[asterisk-ss7] ss7 with ewsd

Mon Jul 6 04:33:18 CDT 2009

hi

i have problems with chan_ss7 to work with EWSD .
i have tried many configuration with and without crc4, with different
clock sources
without success, i always get NOT_ALIGNED message

i have also tried ss7 dump, but there wasn't any output

many thanks for any help, and sorry for my english ;)
