[SR-Users] "ACK not received"

Alex,

If I contact the calling UA 91.121.81.212 and give him my server ip
address and ask him to send me an ACK, he shouldn't have any problems
fulfilling my request? Since I am just testing, is this the best
approach when contacting another provider or is there another formal
way to do it?

Thanks,
