Description (partial)

"Stop Routing Q.931 Disconnect Cause does" Service Parameter does not take place or effect SIP Trunkwith Multi IPs


SIP Trunk1
SIP Trunk2

if they assigned to RG and the first Trunk got a call disconnected with casue 38 
whilst the Stop Routing on Q.931 Disconnect Cause Code  CONFIGURED with this disconnect cause,
the call gets REALLY stopped being re-routed as expected. which GOOD!


if we have ONLY ONE SIP Trunk configured with 2 IPs 
and we got the disconnect with 38, 
the CM is Re-routing to the second IP listed at the trunk whilst the Service PArameter config does not take effect!
