Hi There,
Looking for some advice or perhaps even just a starting point with an issue we are having with our calls.
We are finding that when customers are calling into our service and staff place the calls on hold to transfer a call when they complete the transfer there is no audio at either end.
From some testing I have done a pattern I have noticed that when the staff member you are transferring the call to answers and you transfer the call within 1-5 seconds the majority of these work fine. However if the call is left on hold for 10/20/30 seconds or so and you transfer the call this is when the audio fails. The call still stays connected it doesn't disconnect or anything however there's no audio at either end.
The majority of our users are on Cisco Jabber and some sites are using Cisco 7841s and we can replicate the issue on both physical and softphones. The majority of our calls are coming into Hunt Groups.
The initial reports of this started when we migrated to SIP I am just wondering if anyone has experienced similar problems?
