Incoming SIP trunk calls
Call routing
The AastraLink Pro 160 automatically routes incoming SIP calls using the
TO:
address in the header of the SIP message. If the address matches a Direct Inward
Dialing (DID) rule and results in a valid SIP extension, the call is routed directly
to that extension. If no match is found, the call is sent to the current incoming call
destination (for example, open or closed hours routing to auto-attendant, operator,
or user group).
Calling party identification
The AastraLink Pro 160 SIP phones automatically display the calling party name
and number (CLID) when an incoming SIP call is received on a registered trunk,
using the
FROM:
address received in the header of the SIP message. The CLID is
also stored in the call detail records (CDR logs).
Outgoing SIP trunk calls
Call routing
The AastraLink Pro 160 default prefix for outbound SIP trunk calls is set to 8.
When Aastralink Pro users make a call, they dial the following:
(prefix digit) + (access digit) + (directory number)
Where:
prefix digit = 8
SIP trunk access digit = 0 - 9
directory number
For example, the number
82
9785551212 routes the outbound call over SIP trunk
#2 to directory number
9785551212.
For another example, the number
8
9783225434 routes the outbound call over a
single SIP trunk to directory number
9783225434
.
The AastraLink Pro 160 routes any calls with a matching SIP-trunk prefix and
trunk-accessor digit, to the appropriate SIP trunk. You can provision up to 10 SIP
trunks.
