Unity 7.02 / 200 ports / 5000 users - is there a maximum number of routing rules supported with this config? We are currently trying to determine the best way to integrate several Avaya systems using PIMG and may need to use routing rules to do so....What are the overhead /considerations? Also, is the extension remapping tool still available in 7.x?
The EXM file parsing (extension remapping) may still be in the MIU, however it hasn't been supported in some time.
there's no real practical limit on the number of routing rules from a performance standpoing - I've seen over 1,000 before. A large number of routing rules can be a real pain to administer via the web interface however - it's not designed for handling that many. But it wont break anything. Use a good naming convention for your rules up front - you'll be glad you did later.
