I am using the FreePBX Distro, I am at 1.810.210.57-1. I have multiple service providers. I am getting intermittant congestion with one of my carriers and looked in my Asterisk Log and see that this seems to be the relevant line:
[2012-05-29 13:55:35] VERBOSE chan_sip.c: – Got SIP response 503 “Service Unavailable” back from 188.8.131.52:5060
I called my service provider and they want a tcpip dump, and I say I do not understand how to do that, and they act as though I ought to know and as if it is obvious. So my question is
- Is it possible that the problem is on my end or am I simply getting congestion from my SIP provider?
- How can I give them what they want, (a tcp IP dump)?
