My gateway is configured in standard way (user side). config from 2651 below:
interface BRI1/1
no ip address
isdn switch-type basic-net3
isdn incoming-voice voice
isdn static-tei 0
voice-port 1/0/0
compand-type a-law
cptone PL
dial-peer voice 2 pots
huntstop
destination-pattern 618588...
progress_ind alert enable 8
direct-inward-dial
port 1/0/0
!
dial-peer voice 10 voip
destination-pattern 22.......
session target ipv4:x.x.x.x
The configuration DOESN'T change comparing to the running instalation with 3640
(IOS ver 12.2(5))
I think the problem is that in ios ver 12.2(11)T6 the ISDN SETUP message is
extended comparing to the 12.2(5) main line. And particulary I don't like this
long Facility string in ISDN SETUP message. In fact PBX doesn't see anything
after it in the SETUP message (no calling, no called number).
