Unity UM 'unidentified caller' problem between Unity servers

Team,
We are simulating a clients UM setup using Unity 4.0(5) befor we migrate everything to Unity 7.0(2) and CUCM 7.1(3).
We setup 2 Unity servers in different locations in one AD domain. Each location also has its own Exchange 2003 servers which the Unity servers are pointing to as its message store. We are also integrating with one CCM cluster 4.1(3). VMO is also enabled on users Outlook.
Sending voicemail messages between users within the Unity servers works fine. Users are able to see the sendees name on the email message and Live reply is functioning.
However, sending voicemail messages accross Unity servers have some issues. Users are seeing the messages as coming from the Unity server itself and not from the user who sent it. The email header would like this:
     From:      Unity Messaging System - [server-name]
     To:          [user-name]
     Subject:     Message from an unidentified caller ([caller-extn-number])
The media message would play just fine. But live reply is not possible.
Using the Call Viewer, the number being displayed are correct while the call is in progress.
Did some checking using CUDLE and both Unity servers have all the subscribers extensions on DTMFAccessID table and on the GlobalSubscriber table all the users from both Unity are there.
Anybody from the forum have encountered this before?
Appreciate it if somebody can share some thoughts on how to solve this problem.
Thanks and kind regards,
Neil

Have you configured digital networking between the 2 Unity systems? To me, what you are describing makes sense. You have 2 separate systems. Unity knows about items that belong or are associated to it (i.e., your intra-system communication works as desired). But, it does not know about information (other than calling info) related to the separate system. My first suggestion would be to read up on digital networking - doesn't require any additional licensing as it's Unity to Unity...in other words, VPIM isn't a concern here.

Problems with subscriber search between unity servers in a dialing domain

I have two Unity 8 Active/Passive clusters in the following configuration Site A    Unity Cluster A    Exchange Server A Site B   Unity Cluster B   Exchange Server B The Exchange servers are on the same Active Directory Domain and in the same MS Exchange OrganizationThe unity clusters are on the same domain as the Exchange Servers and are connected to the same Cisco Call manager 7 system. The unity clusters are in a Dilaling Domain that should allow them to share subscriber information. Everything seems to be configured correctly but for some reason when I do search for all subscribers on Cluster A i can't see the subscribers on Cluster B and vise versa. As a result the auto attendant on cluster A can't transfer calls to subscribers on cluster B. I've gone over every document I can find and no matter what i do i can't seem to solve the problem. Can anyone point me in the right direction to solve this problem. Any help would be greatly appreciated.

Hi Gyasi,
Firstly, please ensure you go through every step of the Cisco.com document on "Digital Networking" for Unity 8.0.   There are various different things that need to be configured; such as ensuring each of the Primary Unity servers, for each location, have had each of their Primary Location set to use the same Dialing Domain.
Does the GlobalSubscriber table, in SQL, include all of the users from the other cluster?   This will at least indicate whether or not Unity has been successful in synch'ing back all users from it's local Active Directory Domain Controller (DC).   If the DC's weren't communicating correctly, then this type of issue could easily occur.
Kind regards,
Craig

NFS problem between RedHat Client and Solaris Server

Hi all, we are experiencing a problem between a RedHat client and a Solaris 10 server. For the purposes of this post, I'll call the Redhat client server A and the Solaris 10 server B.
Server B is exporting a filesystem that server A is trying to mount. Server A can successfully mount the exported file system, however, strange things are happening. If I change to the exported mount point on server A and create a file, the file is owned by nobody:nobody, not the user that created the file.
A look at the file on server B shows the file has the correct UID and GID (ie the UID & GID of server A).
The fstab file on server A looks like this:
serverB:/data /data nfs4 rsize=32768,wsize=32768,hard,nointr,rw,bg,actimeo=0,timeo=300,suid 0 0
Does anyone have a explanation for this?
NB: There is a firewall between server A and server B. A firewall rule is in place to allow traffic between the two servers on port 2049
Stewart

Hi
If I change to the exported mount point on server A and create a file, the file is owned by nobody:nobody, not the user that created the file.On a NFS share, for security reasons, you normally dont have root provileges.
A file createt as root user will be mapped to nobody:nobody.
The behaviour you see is correct.
If you want the file to be createt as root, you have to export the filesystem with -o ro,anon=0
NFSv3 will be blocked by your firewall.

