Here is R3's debug dialer
R3#
01:42:44: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up
01:42:44: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to 8358662
01:42:44: BR0:1 DDR: disconnecting call
01:42:44: %LINK-3-UPDOWN: Interface BRI0:1, changed state to down
01:42:44: BR0:1 DDR: disconnecting call
01:42:46: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up
01:42:46: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to 8358662
01:42:46: BR0:1 DDR: disconnecting call
Somehow R3 is disconnecting a call according to the debug log
