Campus Faxing

I have a 2600 with a PRI terminated and on a second 2600 on the campus I want to send a fax to the FXS port. What is the proper methodoloy for this? I wanted to translate and send to a dial peer but don't see how to a second router.

Thanks for any guidance.

Re: Campus Faxing

So you have PRI--GW1---(??? protocol ???)--GW2--FXS--FAX

You could use H323 as your protocol, and do something simple like:

GW1:

dial-peer voice 1 pots

port 0/0:23

direct-inward-dial

incoming called-number .

destination-pattern .T

dial-peer voice 2 voip

description fax to number 5551234

destination-pattern 5551234

session target ipv4:2.2.2.2

codec g711ulaw

modem passthrough nse codec g711ulaw

no vad

GW2:

dial-peer voice 1 voip

incoming called-number .

destination-pattern .T

session target ipv4:1.1.1.1

modem passthrough nse codec g711ulaw

codec g711ulaw

no vad

dial-peer voice 2 pots

port 0/0/0

desination-pattern 5551234

description FXS to fax machine

Re: Campus Faxing

Thank you for your help.

That makes a lot of sense and I put it in.

The call now gets to the second router, but does not terminate on the FXS card.

The debug voice dialpeer inout shows the call coming in at the . but matching that dp not the one pointing at the FXS port.

Any idea?

Re: Campus Faxing

You should change the destination pattern on your FXS port pots dial peer, or change the way you're dialing from the other site. It's hard to tell you without details.

Re: Campus Faxing

Is this enough?

I'm ready to try destination-pattern 548. since exact match doesn't.

Re: Campus Faxing

You would need to post the part that has the --cisco-dest:

(it's a big block of debugs in debug voip ccapi inout)

It's very possible that you're not getting exactly 4 digits - try configuring the destination-pattern as the 10 digit number or however the other gateway is receiving it from the PSTN.

Re: Campus Faxing

First I have to thank you for the help.

I'm going nuts and don't see what is wrong.

I think I have all of the information in here. xxxxxxx is me taking actual numbers out. 7053 is my cell phone, 5486 is the destination fax. To me it looks like it never matches to the destination.

Re: Campus Faxing

Looks like it should match the outgoing dial peer.

What does 'show dial-peer voice summary' show for the outgoing dial peer?

Re: Campus Faxing

The show dp v sum is UP UP.

I've rearranged the dial-peer order, I've changed the dp in different trys.

The call comes in on the voip dial-peer and will not go to the FXS.

I can call fxs port to fxs port, so the destination dp works. The voip dp is not searching the dp list from the top after the call comes in.

This is a new fxs card that I installed.

The station to station tells me it is ok.

What next?

Thank you again for your help.

Re: Campus Faxing

The ccapi debugs you sent weren't complete. Either something is causing that problem also, or it just wasn't the full debugs.

It sounds like there is some other configuration playing a part here.

Re: Campus Faxing

This was a site router with CME and CUE configured at one time. With consolidation, it is currently a router on a stick used for overhead paging through an FXO (works) and the FXS that was just added for a fax machine. I've removed the sccp and shutdown all the unused interfaces and the service-engine/0. There is some more I could remove, but all shutdown. What bothers me is the debug voice dialpeer inout showing that the call comes in on the right voip dp but never goes to the dp pots with the destination coded on it. I've rearranged the order of the dial peers so that the exact match pots is prior to the dial peer voip. I thought once the call came in on a dial peer, a linear search of dial peers from the top occured to determine if the call was destined for somewhere else. That search is not happening or is happening incorrectly.

Thank you again for you help.

Phil

Re: Campus Faxing

Hi Phil,

Try this:

dial-peer voice 3

shut

Since the destination-pattern is 54.. it is overlapping with the other dial peer.

If you were to add:

voice service voip

allow h323 to h323

You would probably see this call routing out that way.

hth,

nick
