One of our customer has CM 6.x , Unity 5.x and Mitel SX 200 . Thye have Unity for CM phones since they like Unity they want to do dual integration now for VM.
CM integration no problem now for Mitel do we have to go with Analog PIMG's with SMDI connection ??because I couldn't find any documents on Cisco to do digital PIMG's for Mitel SX200.
I was also reading little about QSIG trunking with ISR's and integration with Unity 5.x and PBX, Can we use that here and eliminate PIMG ? If we use this how do you integrate this ISR with Mitel a regular QSIG T1 for voice ports or ?
Thanks for your help.
