Hello, I have an install that is coming up that will involve an integration between a Callmanager 5 system and an existing Avaya Definity G3R system. I have a 2851 as the gateway between the two systems with the intention of using T1 CAS with a H.323 config. I have read some posts regarding T1 CAS E&M Wink not supporting DNIS/CallerID information and that Feature Group D may be needed. Now these posts are mostly referencing with Telco's and not Gateway to Definity. I was wondering if I am going to need a similar configuration for my integration or will E&M Wink on both ends work just fine? The sample config document by Cisco does not mention any issues regarding DNIS but I'd like to hear from anyone who has this config in production or a similar config.
Thanks in advance!
