Fax Onramp with T1-CAS

procopius1980 · ‎11-14-2012

I am encountering difficulty with configuring Fax Onramp with a T1-CAS connection. The problem is that my POTS dial peer, once applied to a port, immediately catches and black holes every inbound call. Here is sample from a debug:

*Nov 14 19:02:58.345: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:

Calling Number=, Called Number=, Voice-Interface=0x453F42F8,

Timeout=TRUE, Peer Encap Type=ENCAP_VOICE, Peer Search Type=PEER_TYPE_VOICE,

Peer Info Type=DIALPEER_INFO_SPEECH

*Nov 14 19:02:58.345: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:

Result=Success(0) after DP_MATCH_PORT; Incoming Dial-peer=5551234

I have a dial-peer configured to match traffic coming into 555-1234 and send it to an MMOIP dial peer. Our router strips all digits but the last three.

dial-peer voice 5551234 pots

service onramp

destination-pattern 234

information-type fax

forward-digits 0

Port 0/0/0:0

dial-peer voice 3000 mmoip

service fax_on_vfc_onramp_app out-bound

destination-pattern 234$

information-type fax

session target mailto:admin@mycompany.org

http://www.cisco.com/en/US/docs/ios/12_1/12_1xi/feature/guide/dt_xifax.html

Here is the guide that tells you to set information-type fax on the POTS dial-peer.

I appreciate any help I can receive. I will be more than happy to provide more detail if requested.

You need to use incoming called-number, not destination-pattern.

procopius1980 · ‎11-14-2012

I have tried both. I appologize for not making that clear. I just changed the dial-peer to use incoming called-number instead of destination-pattern. All calls immediately black holed as soon as I applied the dial-peer to the port.

Thanks,

paolo bevilacqua · ‎11-14-2012

That should not be the case, remove port and destination-pattern, even if the doc says otherwise.

procopius1980 · ‎11-14-2012

I have removed the port and destination-pattern. Here is what my dial-peer looks like:

dial-peer voice 5551234 pots

service onramp

information-type fax

incoming-called number 234

foward-digits 0

Debuging using debug voip dialpeer all shows that the call gets matched to the VOIP dial-peer (dial-peer 100) that routes the call to Call Manager. Dial-peer 150 is a backup.

description Incoming Calls

destination-pattern [2,3,4,5,]..

session target ipv4:10.1.1.1

dtmf-relay h245-alphanumeric

Like you said from the beginning, using incoming called-number should have matched the incoming call. Thank you for working with me!

Here is some additional information that may or may not be pertinent.

Our T1 controller is broken into two groups:

controller T1 0/0/0

framing esf

linecode b8zs

cablelength long 0db

ds0-group 0 timeslots 1-12 type e&m-wink-start

ds0-group 1 timeslots 13-24 type fxo-ground-start

Channels 1-12 are for inbound calls. Channels 13-24 are for outbound. Setting the POTS dial-peer to port 0/0/0:1 (the outbound channels) causes the POTS dial-peer to be matched, but of course nothing happens. You just get a dial-tone from your test fax.

paolo bevilacqua · ‎11-14-2012

In many case debug doesn;t show incoming DP at all, so that's normal

Do you have the onramp tcl files, fax-interface mail and the needed reboot after that ?

procopius1980 · ‎11-26-2012

My apologies for the delay. I have been on holiday.

Yes, I have the app_faxmail_onramp.2.0.1.3.tcl file in the flash and I have entered fax interface-type fax mail + reboot. I noticed you wrote files, did I need anything else?

Additionaly, I have already had a voice specialist look over my config. He has performed many fax onramp jobs and confirmed that I had everything setup correctly. He thinks the issue is due to the fact that I am using a T1-CAS for voice service. His advice is that I contact Cisco TAC.

Thanks,

paolo bevilacqua · ‎11-26-2012

I don't think so, you can also the "debug voice application tclcommands" to check if the service script is invoked.

procopius1980 · ‎11-26-2012

The debug did confirm that the script is getting invoked. I still have the problem where every call gets matched and dropped by the POTS dial-peer. I basically kill all inbound calls once I apply the port to the dial-peer. Here is the debug output that writes to the screen as soon as I apply the dial-peer to the inbound port:

bctyvg(config-dial-peer)#port 0/0/0:0
bctyvg(config-dial-peer)#
*Nov 26 19:58:33.510: //-1/xxxxxxxxxxxx/DPM/dpCheckTerminationStatus:
bctyvg(config-dial-peer)#

Thank you for your continued assistance.

paolo bevilacqua · ‎11-26-2012

For incoming DP, 'port' is not needed, matching is done on called number.

You may have other things in config preventing this to work.

procopius1980 · ‎11-29-2012

Here is my router's running config. I did not set anything up on this router except for the Fax Onramp information. I am very inexperienced in voice. Thank you for the help.
