[SR-Users] Stress Testing

[Daniel-Constantin Mierla]

Hello,

if the timeout is sent back by kamailio, then it tried to forward the
request but the next hop didn't reply. The next hop may be over capacity
or, if the next hop is not responding fast, be sure you have adequate
values for tm timeout parameters.

Cheers,
Daniel
