Hi Team,
I am using the 3CX version:15.5.13103.5 in Linux Debian installation.
The problem is when the user answer external inbound call and try to do attended transfer to the another user the call bounce back to the same person who initiated the transfer the external caller is with him.But the blind transfer works.
This flow sequence
1) An external call arrives (4429226XXXXX)
2) Ext:4002 picks up the phone and answer the call puts the external caller on hold
3) Ext:4002 calls the ext:4008 to check if user is free
4) Ext:4002 try to transfer the call to ext:4008
5)In mean time external caller(4429226XXXXX) hears the hold music
6)Call bounce back to the ext:4002
7)Call transfer fails and external caller(4429226XXXXX) is with ext:4002
We have 8 extension configured for the client all the 8 extension are Stun remote extension the phones used are yealink 5-T46G & 2-T48G all the phones are with latest firmware registered with 3cx system.
I have checked the following options in extension settings
1.[pbx deliver audio,support Re-Invites,Support 'Replaces' header] enabled for all the extensions,
2.Also allow multiple call options also enabled
3.All the extensions set to have own local SIP port and RTP ranges since we have provisioned it as [Direct
SIP -stun remote].
4.Firewall checks all passed
5.I have verified the ALLOWSOURCEASOUTBOUND parameter it is set to 1.
I have verified all the possible settings in the phones, extension and 3cx server parameters but could not find why the attended transfer calls fails.if any one has any answers that would be great.
