Hi ,
Following is my present setup
Provider -------->SIPSER based PBX------------>IP-Phone
the SIPSER bases PBX solution is a properitery solution and gives only limited web based access.
I plan to Use asterisk box as my primary PBX and use the existing SIPSER Box as a SIP Gateway.
Provider <-------->SIPSER<------------>Asterisk<-------->IP-Phone
I created a sip trunk from my asterisk box to the SIPSER .The Trunk got registered on the SIPSER .
However when I make the call using the SIP trunk I get a route busy message.The same is for Incomming calls
any ideas on what I might be missing
regards
Unni
