[cisco-voip] forward-digits or caller-id

Wed Dec 6 14:14:22 EST 2006

Something is telling me this is not my problem here. I added this dial
pattern and the phone provider (not the CO but another party in the mix) say
they are seeing a number 10400 being passed. This number is nowhere in the
CME config whatsoever. An interesting thing that I saw while show call
status is that on an inbound call it says the following:

CallID     CID  ccVdb      Port        DSP/Ch  Called #   Codec
Dial-peers
0x19F5     149B 0x4642A6EC 0/0/0:23.1  0/1:1   10400      g711ulaw 3/20063
0x19F6     149B 0x4692E924 50/0/37.0          *10400      g711ulaw 20063/3

That is an inbound call coming from their third party device here. I find it
interesting that this inbound callerid is the same thing they are seeing on
outbound caller id. It seems to me that this problem is in their box. Here
is the setup

PRI -> Thrid Company router -> CME. It is PRI from their router to the CME
as well. 

Can anyone shed some light on this issue.

And I want to thank everyone sofar for the TONS of help you have been!

You just need the numbers in the command, not the dash.

Dialplan-pattern 1 703555.... extension-length 4 extension-pattern ....

As for the carrier, it depends on what they are looking for in the number,
if it is good to them or not, etc. 4 digit extensions on the PSTN aren't
really valid. I have seen carriers take anything for a calling party number
and others who reject them (ie: 4 digits, numbers with # in them, etc). I
have also seen where customer calls work fine for a long time with 4 digit
calling party number, etc (typical CCM behavior with default settings where
4 digit extensions are used if nothing was done with caller id/calling party
settings) then something changed in telco/carrier land and calls have
problems due to caller id issues that need correcting.

As a general rule of thumb, I find it good practice to use a valid 10 digit
number for calling party # that is assigned to the customer. But this may
depend on carrier, etc.

In the end, this boils down to what your carrier is looking for as
there are no real rules and it depends on what they want to see or not
see. This also extends to other carriers the call routes through to get to
the destination, as your carrier may be fine with the caller id settings but
the carrier the number terminates at may not like it.

Thanks. So if I have this right it should be like this:

Numbers are 703-555-XXXX where the X are the extension numbers

Telephony-service

Dialplan-pattern 1 703-555.... extension-length 4 extension-pattern ....

So when extension 1234 dials out it will pass 703-555-1234 to the provider?

Sorry for my inexperience with this but they did not have this trouble with
their old provider, I guess they took care of setting this. Can anyone give
me a reason their current provider couldn't do this as well other than
laziness?

Thanks

There are a couple ways this can be done.

Under the telephony-service, you can use the dialplan-pattern command to do
this. An example would be 'dialplan-pattern 1 414555.... extension-length
4'. 

You can also use translation profile/rule on the dial-peers to modify the
calling party number, or
under the ISDN D Channel, you can hard set the caller id also for all calls.

The forward-digits command, applies to the number called and how many digits
of that to send so doesn't effect the calling party number. For example if
you had forward-digits all on a dial-peer with destination-pattern of 9T and
you called 918005532447 it would send 918005532447 to PSTN or whereever
dial-peer was sending call to. A forward-digits of 10 would send 8005532447,
forward-digits of 4 would send 2447 and so forth.

HTH,  Erick

I am a bit confused. A new phone company for a client of mine is telling
them they need to pass 10 digits to them, where as now they are apparently
only passing 4, thus callerid to outside users is showing up as only the
last 4 digits. My question is, is this accomplished by setting the caller-id
= local on the ephone-dn or is this accomplished by forward-digits 10 (or
all) on the dial peer for the 23 channels of the PRI?

Thanks

Curt
