Thanks!
Although there were separate links for Zap and DAHDI in the twiki, I did not find anything that tied to versions - there were references to v2.3.1.x but none on v2.3.2.x.
Which versions of SAIL are okay to install with Asterisk v1.6.x ?
Does FreePBX for SME tie in with SME just like SAIL - all links on the Navigation Panel?
Are there any differences in functionality between the SAIL v2.2.x and v2.3.x versions other than the Zap / DAHDI driver channel changes?
