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

RE: Problem with inbound calls to FXO interface [ In reply to ]
The connection plar 6000 won't work unless you have a voip dial-peer
that matches that number, or an ephone registered with that extension.



If you are trying to configure the gateway for SRST, you'll need to add
the following command:



application

global

service alternate default



I don't think that will solve your problem though. If not, I would
suggest removing the connection plar and dial-peers 10 and 11 (or add
the session mgcp command to them). There have been problems in the past
with MGCP where the default session dial-peers are matched when they
shouldn't be. The fact that your calls were being answered with dial
tone makes me think this is the problem.

RE: Problem with inbound calls to FXO interface [ In reply to ]
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.

Kris,

As soon as I removed the dial-peer per your instructions it worked
perfectly.

I am trying to upgrade an Emergency responder from 1.2(2) to 1.2(3a).
Release notes say minimum OS version 2000.2.6sr2 or later is required.
I installed 2000.2.7 and 2000.2.7sr7. CER upgrade fails on OS check
saying it did not detect 2000.2.6sr2 or later.?.

How do I install the CER upgrade ??? do I need to install 2000.2.6 and
2000.2.6sr2 on top of the 2000.2.7??

Looks like you are running into this issue:
CSCsa61886 - CER 1.2(3) upgrade may fail on OS version check
Symptom:

A. OS upgrade version 2000.2.7 and above. Without OS service release.
Upgrade to CER 1.2.3 may comeback with an error:
1."OS Image is less that 2000.2.6. This install is supported on
OS versions 2000.2.6.sr2 and
above.Aborting..."
B. OS upgrade version 2000.2.7 and above. With OS service release
2000.2.7sr1 and above.
Upgrade to CER 1.2.3 may comeback with an error:
1."Error in retrieving OS and JRE Versions from registry
keys.This install is supported only on
OS versions 2000.2.6sr2 and above.Aborting..."
and the installation will abort.

Conditions:
If OS upgrade version 2000.2.7 and above, with or without OS service
release 2000.2.7sr1 and higher is running and if the above any error is
received then use the workaround to upgrade to CER 1.2(3)

Workaround:
1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\System Info.
Export registry entry, Registry --> Export Registry, save it as
orginalReg.reg

2. Execute workaround.reg, given in the atttachment

3. Install CER 1.2.3

4. After CER 1.2.3 installation is over, execute workaround2.reg, given
in the atttachment

5. At the end execute orginalReg.reg

Please open a TAC case to receive the .reg files for the workaround.
