MFCR2 on 5300 E1-PRI

Hi All !

I have connected 5300 E1-PRI with PSTN Exchange using ISDN Signaling and its working fine. The problem we face is the secondary dial-tone which cannot be removed due to certain exchange limitation. Now the Exchange Engineer is asking me if i could configure MFCR2 on this line ?? Is it possible if so then what will be configuration. I have done a search on cisco but couldn't get any productive material. Help Please !

Re: MFCR2 on 5300 E1-PRI

Hi,

I don't understand what you mean by 2nd dial-tone. Is this an inbound

call into the router and you hear another dialtone play by the router?

If so, you can enable "direct-inward-dial" (aka DID) on the router and router will not play the 2nd dialtone and just use the DNIS received in the ISDN SETUP message to route the call.

You can do the following:

dial-peer voice 1 pot

incoming called-number .

direct-inward-dial

port x:d

For more information on

As for the E1R2 signaling, YES, the router is able to support E1R2.

Here is more information regarding E1R2:

Re: MFCR2 on 5300 E1-PRI

Hi Chinh,

Thanks for your reply. I have the DID config on my 5300. Its working on all other sites, still other sites were also creating issues of timer expiry and digit collection but a fine tunning of timers rectified it . Only this site is not working may be due to compatibility issue with the SEIMENS exchange ( a very old one). Users have to dial digit 7 before dialing there number. . My configuration is:

!

interface Serial0:15

no ip address

isdn switch-type primary-net5

isdn overlap-receiving

isdn incoming-voice modem 64

isdn map address .* plan isdn type subscriber

isdn bchan-number-order ascending

fair-queue 64 256 0

no cdp enable

!

dial-peer voice 201 pots

destination-pattern 012T

port 0:D

prefix 2

!

dial-peer voice 12 pots

incoming called-number .T

no digit-strip

direct-inward-dial

!

I never new that MFCR2 is E1R2 signaling thanks for info, i have configured it using channel Bank to terminate analog lines. Still i will study these links for further command on it. Any other openion will be helpful. Thanks
