Sip unifier?

Does anybody know if there’s any service on the net that forwards (for ex.) 5 sip account, from different providers all, just in one sip account that lets you receive all the calls from all the providers?

ex:

(SIP 1–SIP2–SIP3–SIP4 ) -->=SIP5

and on SIP5 you receive all the calls from sip1,sip2,sip3 and sip4; and some how you can configure it for the outgoing call to work with some of them… lol

Thanks

Not exactly it’s function but you could try EasyPABX. This is basically a hosted PABX system but could (I believe) do what you are looking for.

very very easy

in * sip.conf set the contexts for accounts 1-4 to be the same

then do in extensions.conf

[all-accounts-go-here-context]
exten => _X.,1,Dial(SIP/account5)
