So I am a total newbie in asterisk and managing call lines in general but I managed to install Asterisk Now 13 distro, I have connected 2 sip phones with pjsip and configured a sip trunk which works when I dial an external number with the corresponding prefix. Now I have to programmaticly originate calls and connect them to local extensions which I have no idea how to achieve and I cant seem to find much information about it on the internet after hours of searching.
I managed to connect 2 local sip phones with the asterisk manager api and OriginateAction in the following way:
originateAction = new OriginateAction();
originateAction.setChannel(ConnectionType+"/"+extCaller);
originateAction.setContext(context);
originateAction.setCallerId(idCaller);
originateAction.setExten(tDestination);
originateAction.setPriority(priority);
originateAction.setTimeout(timeoutCall);
managerConnection.login();
originateResponse = managerConnection.sendAction(originateAction, timeoutRequest);
I also tried this channel originate pjsip/201 extension number#from-ptsn and channel originate local/201#from-local extension number#trunkName .
The context of the PJSIP trunk is from-pstn,I tried using that in various ways without luck both in asterisk cli and the application.
How do I make it use the PJSIP trunk when originating the call and make a call out of the office?
EDIT: I originated an outgoing call using a number that completes with the trunk outgoing route requisites and the "from-internal" context like this:
channel originate Local/201#from-internal extension (prefix)numberToCall#from-internal
I still do not understand why this works and if it is the correct answer to my question.
So the answer is in the edit of the question. The only way to generate an outgoing call that I could find is to originate that call "internaly" (with the context "from-internal" which happens to be the same context that is used when originating internal calls) introducing a target number value that completes with the sip trunk's route pattern requirements.
Example:
I have a route configured for the sip trunk( trunk1 ) with a pattern(RegEx): [0]{1}/number/ that means that with a 0 infront of any nubmer it will be a valid value for that route and it will try to call using trunk1.
In the case of AsteriskNow CentOS installation it happens to be with the context "from-internal". Since the asterisk configuration files are owned by the FreePBX it is recomended to use the FreePBX GUI instead of configuring the .conf files of asterisk manualy.
That concludes to :
channel originate Local/201#from-internal extension (0)[numberToCall]#from-internal
Which will make the extension 201 ring first and when picked up it will try to use the sip trunk to dial that [numberToCall] because the route with the 0 is "called".
In order to send that command to asterisk using asterisk-java I wrote the following code:
ManagerConnectionFactory factory = new
ManagerConnectionFactory("serverIp", "username",
"passwd");
ManagerConnection managerConnection=factory.createManagerConnection()
OriginateAction originateAction=new OriginateAction();
final String randomUUID=java.util.UUID.randomUUID().toString();
System.out.println("ID random:_"+randomUUID);
originateAction.setChannel([connectionType]+"/"+[callerExtension]);<-- SIP or PJSIP / 201(the phone that will ring first)
originateAction.setContext("from-internal"); <-- Default FreePBX context
originateAction.setCallerId([callerId]); // what will be showed on the phone screen (in most cases your phone)
originateAction.setExten([targetExten]); //where to call.. the target extension... internal extension or the outgoing number.. the 0[nomberToCall]
originateAction.setPriority([priority]);// priority of the call
originateAction.setTimeout(timeoutCall); // the time that a pickup event will be waited for
originateAction.setVariable("UUID", randomUUID); // asigning a unique ID in order to be able to hangup the call.

Hello I'am building an android app using smack, the server support both the xep-0030 and the xep-0115, smack also support them.
What I want to achieve is the ability to cache on the client the server capabilities in order to reduce the number of disco#info performed by the client on login.
Based on the smack documentation what I have done is this:
EntityCapsManager entityCapsManager = EntityCapsManager.getInstanceFor(xmppConnection);
entityCapsManager.enableEntityCaps();
EntityCapsPersistentCache cache = new SimpleDirectoryPersistentCache(cacheFile);
entityCapsManager.setPersistentCache(cache);
but even with this lines of code result in the client always performing the same number of disco#info
there is a solution to my problem or I have to leave with that?
this is an example of my presence:

