Digits dropped when a phone is forwarded

Unanswered Question
May 28th, 2014
User Badges:

Hello everybody.

I have a strange issue in my CUCM 8.5 cluster (one publisher and one suscriber). I try to expain:

We have with ISP a numbering plan to have short numbers in corporative mobiles. For instance, to dial the 666666667 inside the company, it's enough to dial 29654.

When you call from any of these mobiles to any Cisco phone forwarded to any of mobile short number, one digit is dropped. Only in this scenario.

For example, you dial from 29670 to a Cisco phone forwarded to 29654 and the call goes to 9654 dial number.

 

The network topologhy is the following:

Call from mobile - ISP - Nortel CS1000 with a DSC -Cisco gateway with a dial peer - CUCM - Cisco phone forwarded - Nortel CS1000 - ISP - Mobile called.

If you call to any short mobile number from any phone which isn't forwarded, everything goes well.

 

I did several traces and the digit dropped it's shown when the call gets back to Nortel CS100 regarding the topologhy described before, so I'm thinking if CUCM uses a different route pattern when a phone is forwarded.

 

Thanks in advance.

We certainly need to look at CUCM traces to check with other route pattern is matching on the basis of CSS applied to the IP phone dn's Call Forward and Call Pickup Settings section.

Hi,

Please check the call forward CSS on the phone configuration. You may also run the Dialed Number Analyzer with that CallFoward CSS and dialed digit should be 29654.

 

If you call 29654 from the cisco phone, does it work?

 

Also check the gateway debugs to verify whether or not the complete number is received from CUCM to gateway.

 

please collect debug voice ccapi inout for a test call from the gateway and let us the calling mobile, called cisco phone number and the final mobile destination number. If not the complete running configuration, Pleas include the relevant configurations from gateway.

Hi Suresh.

 

You can see Cisco DNA log. 

If you call 29654 directly, everything goes well.

 

debug voice ccapi inout log for a failling call (calling from 27707 to 8555 forwarded to 29057):

Please Suresh, tell me the exact configuration you want to check in my gateway

It seems the complete called number is coming in to the gateway. To confirm the same, please collect the debug voice ccapi inout & debug isdn q931 for the call failure and provide us the complete log. Also please collect same set of debugs for a test call from IP phone to same mobile number.

we need to check the dial-peer configuration and translation rules if configured any. you may also post the complete running configuration if you are ok.

You can see above the voice ccapi debug for the call failure.

When you enable debug isdn q931 traces, the failure call doesn't appear.

I have a problem: I can't post here all running configuration, you know, it is a corporate voice gateway. If you tell me how, I'll show you any part of configuration.

Thanks.

Is this issue permanent or intermittent? The above posted debug will not help. You should collect the complete logs for the call failure. Please post the dialpeer configurations too.

It happens the same to all Cisco phones.

Excuse me Suresh. I don't know how to collect the traces and the dial-peer configurations. I will be very pleased with you if you help me.

Sure, you can enter the command 'show run | be dial-peers'. It will display the configurations starting from dial-peers only. you can copy and paste it here.

 

For collecting the debugs, you can follow the below steps.

Recommended Configuration:

Router(config)# service sequence-numbers
Router(config)# service timestamps debug datetime localtime msec
Router(config)# logging buffered 10000000 debug
Router(config)# no logging console
Router(config)# no logging monitor

Router(config)# default logging rate-limit

Router(config)# default logging queue-limit

Router(config)# voice iec syslog

 

<Enable debugs, then wait for issue to occur.>

...

<Enable session capture to txt file in terminal program.>

Router# terminal length 0

Router# show logging
