Hello
I am currently trying to use sipp 3.1 (windows) to test on a functionnal * box, running 1.4.24.1
I am using the default client scenario to call an ivr that plainly plays music, until a party hangs up.
When I am running 1 call, 1 simultaneous, everything is fine. When I run 2 calls, 1 simultaneous, eg, 1 after the other, it fails with a message on the * box ’ chan_sip.c:1976 retrans_pkt: Maximum retries exceeded on transmission sippuac for seqno 1 (Critical Response) and a message received by the client: Status 503: server error
here is the cmd line from the client:
sipp -cid_str sippuac -s 123 -d 5000 -sn uac 192.168.1.15:5070 -l 1 -m 1
Of course, if i try many simultaneous calls, it fails -
any ideas as to why ? or alternatively, scenarios & cmd line that work would be appreciated !
thanks for the help,
J.
