Hello,
Centos 6.9, Asterisk 14.6.
I have one sip provider called “TEL”. When smb calls, after hangup CLI says:
ERROR: channel.c:1181 __ast_queue_frame: Unable to write to alert pipe on SIP/tel-00000000 (qlen = 0): Permission denied!
What does it mean? Can someone know what is a reason?
Thank You,
Michal
