I'm sending an sms message like this over esl (telnet, java client, various methods all yield the same results)(numbers are all dummies): api chat sip|13215555555@6.50.120.201|internal/2395555555@6.50.120.200|test message This works fine with valid numbers. If I put in an invalid number somewhere I may see something like this in the sip trace indicating a problem: U +0.745829 6.50.120.200:5060 -> 6.50.120.201:5060 SIP/2.0 484 Address Incomplete. ... ...however over the esl socket I get the same response event no matter what, just "sent". Also, when I bind to the esl port and attempt to spit out every message possible (no filters), we see most of what comes through a sip trace, but again this bad result sip packet seems not to generate an esl event. Is there a way over esl to probe raw sip messages so that we can test for such a packet manually, or some other way of seeking the final async result? Thanks in advance!
