ICT QSIG Call Preservation

Hi Techs

Does ICT QSIG preserves the call during the following scenario.

CUCM fails in a cluster A. In the lab CUCM service parameter ***Allow Peer to Preserve H.323 Calls *** is set true. But the call is not getting preserverd when the calling IP Phones CUCM goes down.

IP Phone ---> Cluster A CUCM ICT w QSIG ----> GK ----> Cluster B CUCM ICT w QISG ---> IP Phone.

Thanks

Peter

Not supported at this time.

H.323 version 5 incorporated Annex R called "Robustness methods for H.323 entities" which make it feasible.

You may contact your AM since there is already a PERS for this.
