Unable to make a call through gateway

[lexiainfo]

Hi

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

Configuration memory.

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.

=========================================

Thanks

I fixed my initial problem with "mgcp sdp simple". I have other issues now, but will go through them in my own way.

I must compain about the lack of sample configurations just for basic connectivity not just in IP phones but in all Cisco.

I know I sound like an old person, but the Cisco site used to be great for initial configuration guides. Now it has all this obscure stuff that only one Cisco customer will use and other engineers will curse because they're in the way of basic information.

The recommended MGCP configuration with CallManager is to let the CallManager provide the gateway configuration from it's TFTP server. To do this add the following two commands:

ccm-manager config server 192.168.0.111

ccm-manager config

This is assuming that your TFTP server is 192.168.0.111.

More info regarding this can be found here:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vvfax_c/callc_c/ccm_c/intcnf1.htm#wp1068339

You will also need to remove the 4 MGCP dial peers you configured. CallManager will do this automatically. After you have done this Reset the gateway from CCMAdmin. After a short period of time you should then see the 4 dial peers CCM creates. If you don't see them try the following to see if they show up:

conf t

no mgcp

mgcp

Once this is working then you can try your test calls. If they don't work provide us with "debug mgcp packet". Provide the call flow info such as inbound, outbound, what ou experienced, etc.

I am having the same exact problems with the same setup.

The ccm-manager config server statements I don't believe run on 12.2 IOS, this is what is run on the 2620 router I am using as a gateway...

Any other suggestions? Does anyone have a working MGCP config with FXO ports they could post?

With my config, when the external number receives a call it will ring through to the DN of the attendant. But, I receive no audio on either side. About 20-30 seconds later the call disconnects. After this, anytime you call the external number you receive a fast busy until you shudtown/reload the voice interfaces...

Thanks in advance for any help!
