Caller ID on ISDN

Hi,

I have a central router that multiple customers dial into for access to
my network, I have a central PRI and I have legacy DDR with dialer maps
on a dialer interface for each customer, however I am setting up a new
customer and they are using caller id (I currently do not) and when i
try to connect to them my call is being rejected, is there any config
that I'm meant to apply on my end for my call to be accepted?

My config is :

interface Serial1/0:15
no ip address
encapsulation ppp
dialer rotary-group 1
isdn switch-type primary-net5
no cdp enable
!
interface Dialer1
ip address 1.1.1.1 255.255.255.0
encapsulation ppp
no keepalive
dialer in-band
dialer idle-timeout 60
dialer fast-idle 15
dialer map ip 1.1.1.2 name customer1 4110908
dialer map ip 1.1.1.6 name customer2 016056187
dialer map ip 1.1.1.8 name customer3 00441344884418
dialer map ip 1.1.1.10 name customer4 4072958
dialer map ip 1.1.1.12 name customer5 6387900
dialer-group 1
no cdp enable
ppp authentication chap
ppp chap hostname xxx
ppp chap password xxx
ppp multilink

Thanks in advance

1) It is probably not a good idea to post phone numbers to your data network
on the usenet.

2) I see some are international calls. Is the failing location
iternational? Your callerID info may not match the dial out number
especially if they have dial 9 or dial 0 to get an outside line.

3) Do they need to dial 9 or dial 0 to reach you?

Check debug isdn q931 on their side, and see what caller ID looks like, and
if it matches the dialout number.

If not, they need to use a map of the form

dialer map ip name (callerid info) (full phone # with prefixes)

eg

dialer map ip name 4085551212 00014085551212

on **THEIR** side.

As long as you send callerid info, it is not your problem.
