Dear All, I am testing one of your E1 cards "D110P" with chan_ss7. When I connected 2 cards back to back they worked perfectly and I forwarded some calls from one asterisk box to the other. When I connected them to our ss7 provider. I get some errors in asterisk logs. Here is sample of these errors: Jul 19 13:04:13 NOTICE[3267] mtp.c: MTP changeover last_ack=4, last_sent=4, from schannel 1, no INSERVICE schannel found Jul 19 13:04:13 NOTICE[3267] mtp.c: Failover not possible, no other signalling link and no other host available.

When I added crc4 to the zaptel configuration the ISUP and MTP messages stopped on the link and no log entries I am not sure about the E1 / T1 Jumper. I do not have easy physical access to the server so I used the following command to override the jumper settings insmod /lib/modules/2.6.9-34.0.2.EL/extra/wcte11xp.ko t1e1override=15 Do I have to change it physically to avoid any confusion ? I have attached a pcap capture of the traffic on the wire. I am currently using chan_ss7. Should I test with libss7 the native ss7 implementation ?
