I have a 3640 Gateway with E1 interface connected to a PBX (isdn switch-type primary-net5 protocol) in one site and 3640 Gateway with analog FXO interface in another site.
When the ISDN Gateway send call to the analog Gateway, it receive Q931 connect message in any case :
- when the phone is busy in the analog GW site
- when the dial number is wrong in the analog GW site
- when the phone is ringing in the analog GW site and no answer
Some one has any idea to rectify the problem ?
Thanks for any answer
