Reading along with this thread I had very similar reaction to Richard’s and felt the need to chime in here.  


Telchemy’s SQmediator platform features similarly themed, customer configurable, call leg correlation logic to achieve the desired behavior…. which is generally to produce an a fully correlated end-to-end view of service quality.  Like Palladion/EOM, Telchemy products are a commercial product. With that comes premium service, support and true carrier class scalability and like you all, we need to pay to keep the lights on.  In addition, it’s Telchemy’s network of VQmon licensees (e.g. Polycom, Cisco, Yealink, Velocloud, Adtran) that Telchemy has built that enable platforms like these to gain these end-of-line quality insights using scalable, reliable, accurate and portable embedded analysis technology.


And also like Richard – I appreciate the opportunity to comment. 😉


Questions / comments – happy to engage offline.

Indeed Anthony. Apologies, if I fail to restraint myself from chipping in here…. ;)


As long as there is something to correlate on (even as far down as SDP) [which there always is] Palladion/EOM/Oracle Communications Operations Monitor has always supported the functionality to tweak what we call the Call Merging Algorithm to ensure all legs of any call flow are correlated into one view/message flow/ladder diagram. Since we introduced the product to North America in 2008, we’ve never been defeated on this.


The downside is, yes, it’s a commercial product. However, at the end of the day, if the objective is productivity and ROI, may the commercial product be right for the business?


Thanks for the opportunity to comment ☺

best regards

Sounds like a crappy way of correlating a call especially if u have several b2bua’s.  Several commercial products out there that have multiple ways of correlating a call.

If you click on the ‘Merge’ dropdown while displaying the Legs by Header, you can select ‘SIP History’ to display the SIP Ladder diagram of all the legs together.

Hi Matt,

Here's what I've done to get close to what you're looking for...


In the BroadWorks Application Server, set these parameters:



sendCallCorrelationIDAccess = true

sendCallCorrelationIDNetwork = true



Once you do that, you'll see BroadWorks start to add a header for "related" calls. They will have have a common correlation header (but different call-id) like this:





Then, in voipmonitor.conf you can set this parameter in the sniffer configuration to keep track of that header's value in the database:


matchheader = X-BroadWorks-Correlation-Info



VoIPmonitor won't merge them into a single SIP Diagram (at least not that I've found)-- but you should start to see the "related" call legs (with different Call-ID's but the same X-BroadWorks-Correlation-Info header) show up in the "Legs by header" tab when you're looking at a call's details in the VoIPmonitor GUI.

We currently have Broadworks/AcmePacket handling calls to/from customers.  We have a couple VoipMon sensors running watching all traffic inside/outside our SBC.   Currently calls are presented in VoipMon as two different calls (PSTN -> Broadworks & Broadworks -> Polycom) or (Polycom -> Broadworks & Broadworks -> PSTN).     The Call-id on each call is different,  Broadworks generates a new SIP Dialog for the call.   If the customer has a hunt group there could be several INVITEs going out to multiple phones, all with different Call-Id.     Does anyone know of a way to get VoipMon to merge the calls into a single CDR/SIP Diagram?  Is there a way to configure Broadworks to embed the original Call-Id in the new INVITE (Parent-Call-Id Header)?


I’m running R20sp1
