Dear Users

 I have 2 problems :
 i try to send a fax using 2 UA's and a Panasonic FAX machine, and it fail
the UA's support fax , so my providers says the fax machines need to support T.38 protocol , so the fax can be succesfully......
and ai saw my faxes are panasonic and don't have these features, how can i fix this problem ?? or how  is the procedure to send a fax , and wich features the fax machine must have ???

second i been triybg to use SER to call outside , in a NAT environment
UA( SIPURA or ATA )------ADSL-NAT..-----SER---------UA, so when  the call goes, it begin to eat all the bandwith in the ADSL modem, and a error cames thousand times into the modem log
"limit por : SIP port exceed ". so i can't call clearly.....and is imposible to begin a second call
