设置步骤么？
ReplyDelete这个DID本身很简单，申请一个免费的account，然后加上一到多个DID。
Delete怎么用这些DID，那就不是一两句能说清除的了，有简单的用法，也有非常复杂的。在手机上用的最简单的用法是：
下载和安装Acrobits 1.94 + G.729，添加一个SIP account，用户名是1777xxxxxxx，domain是callcentric.com，启用stun.counterpath.com， 把G.729码推到最上面。
屏幕左上方出现的电话图标由红变黄，再变成绿色，就成了。找个电话打这个DID，Acrobits应当响铃。如果声音不好，注意上面说的一点要把G.729放到第一位。如果没有声音，注意上面说的一定要启用stun。这样接电话就好了，完全免费的。
如果把这个号码加到GoogleVoice里，那么别人打你的GV号码的时候，Acrobits也会响铃。
然后下载和安装CrowdCall，把这个DID给它，拨一个美国或中国的号码，然后Acrobits会响铃，接听，按照提示按1。Bingo，完全免费打美国和世界许多国家！
CrowdCall现在不好用了，可以改用Voice+ (Google Voice callback) by Szilárd Kovács。
Delete请教前辈高人，我仔细的按照你的步骤注册了Callcentric, 安装了Acrobits1.94+ G.729, 一路绿灯，测试拨出电话也很顺利，正窃喜我这个电脑盲沿高人指引方向也能成功，结果悲剧了，打入的电话没有反应，总收到提示音 unavailable, GV没法验证添加，前辈指条明路吧，问题在哪里呢？
ReplyDeleteAcrobits是直接注册到CallCentric？如果是，DID Forwarding选默认的SIP Device。然后在CC的Dashboard上确认”Your phone is registered“。如果是”Your phone is not registered“那就接不了电话。
Delete是啊，都是这样的，打出可以，打入就不行，所以觉得很郁闷，不知道问题在哪儿。。。。 还请高人前辈指点，多谢多谢
ReplyDelete因为Sandy飓风，这些天CC的号码不工作。
Delete原来这样啊，我以为武功秘籍传到我这里失灵了，哈哈，谢谢您，搞了我一天， 啥时候好啊
ReplyDelete不知道。噢八马说连任后先去打篮球，罗母泥说他的第一件事是把中国列为货币操纵国。搞不好要等到下次选举。
Delete哈哈哈，谢谢，看到它页面上的公告了， 有啥别的替代品么？
