5 sec delay with ring group Freepbx 17 Asterisk 20

When I route straight to one extension, the delay is not noticeable. My ring group has 10 extensions to ring simultaneously. Any extension picks up with the 5 sec delay. I didn’t have this issue with Freepbx 15 Asterisk 16

I did have a similar issue a long time ago (+5 years). It was caused by the fax detection in the inbound route when the ring group was the first destination.

It’s not clear what you mean by “delay”. Does this happen AFTER the call is answered by a member of the ring group? What type of phones? What type of trunks? If you isolate a call from the asterisk full log, you can see from the time stamps where delay is being injected in the process.

I already switched back to Freepbx 15 since I don’t know the solution
Thank you for your feedback. I’ll check the log when I get a chance to retest to see if the fax is in the way

Yes. When an extension picks up the inbound call we can’t hear the caller until 5 seconds later. We have Sangoma phones 505 and 705 using pjsip. When I get a chance to retest I’ll post the log. Thanks
