PIX and softphone on the outside using SIP

satoshi.takano · ‎07-11-2007

Hi,

I have a SIP softphone talking to an IP PBX through a PIX.

I can register with the PBX with the extension, but I have no voice either way.

I have;

no fixup protocol sip udp 5060

no fixup protocol sip 5060

Otherwise, I cannot register with the PBX.

I have static (inside,outside) interface <inside IP> netmask 255.255.255.255 0 0

access-list inbound permit udp any any eq 5060

access-list inbound permit udp any any range 10000-20000

Any ideas?

Fixup protcol sip should be enabled:

There are several bugs with this, make sure you have the latest version of PIX software.

Hope this helps
