CISCO CUCM 8.03 trunk to DMA

Hello Everyone,


I hope you can help me to find a solution.

I need to connect Polycom DMA 5.2 with Cisco CUCM 8.03
As far as I know CUCM in this version has some problem with SIP signaling issue, and its working well from 8.6.

 

But I have 8.03 with no chance to upgrade it.

 

I was tried to do that on H323, but I have no idea how, can help me with this? or maybe you can let me know any other idea how route calls from PBX to PSTN

 

I need to find solution quick.
I have RMX CMA DMA VBP-E VBP-ST

 

Thank you in advance
