I'm wondering how SLS is handled in libss7 and can it be manually defined as far as the default SLS value selection? I'm trying to get an SS7 link to synchronize with the PSTN. Physically, the link is good but it continues to swap between IDLE and NOTALIGNED. All cics are defined and correspond to the PSTN settings, as well as all the point codes. I did send an ss7 unblock linkset 1 command from the CLI just to see what happened with ss7 debugging turned on and noticed my Asterisk box was sending out SLS 9. The PSTN is using SLS 0 as default. Do the SLS values need to be aligned on each side, i.e. Asterisk box and PSTN? My current setup is the current versions of the following (just created the Asterisk box on Friday): Asterisk 10 dahdi-linux dahdi-tools libss7 libpri wanpipe (for Sangoma A104) I'm thinking I have an issue with the signaling link selection causing the misalignment. I can have the PSTN change settings, but would prefer to fix on my end if it is possible to declare the SLS default value somewhere. Thanks in advance! -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-ss7/attachments/20120305/d775ba30/attachment.htm>
