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 829785551212 routes the outbound call over SIP trunk #2 to directory number 9785551212.

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.

Calling party identification

By default, the AastraLink Pro 160 sets the calling party name and number (CLID) in the FROM: address of the SIP trunk call, using the extension number of the phone which originated the call. In cases where the SIP trunk service provider does not accept arbitrary CLID, AastraLink allows a static CLID to be provisioned instead; setting the "Caller ID" field on the SIP trunk configuration overrides the per-call CLID and uses this value for all outgoing calls placed to the SIP trunk.
