[cisco-voip] Need help with SIP FAX Configuration.

[Hamu Ebiso]

sorry  I was out on vocation!!


Yes the voice gateway is connected to service provider via ISDN.

yes I am expecting calls to come in from the service provider, match a 10 digit number and go to the FAX dial-peer? (ie not going to CUCM at all.

I'm using T.38
yes the fax is expecting TCP.
onsite contact is not available this week and will attach when the person comes back from vacation.

thanks

Can you explain the setup a bit further?



Is the Voice Gateway connecting to a service provider? SIP /ISDN?

Are you expecting calls to come in from the service provider, match a 10 digit number and go to the FAX dial-peer? (ie not going to CUCM at all?)

Are you using T.38/ G711?

TCP / UDP?  (Is the FAX expecting TCP which I think is the default dial-peer configuration).

Can you share the debug ccsip messages?





Cheers

Dana

I did setup Ricoh SIP-FAX as a Third-Party SIP Device per instruction but not registering to CUCM.



Thanks

Where is the gateway sending the INVITE? Is that going to the service provider or CUCM?

Here's a discussion on support forums regarding Ricoh SIP fax device.

Greetings! I have a number of Ricoh Multifunction Printers that support H.323/SIP IP-Fax capabilities. I would like to be able to use them with my CUCM 7.1 and 2821 ...




As long as it sends a re-invite for voice call -> fax escalation, and responds to invites for fax escalation, the calls will work fine.

I did turn on debug and made inbound call and see that gateway is sending 3 invite but not getting any response.



The other question is, has anyone configured any SIP FAX as 3rd party sip device in CUCM? Is that even capable.



thanks

Hamu

Check if the call is being answered first. The first step of a fax call is the voice call getting established, and then getting escalated to a fax call.

So usual troubleshooting for a voice call to see why the call is not answered.

The next step is to check what protocol of fax you are using and check if that is configured correctly end-to-end.

Hi Everyone,



Has any body experiencing configuring RICOH MP C5503  for SIP FAX on Either CUCM as 3th party SIP or on voice gateway?



11.0 CUCM

SIP FAX: RICOH MP C5503

Voice router 4431.



I have configured Route Pattern in CUCM and pointed the router group and then to the voice gateway.

I configured Dial peer in voice router but when I dial the FAX is not picking up. When I try to dial out, nothing is happening as well.



Dial Peer as shown below:

dial-peer voice 500 voip
 description Ricoh 072
 destination-pattern 10 digit #
 session protocol sipv2
 session target ipv4:x.x.x.x
 voice-class codec 1
 dtmf-relay rtp-nte
 no vad
!
dial-peer voice 501 voip
 description Ricoh 073
 destination-pattern 10 digit #
 session protocol sipv2
 session target ipv4:x.x.x.x
 voice-class codec 1
 dtmf-relay rtp-nte



I'm just wondering if I'm missing any configuration.



if you can point to the any document that I can follow to make sure everything is setup correctly, that would be appreciated.
