Remote Office with IP Telephony

I have a Central Office with a ISPBX that support IP Telephony. I would like to connect a Remote Office with two Cisco routers with a BRI interface. In the Remote Office I have 10 IP phones..... how can I configure the wo router to setup B channel only when I have traffic? If I use load-interval command to set the interval in what the router calculate the avarange bandwidth on the BRI interface I have the lower limit of 30 sec. Every IP call need 25kbps so if I have in the first 30 seconds 3 calls I have not enough band.

Is there any solution to my problem?

Tanks. Giovanni.

Re: Remote Office with IP Telephony

There is no solution that I know of to a problem that is bandwidth related -- except to increase the bandwidth.

Keep in mind that the load-interval command only changes the way the input and output rates are shown in the show interfaces command output.

I think the dialer load-threshold x command is probably what you are looking for.

Re: Remote Office with IP Telephony

I think there is a solution for small office environment called IP Telephony Service 2.0. Do a search on CCO for the term and see if it solve your problem. The old name was Keyswitch system in which a router can do call routing. Hope that help.
