The pilot point number is 32000 belongs to receptionist. Receptionist have extension number 32001,32002,32003,32004 & 32006 . We have ccm version 4.1(3)sr5d with publisher and subscriber in the iptel environment. The receptionist phone is registered to the subscriber . We tried to call the pilot point number 32000 from extension number 32255 (mac address 0011BBA02052 ) and other extension number but end up with "engaged tone" . Hereby attached the pilot point, hunt group and cm trace for both pub and sub. You can refer to 28 april sub.rar --> sub sdi --> ccm00000247.txt . You can trace from ccm00000247.txt . The calling session is between 16:50 - 16:58 . From extension number 32255 ( mac address 0011BBA02052) --> pilot number 32000 . Please advise how to solve this issue? We hope could call 32000 .Your effort shall be highly appreciated.
