Issues on Inbound Call V17

hitenbarchha · March 3, 2025, 9:43am

Hello

I am getting very strange problem on incoming calls. I have setup Trunks and Incoming Routes. Now incoming calls works well when I setup time condition as destination and fails saying Got SIP response 503 “Service Unavailable” back from 10.0.70.2:5060 when I use extension as destination. There is no issues with outgoing call.

Additional Info: I had migrated to V17 using migration tool.

Any help on this is highly appreciated.

Migrated Tool What you mean? You did Backup restore for FreePBX-17

Hi, Have you tried to use sngrep to see which side sending you 503 ?
Maybe you have a bad config or not upgraded modules.

Try to run sngrep 1st and send to us 503 screenshot and same time you can watch at Asterisk side CLI logs too.

hitenbarchha · March 3, 2025, 10:03am

Yes. That is right. Earlier I was using distro based on centos and now we have migrated to Debian based Distro.

Howdy! Welcome to the forums.

To clarify: your v17 setup works with both inbound and outbound calls, except when you have a time condition ?

hitenbarchha · March 4, 2025, 5:21am

There is a correction. Inbound call only works when there is time condition if I destination is extension, it doesn’t work. I shall post required logs and screenshots shortly.

You can make TimeContidion IF Destination is not existing or busy, call to redirect other Endpoint or Misc Destinations or soo… You have to play with your changes and with yours scenario.

SNGREP screenshot attached.

I don’t understand why call to ****2244 have jumped to ****2222

shahin · March 17, 2025, 10:33am

You have to dig this message, Same message sngrep showing to you.

hitenbarchha · March 17, 2025, 10:56am

It seems like configuration level issue than an infra level issue. Provider have confirmed that their infrastructure is working well and we are able to make outgoing call without any problems.

When I dial a number it jumps from CID to different DID and CDR also makes 3-4 entries. I don’t understand why call to ****2244 have jumped to ****2222

jcolp · March 17, 2025, 11:09am

Without a console log from Asterisk I can only guess, but it honestly looks like it’s looping back to the provider, back to you, back to the provider, back to you.

hitenbarchha · March 17, 2025, 11:21am

That is true but I don’t reason on why is that happening. I am also having backup setup of Freepbx 16 where everything was working well and I don’t see this observation on freepbx 16. Things that have changed is Freepbx 16 → 17 and Asterisk 18->20. Driver is same chan_sip.

jcolp · March 17, 2025, 11:40am

Providing an Asterisk log[1] would likely yield more insight.

You have somehow created a loop. You need to show actual setup of the Inbound Route and the Extension along with your Outbound Routes.

Provider = 10.0.xx.2
PBX = 10.0.xx.106

You will notice the incoming calls comes in and right after the PBX sends the 100 Trying to the provider for the incoming, the PBX then sends the call right back to the provider which then loops back into the system it looks like.

Every message in this output is either from 10.0.xx.2 or 10.0.xx.106. Never once is another device/endpoint involved in this call.

Here’s the first INVITE sent back to the provider after the initial 100 Trying is sent:

Note how the PBX is sending the call that should be for the extension back to the provider.

I believe this will be faulted in this version of Asterisk; it has been deprecated for a very long time.

Best option is to use chan_pjsip.

If using chan_sip, unless there is a specific reason for making it insecure with respect to source ports, the best solution is to use remotesecret, instead of secret, but if you want to use the old hack, it should be insecure=invite.

Given that phones won’t try to authenticate the PABX, this combination doesn’t make sense, as you are blocking all inbound requests, so will never challenge them for knowledge of the secret.

This doesn’t make sense with your deny everything setting, and is normally not the most secure option. Unless you really need type=user matching, you should use type=peer.,

I have migrated to pjsip and done some corrections on settings. Inbound and Outbound calls are working fine now.

Did you setup the provider side to send calls to port 5060?
