We have a dial plan that's growing in complexit as we add sites. We're using tail end hop off so that we can dial to a remote gateway and hit the PSTN without incurring LD charges. This is all fine and good, but the problem is that it's getting insanely complicated to document and configure.
I see the way Cisco documents it in their SRND (with CSSes, leading to partitions, leading to RLs, leading to RGs, leading to gateways. That's lovely, if you have like 10 route patterns. However, multiply that by about 10, and it quickly becomes almost impossible to document it all out (lines going everywhere etc.).
Anyone have an suggesions on how you can draw it out in an elegant way so that you could actually follow it? Utilities would be great if there was one. There's the old standby of Visio, but I'm just looking for a good way to tame this beast.
Any suggestions? What are people doing with REALLY complicated DPs?
