Cisco SPA112 FXS

[Jimmy]

Has anyone gotten these to work behind remote NAT.

Hi once again,

Ive been playing around with the Cisco SPA112 FXS and I can get it to send t38 faxes and regular faxes via g711 with no problem.  But I cannot get it to receive.  What is weird is that when the ATA registers like 

<sip:202@xxx.xxx.xxx.xxx:5079;transport=tcp;x-sipX-privcontact=xxx.xxx.xxx.xxx%3A5079%3Btransport%3Dtcp>  faxes complete outgoing only ( xxx.xxx.xxx.xxx ) represents my public ip

but when it registers normally

<sip:202@xxx.xxx.xxx.xxx:5079;transport=tcp;x-sipX-privcontact=10.0.10.253%3A5079%3Btransport%3Dtcp>  voicemail picks up after it rings 10 times

I have the following enabled in the NAT Support Parameters on the Cisco SPA112 FXS

Handle VIA received: yes

Handle VIA rport: yes

Insert VIA received: yes

Insert VIA rport: no

Any guidance will greatly be appreciated..

The SPA2102 and 3102 is actually fully supported and configured by sipXcom and works well with Fax.  You might give it a try.

Got it to work.... a little unorthodox and weird but it works 100% @ 14.4k

<sip:202@xxx.xxx.xxx.xxx:5079;transport=tcp;x-sipX-privcontact=xxx.xxx.xxx.xxx%3A5079%3Btransport%3Dtcp>  

that's how it registers and faxes work both ways all the time... I increased the ringing time in sipxcom from 20 seconds to 35 seconds also.  Where should I post the config for anyone else that wants to use these devices behind a nat.  I can get them to work again flawlessly if they have there own public IP, with just entering the username and password in the config.

Question, did you happen to get this to work?

I'm trying to get a SPA112 to work with fax and having similar issues. Outbound works fine but inbound is failing for some reason.
