Try putting 011xxx.T ahead of 0.
When there's a conflict as you have here, most SIP phones have a SEND softkey similar to a cell phone, or the # key will work on FXS analog ports. You'll have a similar conflict between 6xx extensions and 7-digit local calls starting with 6.
Alternatively, define 00 as the local operator and add it to the dialplan.
Sorry I did not get back. I did check ordering. It seemed like the template got stuck I refreshed and rebooted phones. Has been fine ever since.
