UC500 Outgoing line selection

Unanswered Question
Jan 9th, 2009

Hello,

How do we configure the UC500 to choose the outgoing POTS voice line?  i.e, Calls should always go out thru voice port 0/1/0 first and if its busy rollover to 0/1/1 etc.  I have a 8 FXO port UC500.

I beleive there is a preference command on the dial-peers but then its defined for each outgoing port.  Any ideas?

I have this problem too.

Hi Jibu,

Today this functionality is supported outside of CCA using CLI. You can configure the dial-peer, with the FXO port that you want to always use, with a higher preference and let the other dial-peers have a lower preference. For example:

In the configuration below, CCA sets all the dial-peers for FXO ports with preference 5:

!

dial-peer voice 54 pots
corlist outgoing call-local
description ** FXO pots dial-peer **
translation-profile outgoing CALLER_ID_TRANSLATION_PROFILE
preference 5
destination-pattern 9[2-9]......
port 0/1/0
forward-digits 7
no sip-register

!

dial-peer voice 60 pots
corlist outgoing call-local
description ** FXO pots dial-peer **
translation-profile outgoing CALLER_ID_TRANSLATION_PROFILE
preference 5
destination-pattern 9[2-9]......
port 0/1/1
forward-digits 7
no sip-register

You can modify this configuration (and any other dial-peer configuration for port 0/1/0) and set the preference at 4. Leave the other dial-peers at the same lower preference.

!

dial-peer voice 54 pots
corlist outgoing call-local
description ** FXO pots dial-peer **
translation-profile outgoing CALLER_ID_TRANSLATION_PROFILE
preference 4
destination-pattern 9[2-9]......
port 0/1/0
forward-digits 7
no sip-register

!

dial-peer voice 60 pots
corlist outgoing call-local
description ** FXO pots dial-peer **
translation-profile outgoing CALLER_ID_TRANSLATION_PROFILE
preference 5
destination-pattern 9[2-9]......
port 0/1/1
forward-digits 7
no sip-register

If you need to define a decreasing order of preferences, then with 8 ports, you can start with preference 1 and go on lowering the preferences for the other dial-peers.

HTH,

This is quite helpful, but I noticed in IOS that there are multiple dial-peer entries for each FXO port, mostly differentiating beween the corlist settings - I thought I'd ask for the clarification that the preference level should be set to all the dial-peers for the port, unless needed otherwise.

Regards,

Luis

The links were very helpful and I had configured it.  Its has to be done for all dial peers, 4 or so per FXO port.

You'll need to remove this port from that trunk group and reference the port itself in POTS dialpeers.  Then set the preference of those dialpeers that point to this port to be lower.  For more information, follow this link:   https://www.myciscocommunity.com/docs/DOC-1416#What_is_the_predetermined_outbound_call_routing_per_fxo_port_now_and_can_you_change_this_so_that_when_dialing_out_a_particular_fxo_port_is_used_first

Bob,

You can configure your outbound trunks on the configure->telephony->dial plan->outgoing page under the PSTN trunk groups tab.

Skyler Spence Thu, 05/28/2009 - 11:03

When you highlight the group on this tab, you should see a modify option near the bottom of the page.  Can you send me a screenshot if you don't see this?

Skyler,

I found it, this app is not good on a laptop as I had to scroll within my scroll window to see the modify (Duh). I was able to take FXO 0/1/0 out of the ALL_FXO trunk group and create a new Trunk Group (but watch the name as it did not take mine the first time). Then I went into the outgoing dialplan and modifed all PSTN entries to select MAIN_FXO as preference 1, and ALL_FXO as preference 5, and SIP as preference 6 (where I had both PSTN and SIP).

This really saved me on the cutting and pasting for so many entries!

Thanks very much and keep up the good GUI development!!!!

Bob

I too had trouble finding the modify button for outgoing dial plan :)

Some particular I noticed when using a sequential dial plan, does the highest preference FXO line need to be on the bottom?  I'm excluding one truck from the list (for a CO line) but in order to ring out the way I want, I had to sequence the other FXO lines in reverse order!

Sorry Skyler this does NOT work, in CCA 2.0 it showns me two trunk groups one with the FXO 0/1/0 port in it, and I setup the PSTN outbound dailplan to use this first (preference 2) then the ALL_FXO trunk group.

CCA took the config, I saved it to the UC520, then went in and looked at command line and CCA did not make the changes, the command line still shows all ports under the ALL_FXO TG and there is no changes in the preference for the outbound PSTN.

I reloaded CCA and it still shows the correct setup, but the command line tells a different story.

To be absolutely sure, I shutdown CCA and started it up again, and boom the commands are all back to where they were originally. (Gone)

I had the smae problem with SIP Trunk, it took the commands, applied, saved, but they were not changed on the UC520.

Me thinks there is some bugs in CCA 2.0

Skyler Spence Fri, 05/29/2009 - 14:09

Bob,

We will definitely be investigating this behavior.  If possible, could you please attach your application logs to this thread?  To do this:  Open CCA and recreate the problem (try to make these changes and hit apply), exit out of CCA and confirm that the CLI has not magically changed this time.  Next go to your install directory for CCA, the default path is C:\Program Files\Cisco Systems\CiscoSMB\Cisco Configuration Assistant.  Here you will see several text files labeled as Application_Log_Day_Time, choose the one that matches your most recent attempt time.  If you could attach this log here our top guys will be looking it over to determine what is going wrong.  We greatly appreciate your taking the time to help us troubleshoot.

Sklyer,

I could do that.....but I just finished redoing the entire dial plan in the CLI and I don't want CCA to pooch it again. Maybe this weekend when I can try writing it to the UC520 without saving and bouce the UC to bring back the original configuration.

I would now ask for an enhancement, like SDM and ASDM have a preview command before sending it to the device so at least I can cut and paste the commands (as well as see if the right ones are going into the UC520) into a text file to ensure I have them prior to the CCA "saving" them.

With my SIP trunk setup; I had a bogus entry originaly configured, then I used CCA to overwrite the configuration with a real provider. When I went back into CCA my original configuration (the bogus one) was there. I went into command line and sure enough the new parameters were not on the UC520. I hand coded them in as well to get it to work...

I understand, whenever is convenient for you to collect the log information is fine.  As to your other request, there actually exists a setting today to view the voice related commands that are sent out to the system when you click apply.  You can enable this option on the Advanced tab of the Preferences window.

From our testing, we found that the preference setting for the new FXO trunk group took effect, but there was an issue assigning the FXO port to the new trunk group. We will ensure this gets fixed in the 2.0 maintenance release.

Thanks,

Marcos

Marcos Hernandez Mon, 06/01/2009 - 06:03

Thanks for confirming. The maintenance release will correct this omission on our part.
