[cisco-voip] Problem with inbound calls to FXO interface

[Ortiz, Carlos]

It might be a bug as someone suggested, but since this is MGCP, the
calls are controlled by the Call Manager. Check the inbound Calling
Search Space of the port to verify you can reach the internal phones.  I
once has a situation where the phone would ring once then go no further
and it was the calling search space.

Subject: [cisco-voip] Problem with inbound calls to FXO interface

 

Greetings,

 

I am having a problem getting an FXO interface on a 1760 router to work
correctly. I am able to make outbound calls correctly, however when I
try to make and inbound call I can't get it to ring to the Attendant DN.
Following the initial configuration when I would dial into the Interface
it would ring once and then playback dial tone. I have a feeling that at
this point the gateway was possibly waiting to hear digits in-band to
know where to route the call to. However inputting digits at the dial
tone had no effect on getting the call to ring the extension. 

 

At the suggestion of someone else I tried using the "connection plar"
statement on the voice port and pointing it at the attendant DN number
in this case 6000. Using this statement did change the behavior of the
gateway when called; when I call now the line rings once and then goes
to a fast busy instead of a dial tone.

 

I was hoping someone might have some ideas on what I might be missing
here; this is my first time working with an Inbound FXO Gateway so I am
a bit unsure of where I might be going wrong. I have pasted the Gateway
config in-line below. 

 

Thanks in advance
