Passing names between Nortel and Cisco is somewhat tricky as the default
definition of Cisco is to pass them in Q.931 fields while Nortel expects them
over Q.sig fields. With the help of Cisco support here is what is needed to
tell the Cisco gateway to send/receive them via Q.sig:

isdn switch-type primary-qsig (so it will use Q.sig signalling).

...

voice service voip
qsig decode (This sends names out via Q.sig)
fax protocol pass-through g711alaw
sip

....

controller E1 0/0/0
pri-group timeslots 1-31

...

interface Serial0/0/0:15 (This is for E1 PRI).
no ip address
encapsulation hdlc
isdn switch-type primary-qsig
isdn overlap-receiving
isdn not-end-to-end 64
isdn incoming-voice voice
isdn supp-service name calling (This receives names via Q.sig)
isdn negotiate-bchan
isdn outgoing ie facility
isdn outgoing ie caller-number
isdn outgoing ie called-number
no cdp enable
