Brilliant...had no idea I had that option in GV. Funny thing is, I was trying to use my cell as a forwarding number on TWO GV numbers (had it working before I changed the cell #, then I couldn't get it to do the work/home dual forwarding thing anymore). It works fine on one GV#1, but couldn't get it to verify on GV #2 despite trying everything.
Strange...when I followed the instructions to set it up as a temporary forwarding #, GV recording said it already WAS a permanent forwarding number...very odd, because the GV website says it's not verified and when I tested it earlier my cell wouldn't ring, so there's a glitch somewhere...back to your suggestion...
I deleted it as a "non-verified forwarding number (??) from GV #2 and followed these steps and it worked perfectly. Testing confirmed it, slight 4-5 second lag between home line and cell line ringing...passed through caller ID data from originating number too, not my home phone, so I can still see WHO is calling when line is forwarded!!
Ideally, it would have been nice to have it permanently associated to GV #2, but this temporary forwarding option works just as well since I'd have to go into GV and activate/deactivate it to forward calls to my cell anyway.
Any idea if there is a limit on how long i can leave the temp number in place?
