Billing problem for a call forwarded by the extension of one of our customers

7. Troubleshooting Troubleshooting
1

One of our customers faces a Billing issue.
I will try to explain clearly:

External caller number: 0637218903 (A)
Customer device number: 0179355068 (B)
Forwarded number: 0757009639 (C)

Call Scenario:
A calls B which forwarded (Do not disturb) to C

Inbound call:
( C ← B ← PBX ← SBC ← IP Directions ← (External caller number A)

Outbound Call:
PBX (B/C) → SBC → Jaguar Network → External caller number A)

Billing issue at Jaguar level:
We see in From header the Initial caller number (A) instead of B
In fact, B is never billed even though he has made a forwarding and therefore initiated a call to C

Customer Request:
The customer wants A’s number displayed on C’s phone but B billed instead A number

1st Question:
Do you have a solution that will display the number of the initial caller on the final telephone but that we still bill the number of the PBX customer?

2nd Question:
Going on this point below

for Outbound Call:
PBX (B/C) → SBC → Jaguar Network → External caller number A)

If PBX doesn’t include the Diversion header in his INVITE message, how SBC can generate information about Redirecting number and OriginalCalledNumber in the CDR?

*1st Question:

We do have CDR fields that you can add:

@{RedirectingNumber}:

@{OriginalCalledNumber}

From,
Text Call Detail Records - TBwiki (telcobridges.com)

Call detail record - TBwiki (telcobridges.com)

So, if you could include this field in the CDR format, it will be available from CDR records which you can utilize to bill correctly.

Mainly the RedirectingNumber should be the B number in your case.

*2nd Question:
Going on this point below

for Outbound Call:
PBX (B/C) → SBC → Jaguar Network → External caller number A)

If PBX doesn’t include the Diversion header in his INVITE message, how SBC can generate information about Redirecting number and OriginalCalledNumber in the CDR?

Here, for outbound, do you mean, B is forwarded to C, then? how the call is called out to outbound and to A?

If no diversion header, we may not see it. We currently also are not supporting History-Info at the moment…
