We have a PRI on one end using dialer profiles and a BRI on the other end
using legacy dialer maps. We have configured the BRI to request callback
but the PRI will not negotiate.
Here is part of the configs:
BRI
hostname R2-CHARLIE
username test-pri password 0 cisco
isdn switch-type basic-ni
isdn voice-call-failure 0
!
interface BRI0/0
ip address 192.168.182.27 255.255.255.0
no ip redirects
encapsulation ppp
dialer map ip 192.168.182.1 name test-pri 703xxxxxxx
dialer-group 1
isdn switch-type basic-ni
isdn spid1 703xxxxxxx0101 xxxxxxx
isdn spid2 703xxxxxxx0101 xxxxxxx
ppp callback request
ppp authentication chap
dialer-list 1 protocol ip permit
PRI
hostname test-pri
username R2-CHARLIE password 0 cisco
isdn switch-type primary-ni
interface Serial1/0:23
description ATT Local PRI Ckt 29-AHTZ-008043 LDN 703-234-2176 (2177)
no ip address

no ip directed-broadcast
no ip proxy-arp
encapsulation ppp

interface Dialer0
ip address 192.168.182.1 255.255.255.0
no ip redirects
no ip directed-broadcast
no ip proxy-arp
encapsulation ppp
dialer pool 1
dialer callback-secure
dialer string 703xxxxxxx
dialer caller 703xxxxxxx
dialer max-call 10
dialer-group 1
ppp callback accept
ppp authentication chap
ppp multilink
We haven't found a way to apply a map-class to the PRI end, although we
defined one:
map-class dialer callback
dialer callback-server username
Debug traces appear to show that the BRI is requesting callback but the PRI
is ignoring the request.
>From the BRI:
4d02h: BR0/0:1 PPP: Treating connection as a callout
4d02h: BR0/0:1 PPP: Phase is ESTABLISHING, Active Open

*Mar 3 05:33:04: Se1/0:0 LCP: O CONFREQ [Listen] id 21 len 30
We have to use dialer profiles, so going back to legacy ddr to make this
work is not an option. How do we get ppp callback to work successfully?
Thanks in advance!
