[SR-Users] two way routing

[Jean Cérien]

Thanks, I went for the permission + dispatcher, and so far it looks good.

One last thing.... I need the kamailio server to explicitly register to a
provider. Googling the archive, I could only find an old reference to use
sipsak. Does that mean that sipsak (or any other sip crafting tool like
sipsak) should send a register request to Kamailio, which in turn will
forward it to the voip provider ?
