Re: UC500 remote branch office

Hi

I have one UC 500 with 48 users in site A and in site B I have a cisco 877W and spa9000 for IP telephony; (only 12 users)

I want to communicate both sites with IP telephony and I was thinking with vpn tunnel is the best option for de Site A call to Site B reading.

(Maybe if I haven't fixed IP address in site A and B, I Cam use some DyNDNS service?)

for example:

Site A:

dial-peer voice (extention_in_siteA)

destination-pattern (extention_in_siteB)

session target ipv4:(IP_in_SiteB)

Site B:

dial-peer voice (extention_in_siteB)

destination-pattern (extention_in_siteA)

session target ipv4:(IP_in_SiteA)

somebody Can give any clue.......

I hope that you can help me

thanks a lot of

I would highly recommend that you create a VPN tunnel between the two sites and apply QOS for voice on a per tunnel.

Then yes you could add H.323/SIP dial peers to each system and make calls between the two.

Example:

First Site, Extension Range 100-199

voice service voip

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

supplementary-service h450.12

sip

no update-callerid

!

voice class h323 1

h225 timeout tcp establish 3

!

dial-peer voice 1 voip

preference 1

destination-pattern 2..

voice-class h323 1

session target ipv4:192.168.20.1

dtmf-relay h245-alphanumeric

ip qos dscp cs5 media

!

Second Site, Extension Range 200-299
