Received the following from Klaus a few weeks ago:

Does anybody have an example of how to use sipsak with openser. Does 
openser call sipsak, or is it the other way around?

    I am trying to get openser to register with username and password 
and forward a call to that server. This is for outbound sip termination 
to the PSTN. openser is a proxy thus basically openser can'T do that.

Now the good news. For registration at the termination provider you can 
use sipsak. For sending authentication credentials to the termination 
provider openser has the "uac" module. But be aware that this module 
does not always works as it does not increase the cseq when sending the 
INVITE with credentials (search the archive for details). E.g. the uac 
module wont work if the termination providers uses Asterisk (as 
Asterisk checks the cseq)
