hey bro you did a grat job. at least your trick works :-).
Problemis to find out ss7 spec on the internet is very troublesome. Most of them you may need to buy.
Your addon can be used with the people who are working with ANSI variant of SS7 :-)

Hi
There seems to have no keywork ?variant? in chan_dahdi.conf and not even in the source code.
If you are talking about ?ss7type? keywork, it is already set to ANSI
I don?t know if we are using the standard on libss7 or if the carrier is using a different standard but
not all Network Management Messages (SNM) are not working.
I checked the code source and change in libss7 the following and it seems to make it work.
In mtp3.c, in the function net_mng_send,
case NET_MNG_LIA:
case NET_MNG_LUA:
case NET_MNG_LID:
case NET_MNG_LLT:
case NET_MNG_LRT:
/* RUDDY ADDON */
layer4[0] = (unsigned char) (param & 0xff);
layer4[1] = (unsigned char) ((param >> 8) & 0xff);
ss7_msg_userpart_len(m, rllen + 1 + 1);
/* RUDDY ADDON */
//ss7_msg_userpart_len(m, rllen + 1); /* no more params */
break;
So, basicly, when send those message, we send two extra bits as requested.
I?m not sure that this follows any SS7 specs but it did the trick.

if you are using chan_ss7, put the keyword
variant and its value to ANSI
look for the same thing if you are using DAHDI and libss7
it should work.

I don?t think so.
Do you now where I can find specs of SS7 ANSI (T1 111, 112 and 113) ??
And where we should fix it ?

Can you ask your operator to use ITU-WHITE instead of ANSI? I think that will solve the problem.

Hi all
We had a SS7 link with our provider here in Canada. Everything went well.
But they are saying that asterisk is missing the SLC parameter when sending messages like LUN or LUA etc..
So, this make asterisk not compatible with the SS7 protocol. In the debug message they send us from their switch,
You can see that asterisk is always sending a SLS parameter as SLC.
Do you know how we can fix it ??