I wish to test my web server which have checking to detect abusive API usage by IP address. One IP address is limited to a few hundred API calls per day.
As part of testing & simulation procedure, I need to be able to switch IP frequently & programmatically. How to do this? I am thinking of using publicly available free proxy service (or even TOR) to hide my IP. But I am not sure how to change the proxy settings programmatically.
I am using Ruby but any languages are welcome.
In ruby you can make calls to the command prompt. If I were you I would make a method that uses these calls. To do this use %x command.
Edit----
This is the code I made.
def ipChanger(name,ip)
return %x(netsh interface ip set address #{name} static #{ip} 255.255.255.0)
end
The syntax is "netsh interface ip set address "Your adapter name here" static "new ip" "new netmask" "optional default gateway"
I have a piece of code which uses spring integration's IMAP adapter to poll an inbox to read all incoming emails which are unread and that works perfectly. But if I open any email message and and then mark it as "unread" in my outlook inbox the poller doesn't fetch the marked email.
I can use the pop3 adapter which fetches all the email, but deletes them afterwords, but I want to keep the emails in my inbox and I want the poller to fetch all the email which are unseen.
Any suggestions to handle this problem? I been searching and reading articles on email adapters but didn't find anything useful.
Thanks in advance.
Looks like you need custom 'search-term-strategy'. From Spring Integration (SI) documentation:
By default, the ImapMailReceiver will search for Messages based on the default SearchTerm which is All mails that are RECENT (if supported), that are NOT ANSWERED, that are NOT DELETED, that are NOT SEEN and have not been processed by this mail receiver (enabled by the use of the custom USER flag or simply NOT FLAGGED if not supported). Since version 2.2, the SearchTerm used by the ImapMailReceiver is fully configurable via the SearchTermStrategy which you can inject via the search-term-strategy attribute. SearchTermStrategy is a simple strategy interface with a single method that allows you to create an instance of the SearchTerm that will be used by the ImapMailReceiver.
And here is a post from SI forum with funtastic Oleg's explanation: Server does not support RECENT or USER flags
And here you can find SI DefaultSearchTermStrategy: it's a place to determine how you should implement your own strategy. I guess, you case is:
This email server does not support RECENT flag, but it does support USER flags which will be used to prevent duplicates during email fetch.
Switch SI-mail logging level to DEBUG and take a look, which flag supports your email server.
I have a JBOSS batch application that sometimes sends hundreds on emails in a minute to the same email address with Log4J errors. This causes problems with Gmail, because it says we are sending emails too quickly for that gmail account.
So I was wondering if there was a way to basically create a "digest" or "aggregate" email puts all the error logs in 1 email and sends that every 5 minutes. So that way every 5 minutes we may get a large email, but at least we actually get the email instead of it being delayed for hours and hours by gmail servers rejecting it.
I read this post that suggested something about using an evaluator to do that, but I couldn't see how that is configured in the Log4J xml configuration file. It also seemed like it might not be able to "digest" all the logs into 1 email anyway.
Has anyone done this before? Or know if it's possible?
From (the archived) SMTPAppender Usage page:
set this property
log4j.appender.myMail.evaluatorClass = com.mydomain.example.MyEvaluator
Now you have to create the evaluator class and implement the org.apache.log4j.spi.TriggeringEventEvaluator interface and place this class in a path where log4j can access it.
//Example TriggeringEventEvaluator impl
package com.mydomain.example;
import org.apache.log4j.spi.LoggingEvent;
import org.apache.log4j.spi.TriggeringEventEvaluator;
public class MyEvaluator implements TriggeringEventEvaluator {
public boolean isTriggeringEvent(LoggingEvent event) {
return true;
}
}
You have to write the evaluator logic within this method.
I created a free useable solution for log4j2 with an ExtendedSmtpAppender.
(If you still use log4j 1.x, simply replace your log4j-1.x.jar with log4j-1.2-api-2.x.jar - and log4j-core-2.x.jar + log4j-api-2.x.jar of course.)
You get it from Maven Central as de.it-tw:log4j2-extras (This requires Java 7+ and log4j 2.8+).
If you are restricted to Java 6 (and thus log4j 2.3) then use de.it-tw:log4j2-Java6-extras
Additionally, see the GitLab project: https://gitlab.com/thiesw/log4j2-extras (or https://gitlab.com/thiesw/log4j2-Java6-extras)

If you use log4j2, see answer to other stack overflow issue: https://stackoverflow.com/a/34072704/5074004

My services file (C:\WINDOWS\system32\drivers\etc\services) has a bunch of Port to Service mappings:
echo 7/tcp
echo 7/udp
discard 9/tcp sink null
discard 9/udp sink null
systat 11/tcp users #Active users
systat 11/udp users #Active users
daytime 13/tcp
daytime 13/udp
qotd 17/tcp quote #Quote of the day
qotd 17/udp quote #Quote of the day
chargen 19/tcp ttytst source #Character generator
I am trying to find a way to convert from a Port to the Service Name programmatically through Java APIs (instead of parsing) or third party libraries?
Pseudocode:
Port port = new Port("443","tcp");
String service = port.getService();
System.out.println(service); //prints "https"
Is there any good way to accomplish this?
What you are looking for is a Java implementation of the Linux getservbyport() system call. Take a look at http://github.com/wmeissner/jnr-netdb. Also, do a Google search for java getservbyport
I don't think there is some API in java for this purpose.
You will either need to parse this file or maintain port service mapping in some form (Properties file,db etc.).
example to parse from system file is :
