Hi Guys,
I have a SIP provider who only accept registrations from users, so I have registered my kamailio Server with them using the uac module.
It is registered fine, and I can get inbound calls on the trunk.
My query is the best way to send outbound calls out via the registered sip gateway?
I would normally load balance using dispatcher if it was to IP authenticating providers, but as they are using registration, what would be best practice to send outbound calls via the registration which is establised with the uac module?
Is it just a question of doing it within the configuration file, as again they will look to auth requests as well with a 401/407 so I assume I can use uac_auth() for that.
Just wondering what other people have done if anything, is my other option is to register using a B2Bua on the same server, and leave kamailio just as a proxy.
Many thanks
Jon

Normally there is no correlation between REGISTERs (to tell an other server where to send incoming INVITEs) and outgoing INVITEs. So just do whatever you normally do and be prepared to respond to a challend (with auc_auth).
Hi Daniel,
Thanks for the response.
My problem appears to be kamailio proxying the 407 response to the originating SIP trunk, which I appreciate it will do as its a proxy.
I presume if I want to absorb the 407 and handle only on the kamailio proxy which is the last point to the SIP carrier, this is more B2BUA, as I would normally have FreeSWITCH/ASterisk registering with the outbound sip provider and proxy the request via kamailio, where as in this case I am registering direct from kamailio so making it a little more complex in terms of handling the 407.
