Can a PBX be used with a Cisco 3640 vro?

I have a Cisco 3640 router with FXS, FX0, and E/M voice cards. Can I use a PBX (dedicated group switch) with this router?

Can you provide an example to illustrate how to call different Cisco 2612 routers in other locations through the PBX vswitch on the MPLS network?

First, there is no difference in MPLS. It is only an IP transmission network. Your 3640 router can be used together with the PBX. FXO can help you connect to a PSTN or a PBX. FXS allows you to connect to basic phone devices. E & M allows the connection of the PBX trunk.

The simple settings are as follows:

Phone (1234) --- Gateway_router1... IP Network .... Gateway_router2 --- telephone (5678)

Assume that router 1 (router1) uses port 1/0, router 2 (router2) uses Port 1/0/1, and the decoder is g711. The Wan IP address of vro1 1 is 10.2.3.4. The Wan IP address of vro2 2 is 10.5.6.7. These IP addresses may be the IP addresses of the edge routers of your service provider connected to the MPLS network. The two vrouters are configured as follows. Check whether the network is used.
