I'm having the same problem but with ATA-connected analog phones. The ATAs are Grandstream GXW4008 with firmware v. 1.0.1.15. The "canreinvite" option in sip.conf doesn't change anything for me. Downgrading the GXW4008 solves this issue so this is obviously a firmware bug in my case. I had a vague report once of a user in another installation having this 1-second delay on call connection. That user had a Cisco phone but I don't remember which one. I suggest you check this with Cisco Support if you can.
