After looking at your iax.conf and extensions.conf I believe you are 
under the misconception that if you 'register' to a provider, then you 
can send and receive calls.   The fact is that you 'register' to receive 
calls, but you must define a trunk in order to Dial Out.  Your iax.conf 
[88821268] entry is not a trunk as you have not defined a host.  That is 
why you get "cause 3 - No route to destination".  Asterisk does not have 
any host defined in order to route that call.  You need to talk to your 
provider for instructions on how to setup the trunk.
