[asterisk-users] oneway audio with asterisk behind cisco pix 506

[Wendell Hamilton]

Note also that if you point to the DNS name rather than the IP address of the asterisk server on the phones trying to register, you can set NAT=NO on the asterisk side and the sip FIXUP command on the PIX will handle everything correctly making this workaround unnecessary

Subject: [asterisk-users] oneway audio with asterisk behind cisco pix 506 





Hi, 



I have the Cisco PIX 506 firewall right in front of the asterisk and I am getting a one-way audio. I need your help/guidance to resolve this problem. I have the “fixups” disabled for SIP in the Cisco PIX 506. Any help rendered by you in this subject is greatly appreciated. I have been breaking my head trying to resolve this problem for more than one month. I have included the sip.conf and the extensions.conf below. 



[SIP.conf] 

; SIP Configuration example for Asterisk 

[general] 

context=incoming 

allowoverlap=no 

bindport=5060 

bindaddr=0.0.0.0 

localnet=192.168.5.0/255.255.255.0

[customer_ivr] 

include => local-extensions 

exten => s,1,Answer 

exten => s,n,Background(agnosco_intro) 

exten => s,n,WaitExten 



;Dial said extensions 

exten => 5,1,Dial(SIP/4028805362 at incoming,30) 



[incoming] 

exten => 4025901000,1,Goto(1000,1) 

exten => 1000,1,Goto(customer_ivr,s,1) 



Thanks
