CCM and Gateway config

[GLHEC]

hello all, i am trying to get a 3725 with a fxs card working with ccm 3.3. i followed:

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a008009428e.shtml

and it works,,, kind of. i have everything configured on the ccm and it looks right, i have dn and the gw is registered. i have 2 pots phones and 3 voip phones. the voip phones can call the pots phone, but when i take a pots phone off hook i get a busy signal, so pots cant call voip. i am very new at this ccm so thanks in advance.

 

[lui3]

are the pots phones in the same call search space as the voip phones?

 

[GLHEC]

I think so, do I just check that ib the ccm?
thanks

 

[lui3]

yep

 

[GLHEC]

i checked and both the pots and the ip phones do not have a CSS set. they are "none". any other ideas? i am hoping this is something simple i have overlooked. but i did follow those docs concerning the fxs and ccm configs. anyone?

 

[GLHEC]

btw--

System image file is "flash:c3725-ipvoice-mz.123-7.T1.bin

again i want to state that when i pick up the pots phones, i get a busy signal. before i did the ccm route, i attempted just configuring the pots phone to call each other via dial peers on the router and it did work. so i really think it is some config issue. here is the config on the router:

try placing them in the same call search space as the phones you are trying to call. you can always change them back.

 

[GLHEC]

it didnt work. any other ideas?
thanks

That is pretty strange behavior...if the analog phone goes off hook you get a busy signal. It almost sounds like you might have some kind of PLAR configured in CCM. Are there any translation patterns in your CCM?

i had this happen to me in the lab. try adding the following command

ccm-manager xxxxx then add the ip address of the call manager.



show mgcp statistics and post

the gateway needs to have knowledge of the call manager.

when i enter "ccm-manager" these are the only options i see:

config-download
switchover-to-backup


i dont see any option for an ip address.
the gatway knows about the ccm from "mgcp call-agent 192.168.55.2" right?

thanks and i look forward to more ideas

 

[lui3]

yes it should do a debug of mgcp. i had to play around with it until it worked. i also had to make sure that the call manager was registering the gateway via domain name. i will look into my configurations and get back to you

I got it working. I had a prefix DN entered which broke things.
thanks everyone