Problem between SOAP Sender and JDBC Receiver

Hi,
I have a asynchronous scenary between SOAP Sender and JDBC Receiver.
The idea is sending an ID for updating one register.
Table structure is:
TABLE AS_PERSONA
    (P_RUT                         VARCHAR2(10) NOT NULL,
    P_NOMBRE                       VARCHAR2(50),
    P_APELLIDO                     VARCHAR2(50))
The ID is the P_RUT field.
The structure of message that I send by SOAP, is the following:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
     <SOAP-ENV:Body>
          <m:MT_CONS_SOAP xmlns:m="urn:prueba:voliva">
               <CONSULTA>
                    <P_RUT>15445</P_RUT>
               </CONSULTA>
          </m:MT_CONS_SOAP>
     </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The JDBC receiver structure is:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_CONS_PERSONA xmlns:ns0="urn:prueba:voliva">
     <Statement>
          <AS_PERSONA action="UPDATE">
               <table>AS_PERSONA</table>
               <access>
                    <P_NOMBRE>DELETE_BY_XI</P_NOMBRE>
                    <P_APELLIDO>DELETE_BY_XI</P_APELLIDO>
               </access>
               <key>
                    <P_RUT>15445</P_RUT>
               </key>
          </AS_PERSONA>
     </Statement>
</ns0:MT_CONS_PERSONA>
When I do a call to SOAP by XMLspy, it returns a message without data, that means succesfull reply.
I see message monitor and see the succesfull flag. But in the database it doesn't update the register.
This scenario was proved using the File Sender and same JDBC Receiver, then result was succesfull.
I proved SOAP Sender with a File Receiver, storing information from SOAP sender in an archive, and works well.
Then I imagine that exist some problem between SOAP and JDBC. what could be happening ?
Thanks.

Hi,
Looks like the problem is with the JDBC receiver...try updating the value in the table by using a File-JDBC scenario..does it work..check the adapter monitor in RWB..

Jndi communication between app servers?

Hi all,
I'm quite familiar with J2EE and its communication architecture. In the past, I haven't had the need to communicate from one app server to another (just all web/applet clients to the central app server). But now I need to :)
Is there a way to communicate (synchronously) between app servers on different machines that aren't clustered? Clustering is not a possibility.
I know JMS is an option, but JMS is asyncrhonous. I also know you can't create server sockets in an app server because the J2EE spec disallows this approach, so forget about client/server communication via sockets.
This would be my ideal solution:
Server A does a jndi lookup for a bean on server B. Server A gets this reference and works with it just like any other J2EE client to server B.
Does JNDI allow you to do lookups to other namespaces outside of the current namespace on server A?
Can this even be done?
Thanks,
Les Hazlewood

Yes. It's possible. For one of my applications, I have three HP-UX servers that run i2 software on them, but for different business units. I have a J2EE application that does a little bit of everything for the i2 applications. Since the business logic is the same, with only the business dept differing, I deployed 3 instances of JBoss, each running on their own server. My user's log into one of the applications, doesn't matter which, and if they request a service (EJB) that needs to run on a different server, my webapp makes a connection to that server and uses the remote EJB to do the work. It's very possible and an excellent solution.
The solution will depend on which J2EE server you're using.
Here's a class I use to retrieve the InitialContext I need for my application:
package com.cibavision;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.rmi.RemoteException;
import java.util.Properties;
public class CibaJNDI{
   public static InitialContext getInitialContext ( String server ) throws javax.naming.NamingException {
      Properties p = new Properties () ;
      p.put(Context.INITIAL_CONTEXT_FACTORY,
             "org.jnp.interfaces.NamingContextFactory");
      p.put(Context.PROVIDER_URL,
             "jnp://" + server + ":1099");
      p.put(Context.URL_PKG_PREFIXES,
             "org.jboss.naming:org.jnp.interfaces");
      return new InitialContext (p) ;
}Using this class, I have logic in my application that calls for the appropriate server, something like this:
if businessA then use server1
if businessB then use server2
if businessC then use server3
I then call for my InitialContext, request my EJB, and I'm off and running. No clustering, it matters which machine I'm on (I have to read extract files, etc.)
Works great. We are also a weblogic shop, but I haven't made any calls to weblogic from outside my J2EE app yet, but it should only differ by the hash attributes you pass to new InitialContext( props ).
Hope this helps,

Call alternating between earpiece and loudspeaker

I have a Sony Z1The last few days when i answer a call I will start the call using the ear speaker (phone held to ear) however after a while the phone begins to alternate between the ear speaker and the loudspeaker and eventually after about 15 seconds i just have to end the call. I don't know if it was an app update on the phone or my SW3 update that is causing the issue.
I have tried clearing a few apps but that does not seem to have helped.
Now not sure if linked but i have a new set of Sony Bluetooth earphones also that sometimes starts and stops when playing music. I thought it might have beenthe earphone battery going flat but it was doing it also when fully charged.
Anyone had similar? I have seen the post where calls go directly to loudspeaker but i thought this was different.

