Which IMEI number are they asking for, the number from the Fido phone or the Speakout phone?

I just ported a Telus payasyougo number to SO. Service was fantastic!! Took 3 hours!!

I called Speakout at 1-866-310-1023 at 10 am Vancouver time. The operator asked for my Telus number, my Speakout number, telus account number (which I have as I was using monthly topup automatically with credit card), my telus PIN or voicemail passcode, and the IMEI or ESN number. As my phone is an old Audiovox, I removed the battery and found 3 numbers on the phone. None of them said IMEI or ESN so I was instructed to call Telus to determine which one it was. It was the 11-digit number which started with 09… I was told that it would take 1-3 business days. They also asked for an alternate phone number in case of a problem. I supplied my landline number. At 1pm, 3 hours later, I got a message on the SO phone that the number had been successfully ported over. No one called the telus phone to verify as I guess that I had supplied the correct passcode and account to verify that I owned the phone. Great service from SO!!
