FAQ
Passive hangup mode for callback
triger
When you call SetuBilling 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
You can assign different quality with different calling
prefix. 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.
SetuBilling'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 SetuBilling 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 SetuBilling
2, You hear ringback tone
3, Input callee phone number
That is OK!
Press DTMF to hangup Callee
If SetuBilling 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 SetuBilling added this feature to
allow caller press a special DTMF such as * or ## to hangup
callee and continue to make a next call.
Register or TopUP account with
SMS
For a new account, send the following sms to gsm modem will
be able to bound callerid with this new account:
Account # Password
or
Account # Password # CallerID
For a already bounded callerid, send the following sms to
gsm modem will be able to recharge his account balance with
new account:
Account # Password # CallerID
Private DID call back
Not all of DID could guarantee to pass us correct callerid.
To solve this issue, customer order a DID from SetuBilling
and flag it as his [private DID call back access number].
If a call come to this DID, SetuBilling will know this is
a call back request and it is trigered by this customer.
Setubilling will then be able to process the legA of call
back correctly.
