Hi, I have Asterisk 1.4.0 using Queue App. I use PRI connecting my Asterisk with Siemens EWSD This was working OK but since two days I have this error: [Jun 22 10:53:09] WARNING[8050] chan_zap.c: Ring requested on channel 0/3 already in use on span 1. Hanging up owner. [Jun 22 10:53:09] WARNING[8050] chan_zap.c: Ring requested on channel 0/3 already in use on span 1. Hanging up owner. [Jun 22 10:53:14] WARNING[8050] chan_zap.c: Ring requested on channel 0/3 already in use on span 1. Hanging up owner. [Jun 22 10:53:15] WARNING[8050] chan_zap.c: Ring requested on channel 0/3 already in use on span 1. Hanging up owner. [Jun 22 10:53:15] WARNING[8050] chan_zap.c: Ring requested on channel 0/3 already in use on span 1. Hanging up owner. I the EWSD try to send a call in this channel I hear a busy tone. In the others channels asterisk answer ok. And when it happends only restarting Asterisk I can fix the error, it happends two times a day.
