Interdigit timeout issue for 7 digit calls
|
|
| Erick Bergquist 2005-09-16, 2:45 am |
| Hi,
Have an issue where it takes 10-12 seconds for a call
to get placed out a gateway. It is a ISDN PRI and the
debug isdn q931 doesn't show activity until 10-12
seconds after the call is placed on IP Phone and when
we lower the T302 timer it gets placed to what T302 is
set to.
There are no conflicting or overlapping route patterns
that we can find, and we put in a route pattern for
the full number with no wildcards and same thing.
I've done a CCM detailed trace and am seeing large
delay between when the phone dials the number and when
it gets processed. Theres like a good 12 seconds in
trace where the call reference is not listed.
This is on CCM 4.02a SR2a.

| Hi Erick,
In the CCM trace look for the Digit Analysis Results, for example:
09/15/2005 16:37:19.435 CCM|Digit analysis: analysis
results|<CLID::StandAloneCluster><NID::10.10.10.3><CT::
1,100,119,1.499977><IP::10.10.21.7><DEV::SEP00115CBAD09E>
09/15/2005 16:37:19.435 CCM||PretransformCallingPartyNumber=9193
|CallingPartyNumber=9193
|DialingPartition=par-internal
|DialingPattern=9190
|DialingRoutePatternRegularExpression=(9
190)
|DialingWhere=
|PatternType=Enterprise
|PotentialMatches=NoPotentialMatchesExis
t
If it has PotentialMatches=NoPotentialMatchesExist
then CCM does not
have any other patterns it can match. If it has something else, such
as PotentialMatches=PotentialMatchesExist or
PotentialMatches=ExclusivelyOffnetPotent
ialMatchesExist, then this
means CCM has matched a pattern but can match other patterns if more
digits are dialed.
The easiest way I have found to find overlapping patterns is to go to
Route Plan > Route Plan Report. Click on the "View in File" link on
the right side. Then view the CSV file in Excel. This provides a view
of the configured route plan in SQL. If this doesn't help then you
will need to look at the dialing forest on the node that the phone is
registered to. Follow these steps to dump the dialing forest:
- Enable the "Dialing Forest Dump Enabled" CallManager Service parameter
- Dial **##*4 on the IP Phone that is placing the test call - you will
hear reorder
- Search for "dialing forest" in the latest CCM trace on the node the
phone is registered to
Dumping the dialing forest can be CPU intensive in a large network. I
have not had issues with this in smaller networks but do be careful.

| This is almost certainly interdigit timeout. Which, like you mentioned is usually caused by route patterns of varying length which have similar digits. However, in the case of 7 digit local dialing, you have to add a route filter that has 'local area code does not exist' as one of the clauses to your route pattern if you are using 9.@ in order for calls to be processed immediately after the first 7 digits.
Let us know if this helps.

Kevin,
Thanks. Yea, it does say ExclusivelyOffnet matches
exist.
Here is the info from the route list, view in file for
route patterns for call that are overlapping
(overlooked this before for some reason, didn't catch
it).
9.[2-9]XX[2-9]XXXXXX,,PT-10-DIGIT-DIALING,Route,DAYTON-RL,DAYTON-RL
9.[2-9]XX976XXXX,,PT-BLOCKED-TELESCAMS,Route,DAYTON-RL,DAYTON-RL
9.[2-9]XXXXXX,,PT-7-DIGIT-DIALING,Route,DAYTON-RL,DAYTON-RL
Is there a better way to make the 7 digit dialing rule
other then using rules for each local prefix? IE:
9.296XXXX, etc?
BTW, We also put in a route pattern of 9.2791234 and
still had issue and traces used that pattern. Or would
that overlap with the 10 digit pattern still?
Thanks

| We went with a 9.@ with local area code does not exist filter and then added another with a filter that of local area code = 519. (our local area code) We basically let the PSTN notify the user if they dialed a number not in our exchange etc.
Our dial plan consists entirely of 9.@ with filters rather than the manual entry of the 9.[2-9]XXXXXX sorta thing.
I spoke to a number of TAC engineers at Networkers and CIPTUG and couldn't get a straight answer as to which is better or worse or if there are any caveats to choosing one over the other.
I wouldn't mind hearing comments from the group about the two options.
