Hello list, i have two E1 running on a asterisk 1.8 with chan_ss7 which i have set to production state last week. And after around 5000 calls i can see that 3 channels are in state BLOCKED Remote Maintenance. My carrier said he hasnt blocked anything on this two E1 lines but he can see some messages even on busy lines he doesnt understand. Asterisk was automatically restarted every night but these three channels stay at this state. Is this a known bug or what can i do to solve this problem? asterisk verison 1.8 (Asterisk SVN-schmidts-unleash-the-beast-r343849) chan_ss7 version (chan_ss7 version 2.1.0) but with some patches to isup for connected line information and also the patch for the additional calling party header. thanks! best regards stefan schmidt
