Hi,
I'm having my first experience with VoIP, I configured a Cisco Call Manager 11 and a Cube (Cisco 2901 IOS 15).
After some days of apparently good job, the outgoing calls can't works fine no more but incoming calls from PSTN work.
My debug ccsip result is "SIP/2.0 404 Not Found" after INVITE and Trying.
After a thshooting I was amazing for speed test result, download was 10Mbps and up 0,7Mbps.
What warries me is not the bandwidht, but the availability of upload, I mean my upload is not available immediately but after 5 seconds about.
My ITSP is Eutelia and internet provider is a VDSL of CloudItalia.
As soon as i re-configure the sip-ua section, the call work but after some seconds fail again.
The Cube appears correctly registered with provider.
If I route to another ITSP the calls seem work fine.
Do you think the issue could depends on upload availability?
Thanks in advance
