Dear VG team,



i was looking for a result variable to determine the call to which route to go, then i found $RV_DNIS, but i were facing a problem that once i sued it's showing me an old IP address, please find the attached VG engine and config.xml.

There are over 100 calls in that vgEngine trace and the DNIS for all of them is the same:


Can you explain in more detail what do you mean by: "it's showing me an old IP address" ? What is the DNIS that you were expecting?

in the config.xml i used to register the <RegClient> with this IP ,and it's still showing the same.

note : all my calls coming from Avaya IPO V2 thru a SIP trunk

Avaya IP address is :

Can you describe in more detail your network setup?


It looks like you have a SIP trunk pointing to the VoiceGuide IVR, and looks like you are registering it at restart time (but not Authenticating?).


It looks like the IP address of VoiceGuide system is, and IP address of the Avaya IPOffice which is providing the SIP trunk is


What is the address of?


Is maybe the address to which the calls are routed it initially?, and then routes call to which then routes call to ?


It looks like the system at and the system that is sending call to is not passing on the number dialed, but is placing the in the DNIS field.


Looking at WireShark trace will let you better see what information is supplied with the call, and sounds like you may want to run WireShark traces on traffic between and the Avaya IPOffice, and probably on traffic arriving into the as well.

Dear VG team,


VoiceGuide system was configured with this IP earlier  then we have changed it to and in my network there is no more

that's why am wondering that  it's appearing in Vgengine logs as DNIS.

Dear VG team, 


You are correct i have found in the wire shark and on IPO that's still there i have chagned it and am getting the bew DNIS , but i apprecaite your support to how to determine based on whch DNIS i can route the call by using the evaluate expression.

Thank you very much

If DNIS information reaches VoiceGuide then VoiceGuide can use it to route calls etc.


Right now it looks like this information is lost by one of the switches in the path of the call route. You will need to ensure that those other switches pass on the DNIS information.
