dual forking LBG and mediation server

[Mitelpassion]

has anyone done LBG dual forking with mediation server??

I'll list my questions if someone has. Have some questions on the SIP trunks and can the dual forking be done without the mediation server

I am currently experiencing the joys of ocs integration without lbg and have dual forking working with dynamic extension but there are afew hiccups. The SIP trunk to the mediation server works fine and sip messaging is correct. You will require mediation server between ocs and 3300 for the following reasons :

The Mediation Server performs the following main functions:
• translates SIP-over-Transmission Control Protocol (TCP) from the 3300 ICP to
SIP-over-mutual-Transport Layer Security (TLS) for the OCS 2007
• translates SIP-over-mutual-TLS from the OCS 2007 to SIP-over-TCP for the 3300 ICP
• encrypts and decrypts Secure Real Time Protocol (SRTP) on the OCS side
• translates media streams between OCS 2007 and the 3300 ICP
• connects clients that are outside the network to internal Interactive Connectivity Establishment
(ICE) components that enable media traversal firewalls.
• acts as an intermediary for call flows that the 3300 ICP doesn’t support, such as calls from
remote workers on an OCS 2007 voice client.

Im not sure if you still need mediation if you have lbg

mmm, I think you need LBG for RCC (remote call control)
documentation clearly states that you require Unified Communicator mobile for dual forking and that the personal ring group (dynamic extension) is not supported.

are you saying personal ring groups working fine for you?

 

[Mitelmatt]

Mitelpassion, you are correct mate, RCC MUST have the LBG or it won;t work! The LBG converts the messaging.

You can create SIP softphones on the 3300 from OCS without but to do dual forking you need LBG

What's your questions?

Yes Ive got personal ring groups with EHDU working. The only fault I have is that when an pstn call comes into the EHDU(logged in on moc) and if the pstn caller hangs up, the moc client is presented with internal dialtone(i.e expecting the EHDU to perform another internal task) The moc client has to click hang up, to clear down the call. But this is how dynamic extension was designed, it also does the same if the EHDU is a mobile phone. It is a very minor fault that the MOC has to click hangup, even though is disconnect is sent from the pstn. But it does work even though as you say unsupported.

 

[TrunkMan]

mitelpassion, which document states that dynamic extension isnt supported ?

 

[Mitelpassion]

personal ring groups more than dynamic extension
(isn't it the same - dynamic extension and personal ring groups)
the release notes say this.

 

[Mitelmatt]

Dynamic extension wasn't supported in first release of MCD 4. It was officially supported in 4 SP1 or 2 i think. There was a bulletin on it.

TrunkMan, be very surprised if you get the full dual forking with RCC working without LBG.

 

[TrunkMan]

Our customer isnt looking for RCC. All they want is the Moc client to ring as well as the desk phone. Only require dual forking.

 

[Mitelpassion]

is dynamic extension and personal ring group not dependent on each other, at least one way dependent.

 

[Mitelmatt]

in a round about sort of way that's what i was asking, sorry!

In that case cool, yeah good work.

Mitel passion, to have just the MOC working as a sip client it's direct integration, it's documented. The you can put it in a personal ring group.

Dynamic extension is just marketing name, consists of Personal Ring Groups, External Hot Desking and Group Presence. Can be used independently or together

 

[Mitelpassion]

thanks,

I get that you can get the MOC to work as a softclient but for Dual Forking I'm not sure...

dual forking will allow the desk phone and the MOC soft phone to ring simultaneously if they require this feature and for this the release notes state that you need mobile extension and that personal ring groups are NOT supported.

Release notes for LBG 3.1.

Needless to say I'm confused!

 

[Mitelmatt]

I think there's confusion in the terms used here.

Trunk man, dual forking in your term is not the same as the true OCS Dual Forking that Mitelpassion is on about.

All Trunkman is doing is "dynamic extension" with an MOC Softphone.
