60 Conﬁguring CS 1000

Virtual Trunk route based on translations. The CDS answers

and reserves the Virtual Trunk in case it is needed to terminate

the incoming call.

The example shown uses an SPN and is deﬁned as follows:

Service DN = AC1 (from LD 86) + SPN (from LD 90)

For example, the value entered forthe Ser vice DN is 65100,

where 6 is Access Code 1 (AC1) (conﬁgured in LD 86 on "LD 86

Conﬁgure Access Code (AC1 or AC2)." (page 53)) and 5100

is the Special Number (SPN) (conﬁgured in LD 90 on "LD 90

Conﬁgure Service DN for Converged Desktop." (page 54)).

c. ConvergedTelephone Call Forward DN: This ﬁeld is required if

the SIP TrunkGateway application is enabled and the Converged

Desktop Service will be used. The Converged Telephone Call

ForwardDN is the CDN deﬁned in LD 23 for the CDS application.

This entry designates the CDN that CDS will acquire to obtain

messaging for call activity. CS 1000 telephones with CDMO

or CDMV Class of Service redirect all calls to the CDN. The

acquisition of the CDN identiﬁed in this ﬁeld allows messaging

for call activity to be processed to the CDS Application on the

Signaling Server.

For example, the value entered is 5100, which is the Control

DN (CDN) conﬁgured in LD 23 on "LD 23 Conﬁgure Control

Directory Number (CDN)." (page 52).

d. User Info. ﬁeld for Invite message on the Converged

Desktop MO Set: Verify the ﬁeld against the following string:

sip:convergeddesktop@SIPdomainname;nortelconverged=

continueforce

Ensure that the SIPdomainname is part of the string. The SIP

Domain name should have been conﬁgured during the SIP Trunk

Gateway conﬁguration.

If the string is missing the SIP Domain name (that is, the string

is sip:convergeddesktop@;nortelconverged=continueforce),

then the SIP Domain name was not conﬁgured during the SIP

TrunkGateway conﬁguration. The SIP Domain nameis found

under Signaling Server > Signaling Server xxx.xxx.xxx.xxx

Properties on the Edit web page (Figure 14 "Edit web page"

(page 58)).

This ﬁeld is used in the INVITE message of Converged Desktop

terminating call handling if the telephone is a multimedia-only

telephone.

e. User Info. ﬁeld for Invite message on the Converged

Desktop MV Set: Verify the ﬁeld against the following string:
