I would like to get some clarification on what I should expect in the
following situation.
Suppose I make a SIP call to a SIP client who has not logged in,
what should be the expected behaviour?
In my lab, I have 3 systems
- PC (linux server running asterisk)
- MAC with xten xlite sip phone
- PC with xten xlite sip phone
when all the sip phone registered with asterisk, everything works
fine. I can call any of the sip phone without problem.
Now, when the PC sip phone is NOT logged in, and when I call from
the MAC to the PC, I get the following in asterisk console:
*CLI>
– Executing Dial(“SIP/phantom-b717”, “SIP/homepc|15|t”) in new stack
Sep 10 21:16:24 NOTICE[7729]: app_dial.c:1091 dial_exec_full: Unable to create channel of type ‘SIP’ (cause 3 - No route to destination)
== Everyone is busy/congested at this time (1:0/0/1)
== Auto fallthrough, channel ‘SIP/phantom-b717’ status is ‘CHANUNAVAIL’
And, the MAC xten siphone says
"Call failed: 503 Service Unavailable"
Is this normal?
Thanks
