Hi there,

I need help with the Presence Services SDK (LPS API).
Environment:
Avaya Presence - Platform Information:
Presence Services 6.2.3.0 Build: 317, Patch 1: 6.2.3.01, Patch 2: 6.2.3.2, Patch 3: 6.2.3.3, Patch 4: 6.2.3.4

LPS API:
Version 6.2.4.0-SDK-1.0-SNAPSHOT
Date: April 15, 2014

I created a java-project in eclipse and included the presence java sdk. Then I created a keystore with java's keytool and added the certificate from presence, the issuer (SystemManager-Certificate), "SIP Product Certificate Authority" and "Avaya Product Root CA".

The private-certificate from the keystore (that is automatically created) was exported and added on the presence server with the commands:
prescert import pem <edge_ca_file>
prescert exportTS

Here is the java-code copied from the DevGuide:

public static void main(String[] args)

		LpsProvider provider = LpsProvider.getLpsProvider();

		// 1. Get the instance of LpsProvider

		Properties lpsProperties = new Properties();

		InputStream inStream = new FileInputStream("LPS.properties");

		lpsProperties.load(inStream);

		inStream.close();

		// 2. Initialise the instance using start(Map properties)

	

		provider.start((Map)lpsProperties);

	}

In the LPS.properties I have set "localdb.ping_db=false" for testing only the SIP-Presence-Communication. All other config-values, except the hostnames and systemmanager-credentials, uses the default-values.
My problem seems to be, that the backchannel from the Bulk-Subscription-Service (S2S) to my workstation port 9072 can not make a SSL-handshake.
The Presence Server accepts the SIP-SUBSCRIBE-Message from my pc and answered with SIP/2.0 200 OK.
After that response, the presence server wants to send a notify to my station and this failed.
Then the LPS API sends a second subscribe with response "481 Reason: Call Leg/Transaction Does Not Exist", I think because of the failed Notify requet.
The LPS-API logs (see attachments) the Exception "recv failed" and "bad_certificate".

The transport is secured via TLS and is working for communication from my station to presence. I think the problem is the communication for the backchannel (presence S2S to my station) but I'm not sure about this.
Can anyone help me?

Attached "log_lps_java.txt" shows the logmessages from lps-SDK after the call of provider.start((Map)lpsProperties);
presence_log.txt shows the debug log-infos from the SIP_BULKSUB while provider.start() of the client.

Thanks in advance
Daniel

Hi Daniel,

This forum is for the Basic Development Environment. As such, members here do not generally have any experience with with Presence Services SDKs.

I do not think there is a suitable forum for your query so I suggest you open a Technical Support ticket using the menu above. One of my colleagues may be able to help you. Please note that, for non-paid members, there may be a fee for this service.
