[cisco-voip] WMI, one way audio and more issues behind PIX

[Curt Shaffer]

IOS: 6.2.2

fixup protocl sip 5060 is in the config

 

PROBLEMS:  

 

1 - After placing a call on hold...when I pick it up... usually the party I
called can not hear me, but I can hear them.    Sometimes placing them back
on hold will resolve the issue, sometimes not.

 

2 - MWI Lights on phones do not work behind the PIX firewall.  What do I
need to do to make this work?  It works behind d-links, netgears, and when
on the wide open Internet.

 

3 - When placing a call from any IP phone or ATA behind the PIX firewall,
the rest of the network seems to go "unavailable".    When I stop the call
the firewall starts passing other traffic again.

 

Thanks. If you need more information please ask.

 

Curt
