We are using Iristel for a trunk. The host that sends the SIP calls to our freepbx is iristel.net which resolves to 209.58.101.235 and 209.58.101.236
we tried both the following host=iristel.net
and
host=209.58.101.235&209.58.101.236
When Chan_Sip Peers shows the iristel trunk as 209.58.101.235 I get Log(“SIP/209.58.101.236-00000048”, "WARNING,“Rejecting unknown SIP connection from 209.58.101.236"”) in new stack which makes sense.
How can I get it to use both IP’s in the same trunk??? From the research that I have been doing host=209.58.101.235&209.58.101.236 should work.
Well I don’t experience with your provider however just looks like two separate sip servers to me. I would create a separate trunk in FreePBX for each with my provider.
It’s not a workaround - it is absolutely the correct way to solve the problem. Think about it - it is set up for host authentication and the only way for host authentication to work is for the host to be identified.
