Hi Kaloyan,
If I change ss7type=ansi the link doens't work:
[Jul 26 11:05:43] ERROR[637]: chan_dahdi.c:13836 dahdi_ss7_error: [3] Received message destined for point code 0x37c372 but we're 0x372. Dropping
The ERICSSON uses ITU standard as well. It uses ITU/ISUP BRAZIL.
But the Ericsson doesn't understand the F on the number.
Hi Jakub,

I talked with the Ericsson admin and this SWITCH uses the length of the dialed number to determine the end of the number. It doesn't accept the F simbol.
Actually, ERICSSON has route for 13 digits. My libss7 is sending 14 digits (0151136001000F) and because this, the ERICSSON are rejecting the call.
Unfortunately my telco says that I need to take off this F signal.
Is there any way to do this?
thank you very much.

Hi,
make sure your switchtype is properly configured.
ITU requires the number to be terminated with '#' which is 0xF
ANSI does not want/like the '#', so probably you have 'ss7type=itu' while
the other end is ANSI
