SIP Refer problem

Hi Guys,

I have problem at one of our customer side. When an operator received a call, and try to do a transfer (consult transfer) to a colleague, the colleague's phone ring one time and the call failed. The operator have to take back the call and give the full external number of the colleague to the caller.

After a reboot of the phone (unplugged/plugged) the transfer work fine !

I tried to find the cause in the CUCM traces but I need help.

Saw that Refer messages:

Hello,

It's not possible, logs come from a financial institution, and I need to remove all the full E164 number from the logs (to much work).

But thanks for your help by the way

Unless we see the full picture we cant tell whats going on..Sorry. Even if you open a TAC case, you will need to send the full logs
