[cisco-voip] Interdigit Timeout on Translation

Tue Mar 18 19:37:00 EDT 2008

I guess Dial Patterns are Kind of Choose your own flavor kind of deal. Just like some people Do CTI ports instead of route points or translations instead of Dial patterns for blocking calls. The result is the same.

The thing with Route filters is that in my experience it is easier to overlook something while working with Route Filters, especially when you have several AND/NOT statements in one filter.

But as with the Auto industry Your Mileage may Vary ;-)

I hear what you are saying and I was on the fence about this one for a while, but am totally converted. I don't think I would ever create PSTN route patterns without the @ macro nor would I recommend going without it. There are definately two schools of thought here and after speaking with a number of senior Cisco techs who have been around for a while I couldn't see a reason not to proceed with not using it.

There's a certain magic involved in creating route patterns without the 9.@ and while I'm game for anything, I really have to worry about building a system that I can easily transfer ownership to and/or allow others to troubleshoot easily. Route filters are very easy to read and now that we are proceeding with toll-bypass, ahem , I mean tail end hop off, route filters are invaluable. I can imagine doing what I'm doing without them. Actually, I did - it wasn't fun. ;)

Nothing is perfect, however, and as you mention below, I am stuck with the 1024 character limit. I created a quick little spreadsheet that allows me to build and maintain my route filters rather easily and keeps count of the number of characters in each clause.

And I don't buy for a second the "all your route patterns are easily visible" - the frame layout of search results is horrible - 75% of the real estate used up for white space. grrrrr

Although you Can use 9.@, you have to be very careful with it.
Here are some recommendations from SRND for the 9.@

*The @ wildcard can be practical in several small and medium deployments, but it can become harder to manage and troubleshoot in large deployments because adopting the @ wildcard forces the administrator to use route filters to block certain patterns (see Route Filters<http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/6x/dialplan.html#wp1044192>).

Route Filters

*Use route filters only with the @ route pattern to reduce the number of route patterns created by the @ wildcard. A route filter applied to a pattern not containing the @ wildcard has no effect on the resulting dial plan.

*The logical expression you enter with the route filter can be up to 1024 characters, excluding the NOT-SELECTED fields.

*As you increase the number of logical clauses in a route filter, the refresh time of the configuration page also increases and can become unacceptably long.

*For large-scale deployments, use explicit route patterns rather than the @ wildcard and route filters. This practice also facilitates management and troubleshooting because all patterns configured in Unified CM are easily visible from the Route Pattern configuration page.

We have international route patterns (using route filters) and we can dial the octothorpe (mmmmmmmm, octothorpe) to bypass interdigit timeout and we do not have the octothorpe in the route pattern. We have 9.@ - I think this is another advantage to using @ patterns it recognizes end of dialing pattern as a possibility.

So I added the octothorpe to the end of the international pattern and then to the end of the translation pattern and that works.  Only downside is that now you are required to hit the "#" at the end of dialing all international calls.  That's probably a good thing, but is a change from what people are already use to.

Thanks,

Carlos

Re: [cisco-voip] Interdigit Timeout on Translation

How are you using the octothorpe? Was it inserted at the end of the international pattern?  If at the end of the pattern, CCM should know to stop waiting to perform digit analysis once its received since you'll be matching an explicit pattern.

Also, how are you using your translation patterns? I would make sure the called party transformation isn't stripping the #. You want the translated called party number to match your  # international pattern (eg  9.011!#). Speed dial = 3377# à TxPattern = 33XX#, Prefix= 9011<number> à RP = 9.011!#

I am setting up some speed dials using translation patterns for International locations.  Is there any way to avoid waiting for the inter digit timeout at the end of the pattern?  I thought you could bypass it with the "#" but that does not work.
