Description (partial)


Making call from fax machine connected to ATA every time makes one leakage of internal subscription instance.
Since ATA187 allocates only 4 subscription instances, so outgoing problem appears when all instances are occupied.
This issue can be recovered when one more subscription time out.


The issue however does not occur with voice calls as the call flows are different.  In case of voice call, we are receiving CcAlertReq and the kpml was properly terminated with  SNFUnSubscribeReq. For the fax call, Linecontrol sent CcSetupRes , kpml was not being terminated in this case.
