[Asterisk-Users] problem with hang up with TDM31B

[makevuy]

Hy,

I'm working with asterisk 1.2.4 and zaptel 1.2.4
With these version an the options in zapata.conf:

answeronpolarityswitch=yes
hanguponpolarityswitch=yes

I don't detect polarityswitch. When asterisk reloads I see in CLI:

May 10 00:44:27 WARNING[14639]: chan_zap.c:10876 setup_zap: Ignoring
answeronpolarityswitch
May 10 00:44:27 WARNING[14639]: chan_zap.c:10876 setup_zap: Ignoring

What happen??, Why don't detect hanguponpolarityswitch??

Thaks for all and regards.
