Dear list, I've got the following setup :
[FAX-ATA]--[PBX LAN]--[Firewall]--[PBX WAN]-----[upstream SIP] On the PBX's we run Asterisk 1.4.33 with t38pt_udptl=yes in [general]. The FAX ATA is a Teles VoIPBox with T.38 support (that works). On the PBX WAN, i see the following in udptl debug : Sent UDPTL packet to 172.16.0.156:4460 (type 0, seq 184, len 32) Got UDPTL packet from 62.180.xx.xx:36170 (type 0, seq 0, len 32) Sent UDPTL packet to 172.16.0.156:4460 (type 0, seq 185, len 32) Got UDPTL packet from 62.180.xx.xx:36170 (type 0, seq 0, len 32) Sent UDPTL packet to 172.16.0.156:4460 (type 0, seq 186, len 32) Got UDPTL packet from 62.180.xx.xx:36170 (type 0, seq 0, len 29) This means my outgoing udptl traffic is correctly translated, but somehow i'm sending 172.16.0.156 instead of my public IP address on the firewall. On the LAN PBX, i've got the following config : [general] t38pt_udptl=yes [202] type=friend secret=*** username=202 regexten=202 host=dynamic canreinvite=yes allow=alaw context=local qualify=yes On the WAN PBX, the config for the trunk is the following : [general] t38pt_udptl=yes [trunk] type=peer context=trunk-in host=62.180.xxx.xxx port=5070 disallow=all allow=alaw allow=ulaw qualify=yes nat=no Can anybody tell me how to change this behaviour? Fax isn't working ofcourse. -- Kind regards, Signet bv Remco Bressers T 040 - 707 4 907 F 040 - 707 4 909 E rbress...@signet.nl -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
