Well, the message almost got through with format corruption. For those without the emoticon to text reversal plugin, the field you're going to access for the B-channel is of the format " : DS0" without the spaces.

In VoiceXML you can access a SIP header using the session variable session.com.cisco.proto_headers[''], for example, session.com.cisco.proto_headers['Remote-Party-ID']. Sample VoiceXML output from a custom element is attached; you can see a selection of headers being retrieved. To get the B-channel ID itself you have to retrieve the Via header and parse the DS0 number from the x-ds0num header field. I've attached a custom element that will retrieve the headers configured in the element settings and create data for each of the fields. In the B-channel example, using this custom element, the relevant information would be written to ElementName.Via.x-ds0num. The actual value you're interested in still needs to be parsed-out but this gets you pretty close. For a BRI the DS0 field looks like this: x-ds0num="Basic Rate Interface 0/1/0 1:DS0" so you just need to extract the value from the x:DS0 part. It's very similar for a PRI. In comprehensive model, the Via header on the VRU leg won't include the x-ds0num field as CVP doesn't propagate it but there's a couple of things you can do very easily provided you configure the CVP Call Server to pass the Via x-ds0num field up to ICM. In the ICM script you can either parse out the B-channel number from the x:DS0 field into a call variable or just write it to a custom SIP header before invoking the SendToVRU if you don't want to use up variable space.

--------------------------------------------- Paul, I'd love to know how to know how to get the B-channel ID. Please post the vxml. Also - if this is done in a Comprehensive environment, then how does ICM retrieve the data and pass it on to the Studio application? -- Janine Graves

Sure, I would be interested to know how to get this ds0-num using Custom VXML in Call Studio.

If you do want to access the B-channel ID there is a way to do it but you would have to insert a SIP call leg if this is standalone model. Enable ds0-num under voice service voip sip on the gateway. That will cause ISDN B-channel info to be included in the SIP Via header in the x-ds0num field which you can access from your Studio script using a bit of custom VoiceXML. Not sure if I posted that already but let me know if you need it.

I did consider taking a mod 60 on the router call key but the uniqueness within the back end system was still an issue. I like the suggestions of a database with record locking or thread synchronisation. Thank you for these. I'm leaning towards the database at the moment as it potentially helps with another ID that needs to be replicated. Keith

However if you want a pattern from 1-60 only, you cannot reset that. Router call key can get quite large depending on no of calls you get.

You can easily implement the record locking at database level. Alternatively you can use threading and use synchronized feature to prevent concurrent access.

Keith, Yes, multiple applications can read the values of global data at the same time using custom java. How large can this number be? Can't you use the ANI? You wouldn't have more than one call from a phone number at a given time, would you?

My assumption was not that. Anyways, if that is the requirement than that too can be done. All you need to do is to look for which no got freed up from the database and have a method that checks for all such conditions and assigned the next one. The requirement needs to be defined further. It’s java and any logic can be coded.

If you do not want to use session ID, you can write your method to create something equivalent. You can have port counter in database which the system reads and increments each time a call comes in. (from 1 to 60). Depending on no of calls you get, you can reset that counter back to 0 or 1 when it reaches 60. This will ensure that each call will have a unique ID with respect to the backend.
