I have been working with Cisco for several weeks trying to get an 804 ISDN
router to do dual channel DOV to a PM3 with CT1's. The first channel works
just fine, but the second channel will not connect. A 'debug isdn events' on
the Cisco seems to show it trying to connect:
00:58:50: ISDN BR0: Outgoing call id = 0x8035, dsl 0
00:58:214748364800: ISDN BR0: Event: Call to 5551111 at 56 Kb/s
00:58:214748365483: ISDN BR0: process_bri_call(): call id 0x8035, number
5551111
, speed 56, call type VOICE
00:58:50: ISDN BR0: received HOST_DISCONNECT_ACK call_id 0x4FFF98
00:59:85899345920: ISDN BR0: Event: Hangup call to call id 0x8035 ces = 1
00:59:85904656708: ISDN BR0: process_disconnect(): call id 0x8035, call type
is
VOICE, b_idb 0x2696F38, ces 1
00:59:20: CC: dsl 0 No CCB Src->HOST cid 0x8035, ev 0x5 ces 1
00:59:20: ISDN BR0: received HOST_QUERY_RESPONSE call_id 0x8035
The Cisco is configured to do DOV and appears to be doing so in the debug
above. I tested with a 3COM and an Ascend box on the same BRI and both were
able to connect dual channel using DOV. I also dialed into a different
access number that uses PRI and I was able to do dual channel 64K.
I know this is probably more of a Cisco issue, but I have tried there first
and have so far been unsuccessful. Does anyone know what is going on here?
Also, there are a number of ISDN debugging commands on the PM3, but how do I
debug with a CT1?
