Roaming Agreement had been effected, a situation which is denied by
ETKL. In the circumstance, it is surprising that ETKL has not taken the
reasonable step of querying the genesis of the bill with AREDU;
h) That if indeed there was a valid roaming bill to ETKL in respect of
unauthorized roaming calls, this points to high level fraudulent activity;
i) The suspected practice of call-back scenario as presented by ETKL is not
technically feasible and raises more questions than answers. The
Commission has carefully analyzed the suspected scenario and finds it
necessary to bring out its interrogation of this aspect as shown in italics here
below :
a) B party (Say 0751xxxxxx) calls access number +254 751362050
( ACL number issued by ETKL in Kenya)
b) ACL Initiates call-back through internet to an ISP provider in
Dubai – A Call back means the calling number (B-party-0751xxxxxx) is
called back from Dubai and the number to call back will be a Dubai number
(not ETKL number to generate a roaming TAP file)
c) The call is dropped but Dubai gets all call details & calls back
through DU GSM Network (local call) When the call is dropped, the B
number details will be known to the Dubai ISP for call back and a call back
will be initiated to B party (0751xxxxxx) by a Dubai number. How then
will the same B-party (0751xxxxxx) appear to be calling from Dubai when
it is supposed to be called back in Kenya?
d) This call generates a TAP file payable by ETKL. (How can a number
being called back in Kenya generate a TAP (roaming) file, when it is
supposed to be called back while in Kenya? How possible is it that a Kenyan
number will call a GSM network through an SS7 link of an ISP in Dubai?
e) Through the internet, the call gets terminated in ACL Kenya
f) ACL Kenya delivers the call to ETKL through E1 connection (If
this is the case, did ETKL bill ACL for any calls delivered through the E1
link? The Commission was informed that ACL does not get any bill from
ETKL as per the current arrangement. The link provided is bidirectional but
ACL only uses one direction of calls coming from ETKL to ACL through
the E1 link.
