[asterisk-users] Fax issue over cisco gateway

[Enrico Pasqualotto]

Hi all, I'm trying to send fax from Hylafax to a remote fax machine
through Asterisk and cisco 2801 as E1 gateway.
This is my architecture:

sendfax -> HylaFax -> iaxmodem -> Asterisk -> (SIP) 2801 with E1 card 

For incoming fax I don't have any problem, but I'm not able to send fax
out of 2801.

My router conf: 
################
dial-peer voice 1 pots
 destination-pattern .T
 fax rate disable
 port 0/2/0:15
!
dial-peer voice 3 pots
 incoming called-number 53T
 fax rate disable
 direct-inward-dial
 forward-digits all
!

In asterisk console I see a lot of RTP packets lost:

  RTP-stats-003*CLI> 
* Our Receiver:
  SSRC:		 642188040
  Received packets: 17463
  Lost packets:	 19686
  Jitter:		 0.0000
  Transit:		 0.0000
  RR-count:	 0
* Our Sender:
  SSRC:		 1469234407
  Sent packets:	 27926
  Lost packets:	 0
  Jitter:		 0
  SR-count:	 112
  RTT:		 0.000000

Anyone have idea of this problem? The packet lost quantity is normal?

Thanks Enrico.
