I don't use SER but as far as inbound Provider->asterisk it 'just worked out 
of the box' without any problems for me. Making sure that

- authentication parameters are correct with sip.conf,
- you are registering with them fine
- registration line has a  /internalextension after it so it knows where to 
put the inbound call
- corresponding entry in extensions.conf relating to the above - internal 
extension above dialing a physical phone / group or whatever.
- asterisk ports are open / accessible from your provider
- codecs are compatible

also

- if you are making config changes to try and get things to work u r  better 
to stop and restart asterisk rather than 'sip reload'
- try both cvs and an older version, sometimes things break
- if you have multiple cards in the machine use nat=yes for the outbound 
provider to force asterisk to use the correct IP address in the sip 
messages.
- I would use asterisk for a test setup and once that is working  add SER to 
the equation.
- try a few different providers to make sure any problems are not provider 
specific.

NOTE these are notes from someone who CAN'T get SIP outbound calls to be 
placed correctly so take it with a bag of salt.... lol ... Good luck.
