It's an used accessor at this point, but might as well correct it.

    /**
     * Gets the upper boundary of available range.
     * @retun min port number
     */
    public int getHighestPort() {
        return portManager.getLowestPort();
    }

Add announcement support to custom endpoints imlemented for sbc.
this may be complicated since mixing is not supported in this endpoints and not 
always mms will do transcoding ( it may use codec negotiated between 2 sides 
even without having it implemented ) , therefore it will not always be possible 
to transcode audio to correct destination codec

Add Video SS7 Support

Add H.248 Support for Media Server

Add H.263+ Codec Support

Add Video Conferencing Support

Media server could not handle with Media Format:97 telephone-event.  When  
incoming  SDP Offer  contains  rtpmap:97  telephone-event/8000,   the replied 
SDP Answer doesn't contains this  Media Attribute type.   Then cause fail to 
detect DTMF on that call session.

To solve this issue
Yulian Oifa suggest  making the following change:
In 
https://code.google.com/p/sipme-media-server/source/browse/io/rtp/src/main/java/
ua/mobius/media/server/impl/rtp/sdp/RTPFormats.java#192
Change from
for (int i = 0; i < this.rtpFormats.size(); i++) {
    for (int j = 0; j < other.size(); j++) {

        if (this.rtpFormats.get(i).getFormat().matches(other.rtpFormats.get(j).getFormat())) {
                        if(this.rtpFormats.get(i).getFormat().getName().equals(AVProfile.telephoneEvent.getName()))                            
                                res.add(this.rtpFormats.get(i));                    
                        else if(!hasNonDtmf)
                        {
                                res.add(this.rtpFormats.get(i));
                                hasNonDtmf=true;
                        }
                }
    }
}


To:
for (int i = 0; i < this.rtpFormats.size(); i++) {
    if(this.rtpFormats.get(i).getFormat().getName().equals(AVProfile.telephoneEvent.getName()))                            
        res.add(this.rtpFormats.get(i));
    else if(!hasNonDtmf)
    {      
        for (int j = 0; j < other.size() && !hasNonDtmf; j++) {
            if (this.rtpFormats.get(i).getFormat().matches(other.rtpFormats.get(j).getFormat()))
                        {
                                res.add(this.rtpFormats.get(i));
                                hasNonDtmf=true;
                        }
                }
    }
}

Add P2P ( SBC based without conferencing support ) Video support

GSM EFR implementation for Media Server

Currently implemented over mgcp and uses threads and runnable in non optimal 
way.
Need to add built in support for JSR in media server and reimplement driver 
based on new support.

More Details :

https://groups.google.com/forum/#!topic/sipme-media-server/J7WOR0aArxE

In this mode sbc should set to top of list codecs received from first UA, but 
will add supported under transcoding codecs after that.Depending on answer 
received from second UA endpoint will work either as pass through ( if both 
sides support any of codecs ) or transcoded otherwise.

Test maximum load for OPUS codec.
Set target and optimized implementation

When other side does not supports OOB currently ignores and does not sends data 
, should translate it to inband and send

Add H.264 Video codec support.

Test maximul load for GSM + GSM EFR codecs.
Set target and optimize both codecs

Add RTCP mux support for Media Server

Add RTCP support for Media Server

Add Standalone ( Independent ) centralized management interface that will allow 
to manager all the server for specific company.
Implement web interface , add web services support to allow querying data for 
other apps that may be used already.

See thread:
https://groups.google.com/forum/#!topic/sipme-media-server/9nv2WGDbY6A

Implement driver for db access to obtain MMS configuration , logging storing , 
etc.
At first step use cassandra NOSQL DB.Other may be added in future depending on 
community interest

Add SNMP monitoring support.
Add endpoint , resources and connections params

1. Bugs exist in 
org.mobicents.javax.media.mscontrol.mediagroup.MediaGroupImpl#nextRequestID
2. Constructor of jain.protocol.ip.mgcp.message.parms.RequestIdentifier is 
expecting unsigned hexadecimal string.
3. Exception thrown when 
org.mobicents.javax.media.mscontrol.MediaSessionImpl#getUniqueReqID reaches 
80000000, 
 java.lang.IllegalArgumentException: Request identifier must contain between 1 and 32 hexadecimal digits!

Code to quick test:
    public static void main(String args[]){
        int reqId = 0;
        while(true){
            try {
                new RequestIdentifier(Integer.toString(++reqId));
            } catch (IllegalArgumentException ex){
                ex.printStackTrace();
                break;
            }
        }
    }

What is the expected output? What do you see instead?
org.mobicents.javax.media.mscontrol.mediagroup.MediaGroupImpl#nextRequestID 
should not throw exception when integer overflow. 


What version of the product are you using? On what operating system?


Please provide any additional information below.

Currently mms runs stable therefore logging of datetime is not enough to get 
more details for specific event.
Need to change logging format to include date also

Test maximum load for g729 codec.
Set target and optimize codec to reach the target

Add Fax Support to Media Server

Allow Connection state timeouts configuration in management interface.
Currently are static / non configurable

Need to add adaptive jitter buffer support for mms.
Currently it has static size and does not takes into account client network 
which may produce delay / jitter much higher then 60ms and therefore cause bad 
audio quality.

Add RTP/AVPF Support For Media Server

Add Opus support to media server.
Planned to be added both native ( webrtc based ) and java based implementations.

Add support for Secure Real-time Transport Protocol (SRTP) / (IANA SDP code 
RTP/SAVP) for Media Server

Add Video Player And Video Recording implementation

Test maximum load for ILBC codec.
Set target and optimize codec.

Add compilation for native ilbc + native opus for windows
Modify bootstrap pom to copy files automatically to native folder even when 
file does not exists.

Add custom endpoint implementation which will negotiate sdp based on UA's sdp 
received ( thus codecs received from first UA connection will be duplicated to 
second one ).

Add Secure RTP Support for (RTCP)-Based Feedback (RTP/SAVPF)
