Hello Anders! Still cannot use chan_ss7 with over 8 e1s since chan_ss7 tries to access to /dev/zap/channel files and zaptel does not create over 256 (/dev system limitation i think) Could you please tell how did you succeed to use over 8E1 on your side since you have written that it supports over 8E1? I have over 8 signalling links in the single system and 8th is on the 9th E1.
