Hi, I am trying to configure another asterisk box with some other PSTN switch. Link is showing up on asterisk but I am getting below on ss7 debug: WARNING[2150]: chan_dahdi.c:11509 ss7_linkset: MTP2 link down (SLC 0) MTP2 link up (SLC 0) Received out of sequence MSU w/ fsn of 1, lastfsnacked = 127, requesting retransmission WARNING[2150]: chan_dahdi.c:11509 ss7_linkset: MTP2 link down (SLC 0) MTP2 link up (SLC 0) Received out of sequence MSU w/ fsn of 2, lastfsnacked = 0, requesting retransmission MSU received, though still waiting for retransmission start. Dropping. Any idea what these warnings are related to ? Thanks, Deepika -------------- next part -------------- An HTML attachment was scrubbed...
