The 00 can be added from the cucm as well as from gateway.
we need to find out from where the 00 are added.
kindly run Dailed number Analysis (DNA) and share the out put.
Also share the gateway configuration.
From gateway debug isdn q931 if it’s pri
And if it’s sip provide the output of debug voice ccapi inout
Share the voice gateway configuration.
Also share the output of debug voip ccapi inout if its sip
And if PRI share the debug isdn q931
For DNA
Go to CUCM Serviceability page
It shows the result on a popup window. Share the screenshot and it contains the call flow.
Hi Kaleem,
Could you please send another screenshot with an expanded transformation mask?
might have enabled logging buffer (logging buffered 10000000). Please enter show log and see if it displays anything. Its better you clear all the logs (clear logging) and make another test call, and input show log.
Share both the expanded screenshot and debug output.
Regards
I have checked your config and this is what I would suggest that your do.
voice service voip no allow-connections h323 to h323 no allow-connections h323 to sip no allow-connections sip to h323 no allow-connections sip to sip ! sccp local GigabitEthernet0/0/0 sccp ccm <IP of CM CPE 1> identifier 1 version 7.0 ;our standard is that identifier equals last digit in CM IP address sccp ccm <IP of CM CPE 2> identifier 2 version 7.0 sccp ccm <IP of CM CPE 3> identifier 3 version 7.0 sccp ! sccp ccm group 10 bind interface GigabitEthernet0/0/0 associate ccm 1 priority 1 associate ccm 2 priority 2 associate ccm 3 priority 3 associate profile 1 register <name>_xcode !

For conference bridge profile always use an even number as it will always use the entire slot in the DSP anyway. so setting it to an uneven number wastes DSP resources. no shutdown ! dspfarm profile 1 transcode no maximum sessions no codec g729br8 no codec g729abr8 maximum sessions ? ! need to check what is available, then to max what your have. no shutdown ! dial-peer voice 351 voip no incoming called-number . ! dial-peer voice 357 pots no translate-outgoing called 1 no direct-inward-dial default forward-digit ! dial-peer voice 359 voip no incoming called-number . ! dial-peer voice 1351 voip no incoming called-number . ! no ip default-gateway 172.16.35.254
Most of these change has noting to do with your issue as such that you ask about, but are either wrong configuration or at least not needed. The parts in bold text is related to your question.
This is what is making the 00 be sent to the service provided for international calls. In general you should avoid using the old type of translations and use voice translation rules instead as they are more powerful.
translation-rule 1
Rule 0 ^900 00
By my account this in effect drops the 9 and keeps the double 00, if the intent was to drop all the rule should have been ^900 <nothing>, but as stated you should really use voice translation rules instead or just let the default number cosumption on POTS dial-peers do its work on this. The later is what I have suggested in the configuration changes.
Also doing this is a very bad practice.
voice service voip
ip address trusted list
ipv4 0.0.0.0 0.0.0.0 ! Doing this is very bad as you would turn off all built in security for the call service. Better to add the IPs that you know that the gateway would interact with directly, like your CM nodes IPs for example.
About not seeing any output from the debugs I assume that you did "term mon" to get the output into the terminal where you'd connected? To turn off the output do "term no mon". If you still do not see any output check that you do not have "no logging monitor" in your configuration as that would stop anything to be written to the terminal.
translation-rule 1
Rule 0 ^900 00
The above rule gets applied when he dial 90060054602. But asper the DNA, he dials 960054602.
Your absolutely correct @Nithin Eluvathingal I stand corrected.
@kaleemullahbilal1 then you'll need to continue to search for where the number is transformed.
Kindly share the expanded DNA screenshot. Need to see if there exist any translations getting applied before sending the calls to gateway.
Turn ON Terminal Monitor when debugging. Then issue debug voip ccapi inout or debug isdn q931 commands.
As @Roger Kallberg mentioned, fine tune your configurations asper the best practice.
Type 7 password is getting deprecated move to type 9.
Please state clearly what is the number you call to, list it as is when it leaves the CM to the GW and what you'd want it to be when it leaves the GW to your service provider, aka to PSTN.
As you list it now you say that "00" should not be sent to the SP and then you show the number as "600546002", quite confusing. ':-|'
Do you want to just remove 00 from the early part of the number, ie keep 66546002? Or do you want to get rid off all instances of 00, ie send 65462? I assume that it something all together different, but as you open up for interpretations by not providing very clear information to start with it's not easy for us to know.
