[Asterisk-Users] Cisco PIX and Asterisk

[Craig Waddington]

I cannot get incoming calls to sip phones behind a PIX to work, outgoing
is fine.

 

Asterisk (Public IP) --> Internet --> PIX (NAT) --> Sip Phones

 

I have tried no fixup protocol sip, I have punched a hole in the Pix
allowing anything from the Asterisk box into the network, still no
incoming.

 

I have done all the Wiki suggests in regarding to NAT.

 

Is their a trick getting the incoming to work?

 

Has anyone managed to get this to work or am I wasting my time on this?

 

Ta.
