Dear list, After many unsuccessful tries with libss7, I tried with chan_ss7 and all my signalling links got up ss7srv*CLI> core show version Asterisk 1.6.2.10 built by root @ ss7srv on a i686 running Linux on 2012-03-21 11:17:53 UTC ss7srv*CLI> ss7 version chan_ss7 version 1.4.3 ss7srv*CLI> ss7 link status linkset siuc, link l1/16 INSERVICE, sls 0, total: 179, 16 linkset siuc, link l2/16 INSERVICE, sls 1, total: 276, 16 linkset siuc, link l3/16 INSERVICE, sls 2, total: 203, 16 linkset siuc, link l4/16 INSERVICE, sls 3, total: 247, 16 linkset siuc, link l6/16 INSERVICE, sls 4, total: 127, 16 linkset siuc, link l8/16 INSERVICE, sls 5, total: 166, 16 ss7srv*CLI> Kaloyan, special thanks to you. There was some issue with provider as well. They recreated DB at their end with 6 signalling links. And as you suggested I disabled all existing signalling links in both /etc/dahdi/system.con and /etc/asterisk/chan_dahdi.conf and enabled only last 2 signalling links. SS7 was up with libss7 using these 2 SLCs. Again I setup chan_dahdi.conf back with all 6 signalling links.

This is libss7 limitation even I recompiled it with libss7-1.0.2/ss7_internal.h:#define SS7_MAX_LINKS 16 asterisk-1.6.2.10/channels/chan_dahdi.c:#define NUM_DCHANS 16 Anyway, chan_ss7 worked now. If some one can suggest any update on libss7 I can give it a try.
