[asterisk-users] problems with PJSIP install on UBUNTU 14.04

[Ryan, Travis]

Yes, the schema can change between versions. Following the instructions on https://wiki.asterisk.org/wiki/display/AST/Setting+up+PJSIP+Realtime#SettingupPJSIPRealtime-InstallingandUsingAlembic
will cause alembic to upgrade the tables.

I'm not a fan of alembic at all, but I'll give it another try. 

One issue I have is I don't want it to make the extensions table, because I already use that name of table for some proprietary stuff I use. Right now it's complaining that I already have a table named that. Any way to exclude that other stuff, and only have it manage the core sip_devices and PJSIP stuff?
