Help needed on E1 PRI with DID

I have a as5350 router configured with DID for the E1 line witch connects me to the telco.

first of all I see isdn "incoming-voice voice" every where in cisco but there is only modem/data on the CLI of the router, which one is correct. secondly,

outbound connections work but with a number that is not defined in the the local network.(DID is not working as it should be), inbound connections from the PSTN does not work at all. heres the config

!

controller E1 3/0

pri-group timeslots 1-31

!

interface Serial3/0:15

no ip address

isdn switch-type primary-net5

isdn incoming-voice modem

no cdp enable

!

!

voice-port 3/0:D

!

!

dial-peer voice 10 pots

incoming called-number 1234....

direct-inward-dial

Re: Help needed on E1 PRI with DID

First in order to process calls on this E1-PRI make sure you change the "isdn incoming-voice modem" command to "isdn incoming-voice voice" under the serial interface.

Also, change the

dial-peer voice 200 pots

port 3/0:D

to

dial-peer voice 200 pots

port 3/0:15

Change this dial-peer:

dial-peer voice 10 pots

incoming called-number 1234....

direct-inward-dial

to

dial-peer voice 10 pots

incoming called-number 1234....

direct-inward-dial

port 3/0:15

How many digits is telco sending to you? (you can use debug isdn q931 to figure it out)

Your incoming dial-peer will only match DID calls that are 7 digits and begin with 1234.

HTH, please rate all posts!

Re: Help needed on E1 PRI with DID

Thank you for your repy,

actually one of the things I was puzzled with was the command "isdn incoming-voice voice" command witch does not exist. the only commands available are data and modem. (the as5350 has an IOS of c5350-is-mz.123-11.T11 with a 4 port e1 pri module and two np-60 modules.). Same goes to the dial-peer command it only accepts "d or D" as it states in the CLI.

The telco is sending me 8 digits.

What do you think?

thanks in advance

Re: Help needed on E1 PRI with DID

I have checked this again with no luck.

Can any one help me on this?

Re: Help needed on E1 PRI with DID

Your configuration look OK. On AS5350 there is no isdn incoming-voice voice command. Instead you should use incoming-voice modem, which you already have done. And add compand-type and cptone to voice-port.So potential problem could be with number translation. What you should try is to connect a SIP phone and make dial-peer voice to that phone and with appropriate translation test DID.
