Really strange problem

Hi i have a ccm 4.1(3)sr3a where i configurated a route pattern like this 9.9! so the callmanager is discarding pre dot and then send all the other numbers to the gateway. The problem is that when we call from an ip phone a number like 9.929323456 we receive a response from the carrier that says that the number is wrong but when i call that same number from my cellphone it works. The route pattern works with all other series 9[3-8]xxxxxx but with the series 9[1-2]xxxxxx i receive a prompt from the cellphone carrier that says that the phone is wrong.

Please give me a hand with this, thanks in advanced.

Re: Really strange problem

You doing 911? Probably not sounds like it isn't in the US.

Re: Really strange problem

Do you have an ISDN GW ?

If so please check output of debug ISDN Q931.

If not ISDN, there are other debugs that let you see which number is being dialed, but it is little more complicated.

Re: Really strange problem

Hi, i obtained this thread:

Bearer Capability i = 0x8090A3

Standard = CCITT

Transfer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xA9839A

Exclusive, Channel 26

Calling Party Number i = 0x0081, '625'

Plan:Unknown, Type:Unknown

Called Party Number i = 0x80, '92789959'

Plan:Unknown, Type:Unknown

Feb 5 15:23:56.567: ISDN Se0/0/0:15 Q931: RX <- CALL_PROC pd = 8 callref = 0x8010

Channel ID i = 0xA9839A

Exclusive, Channel 26

Feb 5 15:23:56.599: ISDN Se0/0/0:15 Q931: RX <- DISCONNECT pd = 8 callref = 0x8010

Cause i = 0x8281 - Unallocated/unassigned number

Do you see something out of normal, i think it is a problem from the carrier.

Re: Really strange problem

You are receiving the disconnect message from your Carrier. You are sending 8 digits as your called party number with an Unknown Type, I recommend you to get in touch with your carrier and ask them why are they dropping the call and also check if they need to receive something else.

Re: Really strange problem

Hi Pepito, to add to what jbarcena rightly said, check that telco perhaps wants you to send the correct calling number, and ISDN type, and national plan. both things can be done at interface level configuring

isdn calling-number XXX

isdn map ........ plan isd type national

also please add isdn sending-complete that is always a good thing.

the above assumes you are dialing 8 digits, it the dialplan for Peru made with 8 digits ?

Re: Really strange problem

Hi, thanks for all your replies. The peruvian dialplan for cellphones have 8 digits but we use numbers from 7 and 9 digits too.

I am expecting for a response from the carrier, thanks for the help again.

I let you know.
