hello,
i have a router 2921 with the aproprieted voice card for E1 and licenses. I would like to know how to configure it for incoming and outcoming calls. I already configured the ephone and SIP phones for internal calls. now i just need to configure it for send and receive external calls.
This is some informations about my cenario!
Router:
IOS: c2900-universalk9-mz.SPA.153-1.T
CME: 9.1
ISP from Brazil:
type: E1
signal: R2 Digital
Channels: 32
Phone Number Iniital: XXXX-9250 (main)
ephones-dn numbers: 9250 to 9280
Please if some one help me!
Best regards....

If your controller E1 is up an running, you must configure dial-peers to route calls:
dial-peer voice 10 pots
description OUT to PSTN
destination-pattern .T
direct-inward-dial
port 1/0:15 !### use your port number
dial-peer voice 11 voip
description IN from PSTN
translation-profile incoming XLATE_PUBLIC_NUM
destination-pattern XXXX92[5-8]. !### your pstn number
b2bua
modem passthrough nse codec g711alaw
session protocol sipv2
session target ipv4:10.0.0.1 !### CME ip address
session transport udp
incoming called-number XXXX92[5-8].
dtmf-relay rtp-nte
codec g711alaw
fax rate disable
fax protocol pass-through g711alaw
no vad
Probably you must use a translation rule to convert your public phone numbers to ephone numbers:
voice translation-rule 1
rule 1 /^XXXX92/ /92/
!
!
voice translation-profile XLATE_PUBLIC_NUM
translate called 1

Thanks for answer, but i resolved this problem with the configuration bellow:
Now i just have one question..... I think that the CME is taking too long time to complete de call, around 7 seconds for local calls and 12s for another city our country. Its just happen for outcoming calls.
Is It a normal time?

Your dialing delay is usual.
You can try to adjust the interdigit timer and use the # at the end of the dialed number to send the call immediately.
