Abstract
The SIP Proxy issues a reverse DNS lookup for new inbound TCP and TLS connections to the SIP Proxy.
Download Description
PM45352 resolves the following problem:
ERROR DESCRIPTION:
The Session Initiation Protocol (SIP) Proxy is doing reverse
DNS lookups on new client connections even though security is
turned off
LOCAL FIX:
n/a
PROBLEM SUMMARY
USERS AFFECTED:
All users of IBM WebSphere Application
Server V7.0 and V8.0 Session Initiation
Protocol (SIP) Proxy.
PROBLEM DESCRIPTION:
The SIP Proxy issues a reverse DNS
lookup for new inbound TCP and TLS
connections to the SIP Proxy.
RECOMMENDATION:
None
The SIP Proxy issues a reverse DNS lookup for new inbound TCP
and TLS connections to the SIP Proxy. This can cause delays
processing messages.
PROBLEM CONCLUSION:
We removed the reverse DNS lookups at the SIP Proxy. To
enable this fix, you must add a custom property to the
SIP Proxy. In the administrative console, go to the
"WebSphere proxy servers > proxy > SIP proxy settings > Custom
properties page. Add a custom property with name
"disableAllHostNameLookups" and value "true".
The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.21 and 8.0.0.2. Please refer to the
Recommended Updates page for delivery information:
