Examples with EventHeader javax.sip.header.EventHeader used on opensource projects

Example 1 with EventHeader

use of javax.sip.header.EventHeader in project camel by apache.

the class SipPresenceAgentListener method processPublish.

private void processPublish(RequestEvent requestEvent, ServerTransaction serverTransactionId) {
    try {
        Request request = requestEvent.getRequest();
        LOG.debug("SipPresenceAgentListener: Received a Publish request, sending OK");
        LOG.debug("SipPresenceAgentListener request: {}", request);
        EventHeader eventHeader = (EventHeader) requestEvent.getRequest().getHeader(EventHeader.NAME);
        Response response = sipPresenceAgent.getConfiguration().getMessageFactory().createResponse(202, request);
        sipPresenceAgent.getProvider().sendResponse(response);
        // Send notification to subscriber
        sendNotification(eventHeader, false, request.getContent());
    } catch (Exception e) {
        LOG.error("Exception thrown during publish/notify processing in the Sip Presence Agent Listener", e);

}

Example 2 with EventHeader

use of javax.sip.header.EventHeader in project camel by apache.

the class SipPresenceAgentListener method processSubscribe.

        } else {
            response = sipPresenceAgent.getConfiguration().getMessageFactory().createResponse(200, request);
        }
        // Both 2xx response to SUBSCRIBE and NOTIFY need a Contact
        response.addHeader(sipPresenceAgent.getConfiguration().getContactHeader());
        // Expires header is mandatory in 2xx responses to SUBSCRIBE
        response.addHeader(sipPresenceAgent.getConfiguration().getExpiresHeader());
