Calling from PRI

6 PRI lines are terminated on 3660 router, how i can initiate a call form these PRI lines to any ISDN/GSM mumber?

Is it possible ?

the logice is, data will be transfer from central site (PRI lines) to remote sites. there will be no efforts from remote sites for data transfer. the remote site may have an ISDN connection or GMS SIMcard with modem

Hi

AFAIK you can dial onto the ISDN lines in your remote locations from the central PRI but sure though about the GSM SIM Card with Modem setup..

Re: Calling from PRI

Hi Vinay,

It is very simple , hope you have configured loopback address. Make PRI. a member of this loop back address. ( use pool member cooomand. )

Create dialers for different locations, add a dialer string for every location in each corresponding dialer. Define interesting traffic using acces-list and use this access-list to trigger the corresponding dialer. Give static routes for all dialers. On the other end configure similar dialer with dialer caller command in it. so that it will accept calls only from Central location. Give IP address from same subnet that of loopback address.

Here is example

Assume you have a network 10.10.10.0 /24 at location A and ur central loaction is B. Dilaer 1 is configured for location A.

so route will be

ip route 10.10.10.0 255.255.255.0 dialer 1

This will route traffic to dialer 1 . which in trun trigger PRI for location A's ( using phone number.)

You can test which are the users are now connected on PRI by command

sh users . You can check which ISDN chanels are currently on by sh isdn act command.

But make sure that BRI at the other end is ok.

Use isdn test call command to trigger PRI line mannually. and test that call is getting complete.

Hope i have given you lots , hope it will help

Thanks
