Is this the right format for a SRST dial-peer for international calling? It should match 011 and any number of digits then prefix the 011 on those digits correct? Because a dial-peer does not send matched digits? Thanks
dial-peer voice 803 pots
If this is your entire configuration:
dial-peer voice 1 pots
On a pots dial peer, any number that is explicitly matched is automatically dropped. By adding parenthesis or in Paolo's example brackets, they are no longer 'explicitly' matched because we're tricking IOS. These numbers are now kept in the stream.
All three examples should work. Your example has 8011T, with a prefix of 011, which should do the same thing.
