Hmm..unfortunately still no joy; something seems to have broken. With heads<br>of zaptel, libss7 and asterisk, I still get the following odd behaviour:<br><br>1) Upon startup, I get:<br><br><br>[Apr 12 16:02:37] ERROR[3300]: chan_zap.c:8566 ss7_linkset: Error in write
<br>Unknown error 500<br><br>repeated several times.<br><br>Shortly thereafter, I get:<br><br>chan_zap.c:8878 zt_ss7_error: [1] Received MSU in invalid state 0<br><br>..scrolling forever madly.<br><br>Asterisk chews 100% CPU.
<br><br>ss7 show linkset 1 shows SS7 up, but the other side shows the link going up<br>and down intermittently.<br><br>dmesg shows many lines of<br><br>HDLC Receiver overrun on channel TE4/0/1/1 (master=TE4/0/1/1)<br><br>
None of this happens when I set the signaling channel to a bearer timeslot,<br>for what it's worth.<br><br>Any ideas, please, anyone?<br><br>Regards,<br><br>Charl<br><br><br>> -----Original Message-----<br>> From:
