Dear Saeed,
Could you please let me know the versions of asterisk and libss7 you're using?
As I don't have the necessary hardware to get it up and running, I am now
reading the source code of libss7 and chan_dahdi, I found that asterisk 1.6.0
is not compatible with the latest libss7 (rev. 267), but the libss7 maintainer
states that libss7 has been tested under asterisk 1.6.0.
the function prototype of ss7_add_link in libss7 rev.267 is as follows:
int ss7_add_link(struct ss7 *ss7, int transport, char *name, int slc,
unsigned int adjpc)
but asterisk 1.6.0 calls it as follows:
if (p.sigtype == DAHDI_SIG_MTP2)
ss7_add_link(link->ss7, SS7_TRANSPORT_DAHDIMTP2, link->fds[curfd]);
else
ss7_add_link(link->ss7, SS7_TRANSPORT_DAHDIDCHAN, link->fds[curfd]);
apparently, the number of parameters don't match, so I think libss7 Rev.267
will not compile with asterisk 1.6.0
Thanks ahead for you information and sorry for not being able to help you.
Best regards,
Tian

Subject: [asterisk-ss7] REL message with modified Redirection Number
Dear All
I am connected with my TDM switch with asterisk + libSS7 + DAHDI
My switch understand REL 23 as redirection cause.
My question is:
How can I put new modified number in Release message along with release 23?
If I simply do:
exten 600,1,Hangup(23)
Then debug of ss7 shows me Cause: Redirection to new destination (23)
-- Executing [...@default:1] Answer("DAHDI/31-1", "") in new stack
-- Executing [...@default:2] Hangup("DAHDI/31-1", "23") in new stack
== Spawn extension (default, 600, 2) exited non-zero on 'DAHDI/31-1'
-- Hungup 'DAHDI/31-1'
