Unity Connection 8.X SMDI integration with Centrex

[glenn.martindell]

Hello,

I'm planning a deployment with CUC 8.x with Centrex phones.   The plan is to use 8 T1s with a single SMDI link.   I've been verbally told by Cisco TAC that a single SMDI link will support 8 T1s (192 channels) but I cannot find any documentation that supports this.   Does anyone know what the limit is for number of channels a single SMDI can support and where I can find documentation to support this number?

Thanks,

Glenn

Hey Glenn,

Please see the following link below.  It doesn't talk to how many T1s are supported it mainly pertains to how many sessions Unity or Unity Connection supports with the TIMG.  Unity supports up to 200 and Unity Connection supports up to 144.  You can stack as many TIMGs up to the maximum session limit for the specific voicemail application.

Hope this helps.
