Solved Softphones not hanging up the incoming calls while ringing

alexm2017 · July 18, 2017, 8:37am

Dear all,

I have installed the last stable version of Freepbx 64bit.
The whole setup is working fine but i have an issue.

I have tested bot 3cx and xlite for this scenario.
When i am receiving a call but i don’t answer on my softphone, and i click close the call, it appears on softphone that the call has ended, and after a few seconds its ringing again until the call initiatiator is closing the call.

If i answer the call on my softphone, i can close it with no issue.

I don’t have any firewall in between the computer and pbx
I disabled firewall on windows computer.

I am using tcpdump on freepbx to trace packets.

Does anyone had this issue before.?

This is the sequence:

FREEPBX is receiving a call and sends an INVITE to pc with extension configured on softphone
softphone send: RINGING
I hangup from the softphone, i am sending Busy Here
FREEPBX it is saying ACK
Again FREEPBX it is sending again an INVITE
Again softphones is RINGING
Again i am closing the call from softphone with “busy here”
Again Freepbx is sending ACK
I am closing the call from mobile so it will not ring anymore in softphone.

I am seeing in the invite of the FREEPBX the following line:
Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE.
And i am sending “busy here” from softphone when i am hanging up. Maybe…FREEPBX does not know about

“SIP/2.0 486 Busy Here.” how do i add this message to freepbx to understand it?

???

Ok by mistake i don’t know why all extensions had follow me activated…with some weird config to call on the same extension like a loop.

So after disable follow me everything it is ok.

Thank you
