Cisco Unified SIP Proxy DNS SRV based call routing does not work after 

rebooting Cisco Unified SIP Proxy.

There are two workarounds. The first is to toggle off, then on the sip 

dns-srv command. The second is to configure route tables with server-group based 
routing.

When trying to make a call to the SRV defined device, Cisco Unified SIP 

Proxy cannot establish a connection and issues a 502 message to the calling device.

This problem only occurs if the network is of type NAT.

Use a different network type, standard, for example.

The maddr parameter in the request-uri is not handled properly.

Cisco Unified SIP Proxy fails to remove the maddr parameter if it is 

pointing to Cisco Unified SIP Proxy on incoming requests. Cisco Unified SIP Proxy 
fails to forward the message based on the maddr address on outgoing requests.

Normalization on user portion of request-uri fails, NullPointerException is 

thrown during normalization operation. (This can be seen by looking at the trace.log
