Incoming Routing Call Rule
Incoming Routing Call Rule means an incoming call which device was not registered to this
ePBX40 directly. However, the calling device was registered to an SIP Server or IP-PBX in
which ePBX40 was registered to. ePBX40 works as an Extension of SIP Server or IP-PBX at
this application. ePBX40 will perform the following behaviors based on the “Incoming
Routing” rule.
Suppose ePBX40 received an incoming call from SIP Trunk and its caller ID is 070070
which was registered to external SIP Server or IP-PBX directly. The Incoming Routing was
configured to Prefix=070070, Digits Length=6, Add=**999 and Drop=6.
ePBX40 will
drop 6 digits first and then add **999 as the destination number
. The **999 is the
default number of auto attendant. So the caller will hear greeting voice messages because
this call will be routed to ePBX40’s auto attendant.
Digits Length was used to compare the incoming call total digits length. If the incoming
call total digits length
DO NOT match Digits length number exactly
, this incoming call
will be neglected by this Incoming Routing table. ePBX40 continues to search other
number which match this incoming call number. If none of matched number, ePBX40 will
replies SIP command 403 (Forbidden) to the Calling device.
To change Incoming Routing, click
Configuration
, and then click the
Incoming Routing
table. The screen appears as follows.
Notice:
The
incoming call rule is used to look for the extension number that is
matched with the DNIS (Receiver side) which had been processed by digit manipulation.
If there is not any extension found, this call will be rejected.
