Dial Peer Issue

[fasteddye]

We have a Cisco 2811 that is in between our RightFax Server and our Cisco 3845 Cube Router.  We have SIP trunks but our provider is not T.38 compliant so that is why the 2811 was put in place.  This has been in place for over a year without any troubles.  We have now come across a particular local number that we are unable to fax to.  We can call this fax number for our IP Phones and get a fax tone.  We ran WireShark from RightFax server to find that the SIP invite gets a 404 code which may mean it does not know how to route the call. 

I also see the follwing from the 2811 log,

//204128/B3FB5F1E857D/CCAPI/ccCallDisconnect:

   Cause Value=1, Call Entry(Responsed=TRUE, Cause Value=1)

   Disposition=0, Interface=0x47A6245C, Tag=0x0, Call Id=204128,

   Call Entry(Disconnect Cause=1, Voice Class Cause Code=0, Retry Count=0)

   Disposition=0, Interface=0x47A6245C, Tag=0x0, Call Id=204128,

   Call Entry(Disconnect Cause=1, Voice Class Cause Code=0, Retry Count=0)

I could attach the number being dialed and the dial peers off that router if helpful.

Thanks.

[dijohn]

Yeah   please attach the dial-peers

and a full debug of the call.

Debug ccsip message

debug voip ccapi inout

[fasteddye]

Thanks for the reply.

I was not able to see any debug output with either Debug ccsip message or Debug voip ccapi inout.  Not sure if I did not see any output with those debug commands on since this router is in between RightFax and the Cube Router.  Doing a show debug lists that they are actively debugging and I issued the terminal monitor command as well.

Below are the dial peers on this router.  Sorry I only knew to paste them into this reply.  I tried to label the few dial peers that point to an ip.

Hope this information is helpful.

Thanks again for any insight you may be able to give.

The fax number dialed that we are having the issue with is 982-0xxx.  I am not sure which dial peer this number would attempt to use.

Hi,

For the Fax number 982-0xxx, the below dial-peer would be matched.

dial-peer voice 2 pots

destination-pattern [2-9]......

progress_ind setup enable 3

progress_ind progress enable 8

incoming called-number .

direct-inward-dial

port 1/0:23

You need to make sure that the call routing is properly been implemented..

I guess I am a little confused since the dial-peer on this router (dial-peer voice 2 pots) appears to be sending the call over to the Cube Router on port 1/0:23.  Our IP Phones go through the Cube Router and they are able to dial the fax number and get fax tone.  That would tell me the Cube Router knows how to route the call.  I have just done some testing to find out that any 986-xxx or 987-xxxx fax number is having the same issue.  It appears that any local fax number that starts with 9xx-xxxx is having trouble.  With that said, IP Phones dial a "9" to get outside line.  Would this point more to 2811 or Cube Router issue?

[dijohn]

You can try show dialplan number to get which dial-peer would the outgoing call match.

Else run

debug voip ccapi inout

Search for "outgoing" in the debug.

[dijohn · Accepted solution]

Can you make a test call from the IP Phone then the rigthfax server to the same number.

Collect the debugs.

debug voip ccapi inout

debug ccsip messages

on both the 2811 and the CUBE router.

It looks like a dialplan issue. Check your dial-peers else give me these debugs and the relevant dial-peers. (probably the entire set of dial-peers on both routers.)

FYI Disconnect Cause=1 points to unallocated number

[fasteddye]

It was definitely a dial-peer issue but more specifically the translation-rule on the dial peer. 

With some TAC assistance a new translation-rule was created and used with the dial-peer.

The dial-peer being used when 9xx-xxxx was being faxed was stripping the leading "9" so only sending 6 digits to the CUBE.  This dial-peer is also used for another purpose for certain calls coming out of CUCM.  CUCM calls require a "9" for outside line access.

It was using this translation-rule

voice translation-rule XXX

rule 1 /91/ /1/

rule 2 /9/ //

This was the translation-rule added

voice translation-rule XXX

rule 1 /^9\(......\)$/ /9\1/

rule 2 /91/ /1/

rule 3 /9\(..........\)$/ /\1/

rule 4 /^9\(.......\)$/ /\1/
