Hello all:
Hello all:
I am trying first to Address a routing issue with our IVR Platform in regard to
sending calls through our ACME SBC.
Since all calls are serviced through this appliance what "SIP" remote IP should
we be sending the calls to?
If we send the calls directly to the SBC we get hung up at the 100 and no 200
okay coming back to us.
The Current solution in place is to call the remote sip ip which is the hammer
g5 10.205.53.4 which the SBC recognized as a valid IP in its address tables to
allow the call to proceed to the IVR platform. (in trying to simulate what
our hammer appliance was/is doing currently).
The following SIP ladder call flow is the request from the SIPp Load Generator
towards the Hammer G5 then on to the IVR platform, this example we are just
making a call to my desk phone.
|Time | 172.20.2.242 (<-our SIPp load generator) | 10.205.53.12
|
| | | 10.205.53.4(<-hammer remote IP) |

What I am trying to figure out is what the IP the SBC is not recognizing here
if we send the call directly to the SBC from sipp@172.20.2.242:5065?
Thanks
John
