[cisco-voip] Caller ID name display on AS5350, part deux

[Adam Rothschild]

So, I've got a AS5350 running 12.4(1)a, which seems to have added the
capability to interpret calling party name (which was absent from 12.3
mainline, and present but unusable due to other functionality broken
in 12.3T, I might add).

Configuration is thus:

interface Serial3/0:23
 no ip address
 load-interval 30
 isdn switch-type primary-ni
 isdn incoming-voice modem
 isdn supp-service name calling
 isdn negotiate-bchan
 isdn outgoing display-ie
 no cdp enable
[...]
sip-ua 
 disable-early-media 180
 retry invite 3
 retry response 3
 retry bye 3
 retry cancel 3
 sip-server ipv4:10.10.10.10
[...]
dial-peer voice 2 pots
 incoming called-number 2015551212
 direct-inward-dial
!
dial-peer voice 102 voip
 destination-pattern 2015551212
 session protocol sipv2
 session target ipv4:10.10.10.10
 codec g711ulaw

Call comes in, 'term mon ; debug isdn q931' sees the full ISDN
facility codes, including the calling party name.  However, the
10.10.10.10 SIP peer does not see the caller ID name or a RPID header
on the message coming in, just the calling party number in the From
header.

Clues?

Thanks in advance,
