[Nitesh Divecha]

Hello All,

My Asterisk is registered with one of the VoIP Carrier and the SIP proxy
they use is PartySIP 0.5.5. I can receive inbound calls on my DID numbers,
but when I try to make call out I get error message: -

Got SIP response 482 "Loop Detected" back from XXX.XXX.XXX.XXX

This is my sip.conf: -

port=7060
nat=yes
host=x.x.x.x
fromuser=<inboundDID>
