I am using the following to make calls
1. Cisco 2620 Router.
[X.25 software, Version 3.0.0.
1 FastEthernet/IEEE 802.3 interface(s)
1 Serial network interface(s)
4 Voice FXO interface(s
32K bytes of non-volatile
16384K bytes of processor board
System flash (Read/Write)
2. Cisco IP Phone 7940.
3. Cisco Call Manager 4.1.2
4. Currently i have only one pstn line
Cisco 2620 is successfully registered with CCM please see attached.
So what should i do to make a call from the 7940 ip phone which is registered to the CCM.
I have followed the instruction http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a008017825e.shtml#task14x but unable to make a call.
Please note: PSTN line is going into cisco router directly from the wall socket.
