Hello,

I have v. strange problem with Cisco 1760 (IOS ver 12.3(7)XR).
The problem is connected with the look of called phone number comming
from PBX to Cisco (BRI interfaces).
Every dialed digit is doubled (in case of using OVERLAP dialing).
For instance if i dial 506047553 (on PBX side) i get 550066004477555533
which is then sent further through IP.
The situation is quite opposite if i use ENBLOCK (by pushing redirect
button).
Deriving from the logs below I am almost sure that PBX is sending the
digits properly thereby the problem is located somewhere in Cisco
configuration.

There is no translation rule set.


I've spent many hours struggling with this case, unfortunately without

Does anyone have any ideas what might be the problem?

Thank You,
