Problem call from Asterisk 1.4 to ISDN

Hello,

I have a cisco router 2901 configured as VoIP gateway, to route calls from an Asterisk PBX to a Primary trunk E1.

I have been working with an Asterisk 11 without problems. But now I'm testing the same scenario with an Asterisk 1.4 and I'm getting problems calling to cellular phones.

The dial-peers I have defined are:

dial-peer voice 2 voip
description outbound calls from Asterisk (inbound leg)
session protocol sipv2
incoming called-number .
voice-class codec 1 
dtmf-relay rtp-nte
no vad
!
dial-peer voice 4 pots
description outbound calls from Asterisk (outbound leg)
destination-pattern .
no digit-strip
port 0/0/0:15
!

I attach the trace (SIP and q.931 deb) Comparing with other traces, I can see some things suspicious:

1) The 100 SIP trying message is sent to Asterisk before than the SETUP message has been sent to the ISDN network

2) This message appears after ALERTING:

Progress Ind i = 0x8282 - Destination address is non-ISDN

3) After the ALERTING, a CONNECT message arrives from ISDN network (but the user didn't answer the call, in fact no alerting arrives to the cellular phone and no lost call neither)

Jan 14 12:40:20.735: ISDN Se0/0/0:15 Q931: RX <- CONNECT pd = 8  callref = 0x80EB
    Progress Ind i = 0x8282 - Destination address is non-ISDN 
    Date/Time i = 0x0E010E0D2816
        Date (dd-mm-yr)   = 14-01-14
        Time (hr:mnt:sec) = 13:40:22
    Connected Number i = 0x00C3

4)The time in the previous message is wrong (Asterisk and Cisco has the clock 12:40 one hour before)

5)After the CONNECT message, a DISCONNECT message arrives from ISDN

Jan 14 12:40:24.527: ISDN Se0/0/0:15 Q931: RX <- DISCONNECT pd = 8  callref = 0x80EB
    Cause i = 0x829F00000000 - Normal, unspecified
    Progress Ind i = 0x8288 - In-band info or appropriate now available
Jan 14 12:40:24.527: %ISDN-6-DISCONNECT: Interface Serial0/0/0:9  disconnected from XXXXX , call lasted 3 seconds

Any idea?

Problem call from Asterisk 1.4 to ISDN

David,

From the look of this, it looks like the ISDN is playing a message before audio is connected..

   Progress Ind i = 0x8288 - In-band info or appropriate now available

Usually, you need PRACK to cut through audio on the sip leg...Can you post the full debugs both sip and ISDN?
