understanding the translation-rule

[binaryhealer]

hi

i need some help uderstanding the translation profile. you we have a siemens ipbx on one side and a cisco 28xx on the other.

i wanted to create a dial code of 4+xxx (xxx for the extension number of the remote site, since we have overlapping numbers) but i would like the cisco equipment to strip off the 4 and leave just the 3 extension number.

for incoming calls as well, i would like the cisco to strip off the 4 and leave just the 3 numbers before routing to the ext. this is all voip calls

would this be correct:

translation profile to be used in dial plan

/4.../ /.../ for outgoing calls

/4.../ /.../ for incoming calls.

thanks in advance.

These are my similar rules, they strip the prefix 2255 and maintain the rest of the number:

voice translation-rule 10

rule 1 /^2255/ //

!

voice translation-rule 11

rule 1 /^2244/ //

!

!

voice translation-profile STRIP_PREFIX_2244

translate called 11

!        

voice translation-profile STRIP_PREFIX_2255

translate called 10

hi

thanks for the reply:

so basically we need to just create a rule:

rule x/^4/ //

and that will strip off the 4 and leave the other number?

please let me know.

thanks

[Daniele Giordano]

Yes. For me It works.

More specific one:

Voice translation-rule 1
rule 1 /^4\(...$\)/ /\1/

For outgoing:
Voice translation-profile OUT
translate called 1

Apply this under dial-peer

Similar for incoming.

thanks for the reply. it works for outgoing calls.

this is my config for incoming

translation-rule 20

rule 1 /^4\(...$\)/ /\1/

translation-profile incoming-ho

translate calling 20

i apply this to the dial-peer, but its not working. the incoming ipbx is a siemens. i talked to the siemens guys they say that siemens sends all the digits.

dial-peer voice 4000 voip

translation-profile incoming incoming-ho

translation-profile outgoing gdp-in

destination-pattern 4...

session protocol sipv2

session target ipv4:192.168.128.100

codec g711alaw

do i need to specify any other config for it to translate the incoming call.

thanks in advance.

[Daniele Giordano]

Probably incoming calls don't match the dial-peer 4000.

Use "debug voip dialpeer" to check the exact match of incoming calls.

hi thanks for the reply. i am abit new to cisco. can you help out with the debugging. i read the docs seems like a lot of options.

after i enable how do i view the logs? show logs?

thnks in advance

[binaryhealer]

hi

i managed to enabling debugginand viewed logs. but i saw no calls coming from the siemens ipbx. do you think i enableing all debuging?

[Daniele Giordano]

If you are connected to the router via telent, try this:

router# term mon

router# debug voip dialpeer

The logs are shown on your screen in real time.

After a call you can disable the debug using

router# undebug all

Check if the debug is off using

router# show debug

Post the output.

Regards.

[Daniele Giordano]

Alternatively you can use this show command during an active call:

router#sh voice call status

CallID     CID  ccVdb      Port        Slot/DSP:Ch  Called #   Codec    Dial-peers

0x7937D    92   0x64A7782C 1/0:15.1         0/1:2  123456789 g711alaw 200/1000

0x7937E    96   0x64DF86B4 1/1:15.1         0/1:1  123456789 9600     1000/202

2 active calls found

For each call there are always an incoming and outgoing dial-peer.

Regards.

hi Daniele

thanks for the reply. there nothing being displayed on the mon.

this is our setup

siemens <---------- cisco cme (dialing ok)

siemens -------->cisco cme, dialing not ok.

how can i check on the cisco whether the call is reaching the cme. i can ping no problem. all protocols are open. is there a way to check why the calls are being rejected.

thanks in advance.

[binaryhealer]

just 1 other point, the call doent go through from the siemens.
