filiberto.aguirre · ‎06-25-2010

Hi,

I want yo make call to PSTN taking digital trunk of my central site when I dial from my remote site. I want to dial 3+7 digits then add the prefix 901984 to the 7 digits, after this send this digits to my central site. E1 in central site is working fine, and there is a VPN site to site already working.

REMOTE SITE

voice translation-rule 1
rule 1 /^3\(.......\)/ /901984\1/
!
!
voice translation-profile PLAYA_POR_OJO
translate called 1

dial-peer voice 1500 voip
description a salida por OJO desde Playa
translation-profile outgoing PLAYA_POR_OJO
destination-pattern 901984.......
session target ipv4:172.16.0.1 -----> CME of central site
dtmf-relay h245-alphanumeric
ip qos dscp cs5 media

CENTRAL SITE

dial-peer voice 901 pots
corlist outgoing LADA
description LD National
destination-pattern 901..........
direct-inward-dial
port 0/0/0:0
prefix 01

with this config I can not take trunk in central site , when I dial from remote site,,,,, I do not know why??

Your dial-peer config should look like this

dial-peer voice 1500 voip
description a salida por OJO desde Playa
translation-profile outgoing PLAYA_POR_OJO
destination-pattern 3....... !<---------
session target ipv4:172.16.0.1 -----> CME of central site
dtmf-relay h245-alphanumeric
ip qos dscp cs5 media

Since you are dialing 3+7 digit, it should match dial-peer first and then get translated on the way out.

Hope this helps.

thanks

Hi,

Try changing the translation-profile from outgoing to incoming on dial-peer voice 1500 voip.

PLZ Rate if you find this helpfull.

Hi abu,

Finally I found the error, in addition to change the destination pattern as you told me , I had to change the prefix in central for the dial peer.

Thanks a lot for your time
