Known Affected Releases

8.6(2.24106.2) 9.1(2.11007.1) 9.1(2.11900.2)

Description (partial)

Symptom:SCCP devices supporting getPort opens a port with StationPortReq and a different port during OpenReceiveChannel as the confid and partyid pair sent from CUCM  is different in StationPortReq and OpenReceiveChannel. This could lead to orphaned streams at software device ( Conference Bridge, MOH, Annunciator, MTP ), leaked ports at hardware IOS devices (Conference bridge, MTP, Transcoder) leading to one way audio issues. Also If the Moh streams are stuck, any change in source id from admin page will not lead to new .wav files being played.

Conditions:It is a side effect of the fix CSCuj29943. 
 
This would be:
 
9.1.2.11007-1 and above
8.6.2.24106-2 and above
