IPMA Assistant Console: “System Error: Please contact Administrator”

Version of CCM used 4.1(3)sr2

I have setup a 2:1 (manager (lukes & hans) : assistant(leiao)) IPMA shared line config for the first time (successfully setup 1:1 shared line configs before) and once the assistant loads IPMA Assistant Console (IPMA AC) on PC1, enters her IPMA AC credentials, click OK the assistant gets the following error message “System Error: Please contact Administrator”. I can confirm that IPMA AC works on PC1 (XP Pro SP2 Windows FW disabled) as other 1:1 assistants can log into IPMA AC successfully. leiao also gets the same message when she logs into PC2 (XP Pro SP2 Windows FW disabled) and PC3 (XP Pro SP2 Windows FW disabled ) that have IPMA AC installed. From a telephony point of view all IPMA setups (1:1 & 2:1) work as expected its just IPMA AC doesn't work for 2:1 IPMA shared line setups.

I have deleted lukes, hans and leiao device user profile and user profile, restarted the Tomcat IPMA service and re-created the profiles and still the same problem. In desperation I have even rebooted the CCM Pub & Sub and still leiao gets the message above.

I have noticed looking at the IPMA Service trace logs on CCM that CCM recognises leiao user as a ProxyLineAssistant instead of a SharedLineAssistant like all other 1:1 assistants?? I setup the managers and assistants in the 2:1 config the same as 1:1 shared line config but CCM appears to think that leiao is a ProxyLineAssistant??

Does anyone have any hints or tips on how to solve this, any further info required please let me know :-)

Thanks for your assistance :-)

Kind regards



Re: IPMA Assistant Console: “System Error: Please contact A

delete the old assistant (DWAssist). Remove it from the manager's IPMA configuration and substitute it with a new assistant (DWAssist1). After reconfiguring IPMA accordingly, restart tomcat services
