To achieve what you described, create a SIP extension without password, and replace the Dial field under Device Options with SIP/hassan@voip.getemo.com.
So every time you need to reach that SIP URI, dial the extension number associated with it.
The string 00+|xx. is invalid, since you cannot dial a plus after 00 even with a mobile phone.
The string 00|xx. means match 00 and at least two digits, then discard 00 and pass every digit after the | to the trunk.
Likewise the string 00+0xx. means match one 0 and at least two digits and prepend 00 to it.
Sipura's dial plan is very flexible, but is also cumbersome if it becomes too long.
