Dear All,
I’m using FreeSBC as a Sip Proxy between ITSP and Internal network. I have in the same network Cisco 2951 acting as Sip Proxy also, and I’m testing Freesbc to replace it.During the tests, we noticed that PDD in the FreeSBC is higher than Cisco. I tried to fix it, without success. Does anyone know what the problem may be?
I found the problem, and there isn´t in the FreeSBC. The problem was on softswitch side, that was not recognizing SIP 183 as alerting.
