I am curious to know a best practice for a dial plan based on Local Route groups and the behavior of CFWDAll.
Assume all NANP patterns point to the SLRG and the CFA CSS is the same as the Line/Device(whether it's Activating Device/Line CSS or default). If a phone in site A calls a phone in Site B, which is CfwdAll to a PSTN number, the call will egress the Site A's Gateway, which is undesirable.
A solution is to use site specific CSS/Patterns, RL->RG's...but this negates the advantage of non-site specific patterns you've gained by using the SLRG in the first place.
Any work around for this?
