POTS (FXO) Translation to an Internal Extension?

Christopher Baker · ‎02-12-2009

I have a POTS line on an FXO port (0/1/0) and want to have inbound calls to that number ring on ext 360. I will eventually have a PRI as well. In the end all calls will ring on the operator extension (testing using 360) ... company is old fashion, no AA.

I know I can "tie" the FXO to the phone via a "plar" to 360 (had it running that way), but I wanted to set things up like I believe I will have to for the PRI with DIDs getting installed in a few weeks. Therefore, I wanted to use "voice translation-profiles" for mapping inbound calls to the FXO (in prep for the new PRI) to the operator (x-360).

FYI - Since the POTS does not have DID, the "called" number is blank (aka - OriginalCalledNumber in the "show" output).

So I put in the config:

voice translation-rule 200

rule 1 /^$.......$$/ /8\1/

rule 2 /^$..........$$/ /8\1/

!

voice translation-rule 210

rule 1 /.*/ /360/

!

voice translation-profile Redirect-To-Operator

translate called 210

voice-port 0/1/0

When I call in, it picks up, then disconnects me without ringing the IP phone. If I look at the debug and show commands, I see it translates correctly (show call leg history):

It appears that the called number gets changed to 360. But 360 doesn't ring (I can ring 360 internally and call out on 360 fine). What am I doing wrong?

FYI - I see it matching the incoming dial-peer of:

Help?

Hi Chris,

I think this is an artifact of the way that connection plar works on FXO ports. It appears that the call-control API (CCAPI) does not kick the call off right, because translating an incoming called number of "" is different than a plar statement. This can be highlighted by the fact that there is both a 'connection plar' and 'connection plar opx' which are two different call routing processes. The default behavior if there isn't a connection plar statement is to play dial tone for two-stage dialing, and it appears that the translation pattern is interfering with that.

Your translation pattern looks fine, and this should work when you have your PRI installed.

I generally prefer to put my "translation-profile incoming Redirect-To-Operator" statement under the dial peer, because I normally don't look for call routing statements under the voice port. You may try putting this on dial peer 10 and see if you have different results.

Hope this clarifies a bit.

Having the translation profile on the matching dial-peer is how I had it originally, but that did not work.

Here is what happened...

1) moved translation from voice port to dial-peer.

voice-port 0/1/0

description Rockford, POTS 1, E911 Backup 1

caller-id enable

!

dial-peer voice 10 pots

description Incoming POTS-1

translation-profile incoming Redirect-To-Operator

incoming called-number .*

port 0/1/0

!

2) Made call in, monitoring the dial-peer (confirm match to dial-peer I thought it would and the one I applied translation to):

r1-rtr-voip#

Feb 13 15:38:41.389: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:

Calling Number=7083499940, Called Number=, Voice-Interface=0x47D551BC,

Timeout=TRUE, Peer Encap Type=ENCAP_VOICE, Peer Search Type=PEER_TYPE_VOICE,

Peer Info Type=DIALPEER_INFO_SPEECH

Feb 13 15:38:41.389: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:

Result=Success(0) after DP_MATCH_PORT; Incoming Dial-peer=10

r1-rtr-voip#

4) Router picked up, and then dropped call. Looking at the call leg history ...

4) So the translation pattern did not work. I just don't get it.

Are you saying this won't work this way at all with this setup (route FXO via translation pattern)?

Could it be a bug (I am using the latest CME running on "(C2800NM-SPSERVICESK9-M), 12.4(22)T / CME 7.0(1)". Should I be running something else?

Does anyone have some example configs of translation profiles and PRI's that I could model mine after?

paolo bevilacqua · ‎02-13-2009

Hi, try

rule 1 // /360/

Christopher Baker · ‎02-13-2009

No that did not make a difference. Still matched the 10 dial-peer and still did not translate.

Christopher Baker · ‎02-13-2009

The only way so far I can get this to work is:

1) Setup a "intermediate" dial-peer with the translation to the operator on it:

!

dial-peer voice 2300 pots

description Intermediate Dial-Peer to Operator

translation-profile incoming Redirect-To-Operator

destination-pattern 2300

!

2) Plar to the intermediate dial-peer:

!

voice-port 0/1/0

connection plar 2300

caller-id enable

!

This seems to work and lets me use translation patterns on the incoming and outgoing numbers prior to presentation to the IP phone.

I just don't understand why the other why doesn't work still. I guess I will ask for other examples of a PRI config to see what I need to do when that arrives.

Nicholas Matthews · ‎02-13-2009

The thing that needs to be understood about the call flow is that connection plar is much more than a translation. By having that command under the voice port, it changes the way to port acts with other parts of software. Doing a simple translation on the calling number is not the same thing, and I would not have any expectation for this to work.

This would not be a bug, because it's fairly flagrant mis-configuration.
