SIP Transfer on CME

[Christian Semmler]

Hello,

I'm not able to transfer a call from a SIP phone to another phone.For testing I use the Eyebeam Client, but I recognized the problem with other SIP devices too(SPAxxx).

I set up a light configuration in the lab with two SCCP phones and one SIP phone. Trying to transfer a call from the SCCP->SIP phone to the other SCCP phone. But everytime I'm getting a busy signal and all calls are dropped.

If I initiate the two calls from the SIP phone and connect the this two calls everything is fine, conferencing with all three, too.

Hi,

i usually do this. After the first call is connected I put the first call on hold and start the 2nd call. Then I press the xfer button on x-lite/eyebeam(which result in holding the 2nd call) and after that I press the line with which I want connect the call.

This problem occurs as I tried to transfer with a SPA SIP Phone on my UC500, for better testing I moved to the Softphone SIP Clients. I already simulated this problem with a 2811 and there occurs the same problem in a complety new lab without any other configuration or endpoint.

The mysterious thing is that a blind-transfer works.

regards

Christian
