Hi guys, i'm trying to accept calls from a vocal system on my proxy server, and forward this call to my dial plan.

Well done, I can see the incoming packets on ser sip proxy, but ngrep show messages like this:

SIP/2.0 400 Bad Request - 'Invalid IP Address'

And the call are finished on UA with 'fast busy'.

What I can do? Does this problem are on my se.cfg or in vocal side, or maibe in my routers (pstn) side?

Regards.
