Hello,
I'm having a problem with any application that runs ok in the same network of CUCM, but when I change to other network (I've got a static mapping of my IP address and permit all IP traffic between this 2 DMZs - private and voice - no routing problems, no DNS problems), I allways get same error:
"com.cisco.jtapi.PlatformExceptionImpl: Unable to create provider -- null"
Why do I have this problem ? It's the same machine, just change networks ??
JTAPI need same network between CUCM and Client App ?
JTAPI doesn't support routing ?
Thanks
Miguel

Are you able to ping CUCM from client app machine? Client App machine would try a connection to CUCM over port 2748 or 2749, so just ensure if these are not blocked and are reachable from client app.

Hello,
Sorry, just saw your post today...
Like I said, all traffic is permited between 2 networks (including ICMP) and I can see connection over port 2748, but no traffic response from CUCM.
Thanks anyway

It sounds like a connectivity issue and I cant think of any other obvious issue here.
I would suggest checking:
- if CallManager/CTIManager services are running.
- if in case you have done any call manager upgrade recently, check the db replication status and fix if needed.
- check rtmt for any alarms/errors indicating any environment / network issue.
If it is still an issue, i would suggest opening a support case after collecting JTAPI, Calll Manager, CTI Manager and sniffer traces.
