(Cause 20 - Subscriber absent) on Xlite

Hi guys, I have spent quite a while reading past questions about this and I just can’t figure it out. I’m new to Asterisk.

I’m running Asterisk 13.20.0 on raspbx (pid = 13975)

I can receive calls to my Xlite softphone just fine, but it won’t connect the outbound calls. I’m hoping this is just a simple configuration change, but whatever it is, it’s got me beat… It always returns ‘Unable to create channel of type ‘SIP’ (Cause 20 - Subscriber absent)’

Thanks in advance!

Can you post a full call log?

Are you looking for a chunk of the log file? Or a CDR? Or maybe I’m completely off in what you’re looking for?




Are you sure that you are using chan_sip and not chan_pjsip on the trunk and port you are connecting to your provider?

I see this

[2018-04-28 22:29:31] VERBOSE[28388][C-0000000d] app_dial.c: Everyone is busy/congested at this time (1:0/0/1)
[2018-04-28 22:29:31] VERBOSE[28388][C-0000000d] pbx.c: Executing [[email protected]:25] NoOp("PJSIP/200-0000000d", "Dial failed for some reason with DIALSTATUS = CHANUNAVAIL and HANGUPCAUSE = 20") in new stack

Perhaps check your outbound route and Trunk outgoing settings. Did it ever work?

I was using pjsip instead of sip - I’m trying to switch but this is what I’m getting now:

[2018-04-28 23:19:15] WARNING[4925] res_pjsip/pjsip_options.c: Unable to find an endpoint to qualify contact sip:[email protected]:57446;rinstance=7ca6eff11140b922. Deleting this contact [2018-04-28 23:21:12] WARNING[5227] res_pjsip_registrar.c: Endpoint 'anonymous' has no configured AORs

Do you suppose this is the issue?

Yes, you are still trying to use chan_pjsip, how have you configured the ports for chan_sip and chan_pjsip? And what port are your talking to your provider on?

This is all new very new to me so thank you for your patience.

I changed chan_pjsip and chan_sip to 5160 and restarted Asterisk - Now I’m getting:

[2018-04-28 20:12:06] ERROR[10304] chan_sip.c: Serious Network Trouble; __sip_xmit returns error for pkt data
[2018-04-28 20:12:06] NOTICE[10304] chan_sip.c: – Registration for ‘5244634972 @gw1.sip.us’ timed out, trying again (Attempt #2)

That is likely a firewall/router/network issue

When you switch the extension from chan_pjsip to chan_sip, make sure to click ‘Reset’ and ‘Apply’, and only then make changes related to the extension.
Don’t forget to restart your X-Lite so you force it to re-login.
