Is it possible to port Cisco 2621 features to Cisco 2911?

Question

Telephony

The question is, there is such a network structure:

Router 2621 failed. It had 2 FastEthernet ports, one of which went to the ADSL modem, the second to the 3560 router on which Vlans were raised. config 2621 :

Is it possible to transfer its functions to CISCO 2911, it has two free GigabitEthernet ports
config 2911:

And if possible, how? I tried to set up one of the gigabyte ports, turned it on, but the data does not go, I can’t ping the gateway behind the adsl modem, the modem works in bridge mode.

Answer 1

It is not entirely clear from the question - do you need to completely replace 26xx with 29xx or add the functions of the deceased 26xx to the existing 29xx functions? And what do the pieces of iron do, purely VOIP, or do they also route the Internet?