Started to happen again today however the cache was empty. This time however the call alternated between all the options (earpiece, speaker and headphones). I conducted a factory reset and it still occurred. I am now stuck for answers.
Another issue I am getting at the same time is my wifi disconnects and says ' temporarily avoiding poor signal ' when the signal in the wifi section shows full wifi signal?
UPDATE;
I had been getting notifications in the notification bar that 'Smart Connect' had headset connected when there was definetly no headset connected. During a call it was again alternating between the different options of earpiece, headset and bluetooth. I subsequently uninstalled allupdates for Smart connect, but i still had call issues. I have now disabled smart connect and will wait to see if this solves the issue. I am now hopeful that this is the problem. Next would be to find out if it is a software or hardware issue.

Transfering data between FTP Servers.

Dear Friends,
How we can transfer data between FTP servers.
Kindly provide me some step by step guide for the complete scenario,
I need to fetch the the dats from FT P server and send the data to FTP Server of MDM.
How to define Technical and Business system in SLD for above mentioned scenario.

No need of IR if you have to use XI as FTP
refer these links:
XI in the role of a FTP
Similar Threads:

I dont think you would need to add servers as technical systems for this thing.
In case you want to call RFC or send or receive IDOCs from R3 servers you need to make technical systems as ABAP.

How to Break the cluster between Two servers

Hi Experts,
Since Iu2019m new to BOBJ XI R2.I would like to know how to break the cluster between two servers.
Description :
So far we took the copy of QAS Server1 to the new QAS server2 (Through Mirroring Tool ). Now those two servers are cluster together, I can see QAS server1 CMS Name, Cluster Name, cluster member name in QAS Server2 (CMC-> Setting -> Cluster).
Besides in QAS Server1 CMS Name and Cluster name are pointing to the QAS Server1, except Cluster Member (This is still have two members Server1 and Server2).(CMC-> Setting -> Cluster).
In QAS Server1 and QAS Server2 (CMS-> Servers), I can able see both server name under Machine Name tab.
I would like to make those two servers as independent servers. There are two different data source for those two servers. I want to remove the cluster in both servers.
Right now QAS Server1 is running and QAS Server2 is stopped.
If i create/modify a group under new Mapped NT Member Groups in QAS server2 ,it is getting reflecting in QAS server 1.
Could you please tell me the steps to resolve this problem.
BO Version: BO XI R2
Regards,
Sridharan

Hi,
Maybe the external CMS is still 'attached' to your SIA node. Please go to the CCM (Central Configuration Manager) and stop the SIA (Server Intelligent Agent). On one of the tabs you can see if there is an external CMS part of your environment. Delete it and restart the SIA. Retry if you can delete the services now from within your CMS. It may well be that you have to stop both environments and delete each others CMS via the CCM to get it working. If you have not changed any permissions for your Administrator account the security model will not be the one causing this.
Hope this helps...

DHCP: Splitting 10.10.120.0/23 between 2 servers, why exclude?

I understand that best practice is to split a scope between 2 dhcp servers on the same subnet. We have a rather larger subnet 10.10.120.0/23
Server1 with pool 10.10.120.50-10.10.120.230
Server2 with pool 10.10.121.50-10.10.121.230
What's the purpose of expanding the scope in each server and configuring exclusions? If each server have technically a different subnet, there will never be a conflict. I would like to know if there's any benefit to expand the range and add exclusions.
Server1 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.231-10.10.121.230
Server2 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.50-10.10.121.49

If this is your config:
Server1 with pool 10.10.120.50-10.10.120.230 /23
Server2 with pool 10.10.121.50-10.10.121.230 /23
Then those are NOT different subnets. Those are properly split DHCP scopes.
The subnet in this case is from 10.10.120.0 - 10.10.121.255 and that is what you're splitting.
For your second example:
Server1 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.231-10.10.121.230
Server2 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.50-10.10.121.49
This will give you problems:
1) The servers are offering the same IPs, they might even issue the same IP to two different devices because they won't know the other gave it away.
2) Server 1 has some exclusions that Server 2 won't know about. That means Server 2 will issue IPs from Server 1's exclusion range.
3) This is not a recommended setup.
- If you have found my post to be helpful, or the answer, please mark it appropriately.

