I’m having an issue that I’m really struggling with.
I have calls that won’t transfer on a some occasions. I am using Polycom phones models IP450 & vvx300 & vvx310. As well it will happen with Zoiper pro, ver 3 softphones, (basically every device I have)
In features.conf I have the attended transfer as #6.
So on calls that don’t work when they press #6 or use the transfer button they caller never gets turned over to moh, and they here the digits press. Its like on these calls the dtmf is not being handled correctly. The agents are transferring calls to other queues or local destinations. On some occasions if they park the call, than retrieve it they can then do the transfer as well.
Its not on any particular did, or inbound line. but it is absolutely a problem for me. I am running an older version of asterisk 11.25.1 and plan to update to ver 16 in the next month but takes some time to get through the change processes.
