[asterisk-users] clever ways to "share" an extension between sip and fxs

[Jeremy Kister]

Using Asterisk 1.6.1.9, I'm looking for a way to "share an extension" 
between a SIP phone (Cisco 7940) and a SLT on a FXS port of a Cisco 1760 
(via sip) -- at any given time I want to be able to pick up either phone 
and it should be "bridged" to the other - just like having two SLTs on the 
same copper pair.

The goal is to have a cheap cordless telephone sit right next to a SIP 
phone and have technology-ignorant folk use the SIP phone as their primary 
phone and pick up the cordless when they are on a call and want to roam. 
Asking these people to transfer to 700, then wait to hear what extension 
the call is parked on, then dial that extension on their other phone is too 
much to ask :D

I've been thinking about having each on a separate extension and both 
auto-joining a meetme bridge when going off-hook, but it seems rather 
infeasible and eliminates features like call parking/transferring for those 
who would use it.

I know that I'm not looking for Dial(SIP/x&SIP/y) - as documented, this 
handles nothing like what I'm looking for.

Ideas?
