Outbound calls from our UC520 work fine via a single BRI interface. However when I make incoming calls I get number unobtainable. I have logged a fault with BT and they say the line is fine. I have a single BRI interface in the ALL_BRI trunk group.
I have tried to configure a direct dial on the DID number to call the auto attendant or a hunt group. Neither works.
Does anyone have any tips on where to look next?

I would look at the isdn debug output to see what's being passed by BT as the DNIS. We will need to make sure that we map the correct DNIS to AA/Opertor, etc.
Can you capture the ISDN debugs and also post your current config?
Thanks,

Which ISDN debugging will show what I need:
ar_ucs_sibc_01#debug isdn ?
all ISDN debug messages
api ISDN Application Program Interface(s)
cc ISDN Call Control
error ISDN error messages
events ISDN events
mgmnt ISDN management
q921 ISDN Q921 frames
q931 ISDN Q931 packets
standard Standard ISDN debugging messages
tgrm ISDN TGRM events
ar_ucs_sibc_01#

debug ISDN q931 should show you what you need.

Here is the output I get when I try to dial the number:
ISDN BR0/3/0 Q931: RX <- SETUP pd = 8 callref = 0x01
Sending Complete
Bearer Capability i = 0x9090A3
Standard = CCITT
Transfer Capability = 3.1kHz Audio
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0x89
Exclusive, B1
Progress Ind i = 0x8581 - Call not end-to-end ISDN, may have in-band info
Called Party Number i = 0x81, '782628'
Plan:ISDN, Type:Unknown
ISDN BR0/3/0 Q931: TX -> CALL_PROC pd = 8 callref = 0x81
Channel ID i = 0x89
Exclusive, B1
ISDN BR0/3/0 Q931: TX -> DISCONNECT pd = 8 callref = 0x81
Cause i = 0x8081 - Unallocated/unassigned number
ISDN BR0/3/0 Q931: RX <- RELEASE pd = 8 callref = 0x01
ISDN BR0/3/0 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x81

BT is presenting 6 digits, as it should. The problem is you are expecting all digits (including STD). So you need to change the following
1. Dial Peer 3010 nees to have:
incoming called-number 01932782628
changed to:
incoming called-number 782628
2. Change your translaion rule:
voice translation-rule 8
rule 1 /01932782628/ /501/
to
voice translation-rule 8
rule 1 /782628/ /501/
That should work

Yes, that worked! Many thanks for your help.

Want to clarify that all the troubleshooting and configuration for this setup could have been done through CCA :)
Did you use CCA to make the config changes?
