VCS Control/Expressway appending serial number to IP

I just setup CUCM 9.1 to route IP based video calls to our VCSC/Expressway. Using this doc http://www.cisco.com/c/en/us/support/docs/unified-communications/telepresence-video-communication-server-vcs/118884-config-vcs-00.html#anc .

The setup seems to work correctly as the the call gets passed to the VCS control. However, somewhere in the call chain the IP that I am calling gets the call serial number appended to it. So, the call never gets connect. If I call the IP using the old movi client it works fine.

for example:

  • SubSearch (2)
    • Type: Admin Policy
    • Action: Proxy
    • ResultAlias (1)
      • Type: H323Id
      • Origin: Unknown
      • Value: 103.272.251.20;box-call-serial-number=a507c563-bd28-4231-87c9-4a8f6804766d

Any ideas as to why its appending the call serial number?

Thanks

Having the registration serial number appended to the destination is something that might happen, and shouldn't affect the call.

The guide you linked to is only meant if you're dialing endpoints via IP address, since CUCM is SIP only, it can't call IP addresses like VCS or standalone endpoints can, so that guide is meant to provide a workaround in cases such as that.  You should follow the VCS and CUCM Deployment Guide (CUCM 8,9,10,11 and X8.8) and make sure your VCS-C/E is configured correct per the VCS Basic Configuration (Control with Expressway) Deployment Guide (X8.7), both of these guides will allow endpoints between your CUCM and VCS to connect to each other.

That's correct. We work with several vendors who still do IP based video calls. I can call those vendors now from Cisco Movi which registers to VCS-C. Since I am moving from Movi to Full Jabber i need to use this workaround. I can see the call get routed from Call Manager to the VCS. (and the transform gets applied) Eventually the calls give up with a 404 error.

Appears there might be a CPL in place or something that might be altering the address being searched, see under:

SubSearch (2)
Type: Admin Policy

The IP address is fine, until it hits this subsearch, which applies some kind call policy, identified by "Admin Policy".

Hhhm... I went and looked at Config>Call Policy and I didn't see anything listed on either Control or Expressway. Is there anywhere else I should look?

I just did a test and noticed that from Jabber Video (Movi) calling an H323 endpoint by IP address, it uses my Local Zone search rule that is setup to match "Any IP address".  Do you have a search rules similar to this on your VCS?
