I am having trouble configuring FXS/FXO ports on a Cisco 3600 router used as a gateway with CCM 3.1.
I followed guidelines from cisco website,which is
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a008017825e.shtml
I used mgcp, and I get no dial tone on FXS ports.Also, i am unable to call to PSTN from my IP phones.
Can anyone please help me out with this????????

Can you throw your config up here? That would help a bunch, as this is a really generic item with many possible places to go wrong. Also, I can only speak for myself, but I haven't done work on a 3.1 system in literally years. Any plans to upgrade?