Communication problem between NetBeans and Tomcat

hi!
i got a quite mysterious problem. here is what happens:
- i start NetBeans 5.5.1 (the first time)
- i want to debug my JSF-Project, the Debugger starts
- After a few seconds the debugger waits for tomcat (it sais: "Waiting for Tomcat...") and tomcat starts
- Again after a few seconds the tomcat-debugger-output sais "Tomcat startet in 3333 ms".
okay.
when i enter http://localhost:8084/ in my browser i get the tomcat homepage, so the server has definitely started! But nothing happens in NetBeans and nothing happens with my project....
In the lower-right corner i see this blue working-bar that sais "deploying project" but nothing happens. The Project-Debugger-Output still sais "Waiting for Tomcat..." but nothing happens...
And after something around 3 minutes (i guess it's a timeout) i get the error "Starting of Tomcat failed." But is HAS started, i can login to the Administration-Area in my browser!
so i guess there is a communication problem between netbeans an tomcat. Netbeans waits for a message from tomcat but tomcat doesn't send it..or netbeans doesn't understand it.
But the story goes on:
When i press the debug-button a second time it takes only a few seconds till i get the message: "Tomcat server port 8084 already in use". OF COURSE! Because Tomcat has already startet and can't be stoped by NetBeans.
i'm trying to solve this problem for 4 days now, so i would be very happy if anyone has an idea where to start/continue the search...
thanks,
flo.

Cannot get Telnet to work between two servers on same subnet

I need to test if communication is open on port 8444 between two servers.
I installed telnet client on a Server 2008 R2 server and telnet server on a Server 2008 SP2 server. I also manually started the Telnet service that was set to disabled on the SP2 server. I disabled the Windows firewall on both servers. They
are both on the same subnet so they don't need to go through any routers and I can ping successfully.
When I try to telnet to the remote server by typing telnet "ip address" 8444, I get an error that says "Could not open connection to host, on port 8444: Connection failed.
I tried other ports like port 80 and got the same error.
What else is needed to get this to work?

VMs have nothing to do with it, as long as there's network communication between the servers.
As I said, there must be a service or application listening on that port for it to respond. For example, try this:
C:\> telnet
When the telnet prompt opens, type in:
open mail.messaging.microsoft.com 25
If it works, you should see this:
220 CH1EHSMHS035.bigfish.com Microsoft ESMTP MAIL Service ready at Thu, 7 Feb 2013 00:57:33 +0000
That means that Microsoft's mail servers are LISTENING on port 25 and it responded. And note, telnetting to port 25 is a non-default telnet port, because port 23 is the default telnet port. When you type in a space and then a port number, you're telling
the telnet client to use that port.
That is the SAME THING if some sort of application or service is listening on port 8444 on that other server you're trying to telnet to. If there is no app or service listening, it will just time out.
And no, installing the TELNET service on that sercver will NOT answer to any port other than 23. The telnet service by default, uses TCP 23, unless you specify otherwise.
So once again, what service or app on that server is supposed to be listening on 8444?

Port forwarding between two servers from Same subnet

Hi,
We have a Cisco ASA 5520 Version 8.4(3). There exists a site to site VPN tunnel between us and a client and the client sends us the data to our local host/server 10.x.x.20 on port 52944. So 10.x.x.20 gets data on port 52944. We want to forward this data to a test server 10.x.x.21( same subnet IP) on port 52945. so basically I want to forward traffic from 10.x.x.20:52944 to 10.x.x.21:52945.
Is this possible. I am a new bee to the networking and still learning. Excuse me if this sounds silly.
I know we can add one more ACL in the VPN tunnel and add this test server IP in the ACL. but, then I have to ask the clinet to change their ACL too. I dont want to do this. So I want to wrok around it. Any help or suggestions is much appreciated.
Thanks in advance :)

VMs have nothing to do with it, as long as there's network communication between the servers.
As I said, there must be a service or application listening on that port for it to respond. For example, try this:
C:\> telnet
When the telnet prompt opens, type in:
open mail.messaging.microsoft.com 25
If it works, you should see this:
220 CH1EHSMHS035.bigfish.com Microsoft ESMTP MAIL Service ready at Thu, 7 Feb 2013 00:57:33 +0000
That means that Microsoft's mail servers are LISTENING on port 25 and it responded. And note, telnetting to port 25 is a non-default telnet port, because port 23 is the default telnet port. When you type in a space and then a port number, you're telling
the telnet client to use that port.
That is the SAME THING if some sort of application or service is listening on port 8444 on that other server you're trying to telnet to. If there is no app or service listening, it will just time out.
And no, installing the TELNET service on that sercver will NOT answer to any port other than 23. The telnet service by default, uses TCP 23, unless you specify otherwise.
So once again, what service or app on that server is supposed to be listening on 8444?
