Passive hangup mode for callback triger

When you call UniBilling callback access phone number, it will not hangup actively. That is to say, it will wait the caller hangup the call. It will callback immediately after caller hangup. The benefit of passive callback is that the caller will always not miss the (legA) call.

Call route control

First, supports voicetrading like prefix billing. For example, prefix with 00 will go to silver route with normal rates. Without prefix00 will go to grey route with cheap rates. Second, could assign different routes for different resellers.

Minutes package

Subscribe a package will add 6000 minutes to your account (just an example). This means you can call all countries in the minutes package list for 30 days with at most 6000 minutes. When the 30 days are over, you will lost your credit.

DID call back without DTMF

Not all VOIP routes support DTMF. And those routes with (backward) DTMF supported usually much expensive than normal or grey ones. DTMF issue really big pain of normal DID call back.

UniBilling's new feature [Three points in one line] and [partial calling card] have solved this issue. The following shows how [[Three points in one line]] work.

Caller1 ---> DID1 ---> Caller1's Callee1

Caller2 ---> DID1 ---> Callee2's Callee1

You can see by the above simple logic UniBilling will be able to know callee phone number by caller and DID. So, DTMF is not needed any more.

As to [partial calling card], this way DTMF is needed but it is forward DTMF. Even worst VOIP grey routes support forward DTMF.

Just think it in a simple way:

1, You call DID number of UniBilling

2, You hear ringback tone

3, Input callee phone number

That is OK!

Press DTMF to hangup Callee

If UniBilling compiled with [continous call] option, no matter call back or calling card service could all continue to make next calls after callee hangup first. To avoid callee does not hangup first UniBilling added this feature to allow caller press a special DTMF such as * or ## to hangup callee and continue to make a next call.

Private DID call back

Not all of DID could guarantee to pass us correct callerid. To solve this issue, customer order a DID from unibilling and flag it as his [private DID call back access number]. If a call come to this DID, unibilling will know this is a call back request and it is trigered by this customer. Unbilling will then be able to process the legA of call back correctly.
