1) On SPA112 set "FAX T38 Redundancy" = 3
I have tried to change this value with no effect.
2) Add t38pt_usertpsource=yes in [mtt] section
This option take no positive effect for me, asterisk continues to use
ports from udptl.conf range. But in the oser side, I think, that there
are no problems with network, because:
* on router, that provide internet for asterisk configured full DNAT
from white IP to asterisk server,
* fax between asterisk cmd SendFax and PSTN fax works great.
3) Change maxdatagram=200 to maxdatagram=1400
4) In udptl.conf change T38FaxMaxDatagram to a value of 1400
5) In udptl.conf change use_even_ports to yes
This settings doesnt help me.
You don't appear to list the sip.conf entry for the SPA112.
I`m sorry, spa112 peer settings are in mysql extconfig, config file
analogue:
[297]
context=office
secret=xxx
host-dynamic
nat=yes
type=friend
callerid=297
disallow=all
allow=alaw
Where did t38pt_rtp & t38_tcp come from?
This settings I have googled on some forum and then add to my config
with despair.
You may also want to experiment with the SPA112 setting "FAX T38 ECM
Enable"
This option doesnt help me too :(.
Additional info: fax between two SPA112 works perfect! Now I returned
settings to original state as described in first letter.
