First, thanks a lot for the guys at Sifira for the work on chan_ss7. We, at ss7.pl wrote some patches for chan_ss7, to make life with it a bit easier ;) Here's what you get: manhattan*CLI> help ss7 [...] ss7 send grs Reset link circuits ss7 show links Show linksets and link names ss7 show uptime Show linksets uptime [...] Those new commands work like this: manhattan*CLI> ss7 show uptime Linkset test restarted at Thu Nov 2 10:31:03 2006 Uptime on linkset test is 1 minute 55 seconds manhattan*CLI> ss7 show links Number of linksets: 1. Linkset 1 name is: test. Number of links in linkset: 2. Link number 1 name is: l1 Link number 2 name is: l2 manhattan*CLI> ss7 send grs l1 Nov 2 10:33:07 NOTICE[3556]: l4isup.c:3858 cmd_send_grs: Sending GROUP RESET messages on link 'l1'. Note, the 'ss7 send grs' command works diffrent from the 'ss7 reset' command from stock chan_ss7 - it resets the circuits on a single span, not all of them at once. You can find the patch here: http://www.ss7.pl/~jacke/patches/chan_ss7/chan_ss7-0.9.patch.gz To apply it to your copy of chan_ss7, move all the files from a stock chan_ss7 to a directory called 'chan_ss7', move the patch file to higner level directory, and run the following command: patch < chan_ss7-0.9.patch After that, proceed like you did before with the clean copy of chan_ss7. If you have any questions - drop us a note.
