             Summary: Issue related to Transfer of call to external number  : Constant poor audio and frequent drop of call
                 Key: ASTERISK-29327
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29327
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip, Channels/chan_sip/Interoperability, Channels/chan_sip/Transfers, PBX/pbx_config
    Affects Versions: 16.8.0
            Reporter: Prune
            Severity: Major


Architecture:
We are interconnected in SS7
Our "class 5" ISwitch translated into SIP
The traffic is sent to our Asterisk server.

We use:
- PJSIP channels
 - 711u

- The 711a and 711u codecs are used in the ISwitch.

We have no problem with incoming and outgoing calls to an external number.
Call forwarding to an external number works well;
But, any TRANSFER to an external number creates an audio problem and sometimes an interruption of the call.

1 / Audio problem when transferring to an external number:
- No sound at all after a few moments,
then the conversation is audible again.
- White noise / cracking

We noticed an audio problem with the transfer to a landline;
but, the transfer to the cell phone no problem noticed.

We don't have a lot of traffic because we are still testing the call manager so we don't think it's coming from bandwidth.

2 / Call stopping after some time after a transfer:

>From time to time we have the loss of the transferred call and the callback of the transferred customer.
Example: we transfer a call to an agent, the caller and the agent are both talking; then the call is terminated and returned to the call manager. The call manager should take the call back and transfer another time. The agent is not on the line after the call is disconnected.
The customer did not decide to hang up and was interrupted in the middle of the conversation.

Thanks for your precious help.
