RTPManager.addTarget() - takes few sec (2-3)

Question

Hi all,
I use AVTransmit2 as base for my test. When call is answered at CTI port I call
AV2Transmit.start().
It takes 2-3 second to open session.
(RTPManager.addTarget() )
If I call AV2Transmit.stop() and after it AV2Transmit.start() again, it starts streaming imediately.
What takes so long and how to avoid these delays?
Cisco phone, Call manager and PC are in the same subnet.

Here is a solution to addTarget() problem I first posted on JMF forum on Nov 4, 2005
http://forum.java.sun.com/thread.jspa?threadID=247408
This is a quote from my post:
To resolve addTarget delay problem do this trick for the first target:
String ipadr = [target ip address];
int port=[target port];
InetAddress adr = InetAddress.getByName(ipadr);
byte[] badr = adr.getAddress();
InetAddress nadr = InetAddress.getByAddress( InetAddress.getLocalHost().getHostName(), badr );
[Or even simpler: InetAddress nadr = InetAddress.getByAddress( “localhost”, badr );]
Now addTarget (new SessionAddress(nadr, port)) takes no time at all.
Again it's enough to do this only for the first target.
