[Asterisk-Users] Problem with blind transfer and Polycom phones

[Kib Eki]

Hi,

we just set up an asterisk with 55 Polycom 500 IP phones.

The blind transfer does not work.

The way we try to blind transfer a call:
1. answer the call
2. press transfer
3. press blind softkey	-> the display shows "Blind transfer to:" and cursor is 
in the second line
4. enter the number	-> when we enter the second digit of the number the display 
jumps back to "Hold: <number>" view.

It is reproducible.

Attended transfer works.

Any help is welcome! :-))

Regards,
BK
