----------------------------------------------

Hi Bala, attached in call.pcap and call.log traces of example call, parties involved:

- 78.47.214.44 Asterisk
- 78.47.214.45 SIP client - ext 201
- 78.47.214.46 SIP client - ext 202

if you email me at chris [at] wima [dot] co [dot] uk I can provide you login details to working test environment I used to capture PCAP trace attached, so you can explore the issue further yourself.

> Hi,
> When attended transfer to ExternalIVR is completed *after* ExternalIVR app starts no audio is sent to SIP client.
> To reproduce the bug:
> 1. Download example config which can be found here:
> https://github.com/level7systems/asterisk-cfg/tree/ExternalIVR-xfer
> 2. Register SIP client for ext 201 and ext 202.
> 3. Perform call scenario as below:
> a) 201 calls 202
> b) 202 performs attended transfer to ext 125 (ExternalIVR). 202 waits 10 seconds before completing the transfer
> c) when transfer is completed there is no audio sent to 201
> Note: if the same scenario is performed, however in step b) 202 waits only 3 seconds before completing the transfer audio is sent to 201 correctly. So it seems the issue doesn't occur if attended transfer is completed *before* ExternalIVR app starts and happens only if transfer completes when ExternalIVR app already started.
> Note 2: the same problem affects ver. 11.22.0 as well.
> Regards,
> Chris
