when configuring multiple SRST routers for a single site.

What is the ip-helper address in the gi int. Is it the pub address or the subscriber?

Can there be more that one ip-helper address considering that my customer had three backup sunscribers.?

The ip helper-address will ordinarily be require for DHCP relay, therefore if you have configured your Voice VLAN scope across both Publisher and Subscriber then you will need to specify both.

I think you maybe refering the TFTP Option 150 in the DHCP scope? If this is the case then you simply specify all three if you have TFTP enabled on them.

If you have configured a local DHCP scope on the gateway you can add multiple ip address as follows:-

ip dhcp pool Voice-LAN

option 150 ip

Hope this helps.
