How to bind different IP addresses based on the PSTN physical line?

[z.zdravkov]

Hi,

I have the following case: Two E1 interfaces to the PSTN. An incoming call comes and I want to send it to the CallManager with different IP addreses (loopback) based on the E1 line. My target is to allow 7 incoming digits for the first E1 and 4 digits for the second E1.

Thank you.

Best Regards,

Zdravkov

Hi, first of all if the CM is only one, you don't need to send to different addresses, you can strip digits easily with a translation-profile at voice-port level.

But if there were two CMS and a single GW, you could use two techniques, cor and "steering digits" Both have separate incoming DP based on "incoming called-number". With COR, you distinguish which DP outgoing to use, based on COR settings. With "steering digits", the incoming DP adds a certain number to match an outgoing DP, tha number is the stripped out via translation-profile.
