My test system is an old Ultra-5 with only a 270MHz UltraSparcII CPU and it doesn’t seem to be handling Asterisk very well.
The system seems to cope with one or two calls outbound from my LAN, and the IVR can handle incoming calls via SIP, but when I try to forward an incoming WAN SIP call to an outbound WAN IAX call I get dropped calls. (The messages file shows SIP unreachable without 3000-4000ms pings when the call is dropped, and then drops back down to about 1400ms when it reconnects)
I’ve read about SIP re-invites and I’m wondering if I connect to both inbound and outbound ITSP using SIP can I offload the bandwidth to the ITSP’s after I’ve connected the channels?
Or does a re-invite require the inbound ITSP to know my username password at the outbound ITSP, making this impossible?
Can it be done another way? or should I go out and buy another PC?
