Voice over PIX

Hi

I have one pix in my local LAN. so i have created one zone for servers, and second zone for some users and third zone for some other users. Now i have installed cisco call manger 4.1 and it works fine if phone and ccm are in same zone, but i want to put ccm in server zone while phones would be in different zones.

Can anybody help me out in this. My pix software ver is 6.2

Thanks and Regards

Re: Voice over PIX

You need to enable special commands for DHCP that it works (option 150 and 66).

example:

fixup protocol h323 h225 1720

fixup protocol h323 ras 1718-1719

fixup protocol rtsp 554

fixup protocol sip 5060

fixup protocol sip udp 5060

fixup protocol skinny 2000

fixup protocol tftp 69

dhcpd address a.b.c.11-a.b.c.99 voip

dhcpd dns DNSIP

dhcpd wins WinsIP

dhcpd lease 3000

dhcpd ping_timeout 750

dhcpd domain mydomain.com

dhcpd option 150 ip VoipRemoteGate11 VoipRemoteGate10

dhcpd option 66 ascii VoipRemoteGate11

dhcpd enable voip
