Delay when calling out on FXO

Hi Guys,


I have a voice gateway with an E1 card and two 4 port FXO ports. The system has been configured such that when one calls outside starting with a nine(9) the call is routed out throught the E1. When one dials with an 8 it passes through the FXO.


The main problem is that when I cal a number starting with an 8 it takes about 12 seconds for the call to connect. But when I call the same number with the 9 (E1) it connects almsot immediately. What could ve causing the delay?

Still no difference. On the E1 it connects automatically, but on the FXO there are still delays.
