Hi,
I'm running a call load to an S/BC-->IMS Server. The S/BC times out the
Registry after 30 minutes. I can run a load for 30 minutes only. As a
workaround, I added the following logic and I'm running into other
issues.
<REGISTER all UE's> -> Separate SIPp instance
Call Processing:
Step1: INVITE -->
180Ringing <--
200OK(INV) <--
ACK -->
BYE -->
200OK(BYE) <--
ACK -->
<Small % of the UE's ReRegister; the rest goes to step 1>
REGISTER -->
401 <--
REG-Chlng -->
200OK(REG) <--
Then go back to the First step (Sending out Invite).
The Data file contains 500 origs and 500 term UE's.
The problem I see is that after completing the first 500 calls
successfully , the first UE gets a 503 error. From Call traces on SIPp,
I see that SIPp tries to send another INVITE after the call is
established.
Any ideas?
