Hi there,

Please can i have some help in understanding why i would get the below. (in telephony terms?):
1. "temp Unavailable"
2. "Request rejected"
3. "Check your external telephone lines"
4. "TRying to connect"
5. "Network failure"

Tx so much....

Hi,

here is my answers with some approximation:

1. "temp Unavailable" - the SIP server should have been unavailable(Quadro did not receive any answer)
2. "Request rejected" - the SIP server rejected the request by some reason
3. "Check your external telephone lines" - no activity on PSTN lines(like no line is connected)
4. "TRying to connect" - outgoing call was closed during Quadro retransmitting outgoing requests.
5. "Network failure" - packets could not get out of Quadro by some network fails reason(for example firewall blocking the destination address).

Hope this helps.
