[Serusers] SER + SIPSAK

[Aster]

All,

I saw some post regarding sipsak and ser together to do register with
other sip provider.
I searched as much as i can to get more info on how to do this
ser+sipsak and not any luck so far.
If anyone using these kind of setup, could you please share that. Or
is it doable to do register with other sip provider using SER. I am
only intersted in just the outbound leg.

TIA
