Omer,
I think you are trying to configure something in a non supported way.
(and BTW, you are missing interesting traffic in this example)
Legacy DDR is configured via config in the interface AND dialer map.
Profiles are configured via pools(or group)+dialer interface and dialer
string.
The router needs to match the destination ip to the connection somehow.
This is done via dialer map in legacy (name or calling number), and via
name to dialer interface matching in profiles.
If you don't provide the relation, it does not work.
01:02:23: BR0/0:1 MCB: Initialize
01:02:23: BR0/0:1 DDR: Authenticated host R2 with no matching dialer map
01:02:23: BR0/0:1 DDR: Can't start callback to R2
01:02:23: BR0/0:1 DDR: disconnecting call
