Clarification require on iwf@VCS_IP_Address

Hi Soundar,

this could be possible that there might be an interworking happening on the calls and that's the reason it is swhowing iwf@vcs ip-address.

however you haven't define what's your scenarion when do you see this error ?

rgds,

Clarification require on iwf@VCS_IP_Address

I've seen this once, someone called in our video network and it came up in the search as @vcs-ip-address instead of @domain.  This was because the device doing the calling only supported IP dialing, they were dialing in the method of alias@vcs-ip-address.  To get around this, I put in a transform into our VCS that will transform the @vcs-ip-address and stip the IP off of the called address, alternativly you could replace vcs-ip-address with a domain.

Option #1:  Remove IP from IP URI

Pattern Type:  Suffix

Pattern String: @%ip%

Pattern behavior:  Strip

-OR-

Option #2:  Remove IP from IP URI and replace with domain

Pattern Type:  Regex

Pattern String: @%ip%

Pattern behavior:  Replace

Replace string:  \1@domain

Note:  %ip% will match any IP address assigned to the VCS.

Hi Patrick

Can you please tell me where i need to put this tranform VCSe or VCSc.

At present below transforms we applied on VCSe

Priority State Description Pattern Type Behavior Replace Actions
1EnabledRemove Domains(.*)@%localdomains%.*RegexReplace\1 View/Edit









3EnabledStrip IP of VCS-E(.+)@203.145.X.X.*RegexReplace\1 View/Edit

There are two options, you could put the transform on just the VCS that you are seeing the alias@vcs-ip-address issue on, or you could put it on both VCSs (C and E).

Hi,

do you recognize 10.10.142.130 address ?

you need to harden your security as some bad guys try to come in with typical 100@1.1.1.1 address. how? TAC

iwf@ip-address is interworked call

Hi Ahmad

It's our VCSc IP address.

The transforms used to not look good as you strip away the local domains, which causes

such kind of trouble.

The basic vcs-e / c deployment guide is a good example on how to build your search rules.

In addition also check that your registrations are proper, h323 and sip shall use both

the full uri with the domain as its registration address.

HI Martin

Thanks for your suggestion. We will check the transforms rules and we got a another alternative solution from your old post (https://supportforums.cisco.com/message/3401571#3401571) We enable the CPL on VCSe and now hackers get the forbidden msg.
