call transfer doesn't work on SIP Phones
Hi Experts,
I installed CME (ISR 4321 IOS version 15.5), with 40 Phones 7821, 1 IP Phone 8841, another 8851, and 2 IP Conference 8831 using SIP Protocol
all of these SIP Phones work fine, but the call transfer doesn't work, I don't know if some config missing, you find below the sh run,
thank you for your help.

I.e. To transfer, the connection/call you want to transfer is placed on hold, while a new outgoing connection is initiated to the destination. When you hit transfer a second time, the inbound call is setup via your ... And linked to the outgoing call. At this time you gave two sip connections consume.
Can your phone/setup handle more than one call at a time. I.e. Can you place a call on hold, and initiate a new outgoing call?
If you are forwarding/transferring to an external destination, you have to make sure to configure the system to allow that.
Deals with allowing an external/incoming call from being sent back out.
