fax not receiving

[susim]

Hi

If  a user send fax from analog line (not all) , my fax server does not  receive fax from the voice router 

Below is the configuration 

dial-peer voice 306 voip
 destination-pattern 'number'
 session protocol sipv2
 session target ipv4:10.0.1.1:5062
 dtmf-relay rtp-nte
 codec g711ulaw
 fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco
 no vad
!

What does it mean by   

dtmf-relay rtp-nte

 codec g711ulaw

Do i need to change something on voice router 

Thanks

Hi,

It is hard to tell without the whole picture and debugs but here is a base dial-peer I always use for FAX, then I just tune it based on specifics on the environment:

dial-peer voice 3223642 voip
 description fax from pstn to FAX server
 preference 1
 destination-pattern <patter for FAX server>
 translate-outgoing called 82000
 session protocol sipv2
 session target ipv4:<ip of FAX server>
 session transport udp
 codec g711ulaw
 fax rate 14400
 fax protocol t38 ls-redundancy 2 hs-redundancy 0 fallback cisco

Must of the FAX servers I deal with are openText / Right FAX and provably CUCM in the middle, in such case just put the IP of the CUCM server instead of the FAX server.

Thanks Mr Nuche

Can you post the description of each commands or any helpful link.

"Must of the FAX servers I deal with are openText / Right FAX and provably CUCM in the middle, in such case just put the IP of the CUCM server instead of the FAX server."

If cucm is in the middle  , how you are connected to the fax server  ?. Is it sip trunk 

Thanks again
