Plantronics + Polycom.
Now together as
I hope you can help me to find a solution.
I need to connect Polycom DMA 5.2 with Cisco CUCM 8.03As 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
