In your log I see an "UNALLOCATED_NUMBER" release cause.
If the number is ok, this can be due to the ISDN numbering plan/number type of the called party.
What are required by your isdn provider?
You can try with different parameters (for your called number I think that you have to specify numbering plan=ISDN and number type=National).
These parameter can be specified in profile or dialplan.

Thanks John.

I could take a pcap trace using
wanpipemon -i w4g1 -pcap -pcap_file sng_isdn_fwd.pc -prot ISDN -full -systime -c trd

The q931 for a call which is not maturing is as follows. This is the case when the called number is set to unconditional forwarding.
3    6.057463    Local User    Remote Network    Q.931    SETUP
5    6.142822    Remote Network    Local User    Q.931    CALL PROCEEDING
7    Remote Network    Local User    Q.931    DISCONNECT
9    Local User    Remote Network    Q.931    RELEASE
11    Remote Network    Local User    Q.931    RELEASE COMPLETE

This happens only with Sangoma Card. I am using the sangoma_isdn stack and FreeTDM.  Somehow, it is not able to understand that the call is getting forwarded.

The q931 for a call which is maturing is as follows
11    Local User    Remote Network    Q.931    SETUP
13    Remote Network    Local User    Q.931    CALL PROCEEDING
15    Remote Network    Local User    Q.931    ALERTING
17    Remote Network    Local User    Q.931    CONNECT
23    Remote Network    Local User    Q.931    DISCONNECT
25    Local User    Remote Network    Q.931    RELEASE
27    Remote Network    Local User    Q.931    RELEASE COMPLETE

Anita,

You can use wireshark to decode the q.931 traces; the output files are
.pcap format.
