OK, there could be a few items here:
1 Faxes usually do not work over straight IP. I know they can and many including myself have had success the mechanics of the IP network usually won't allow it. 2 If you are using anything other than a/u law forget it. 3 What is the connectivity between the Asterisk boxes? If they are plugged into the same private backbone (ie Same Ethernet network) you have a fighting chance. If not, it is up to the Gods of Network congestion. 4 You may want to read up on the IAXModem pages, Mr, Underwood, explains the use of IAXModem and gives a few pointers on useing the IAXModem to terminal/originate calls on the same machine that has the TDM circuits and use remote serial to bring the fax data back to the hylafax machine.

I need to send Faxes from an Asterisk box to an Asterisk + Iaxmodem + Hylafax installed on other box. I have setup IAX trunks between this boxes, all works fine but can´t send faxes from one to other, Im trying with or without NVFaxDetect application but does not work. Is there a way to get it working?. If I connect a fax machine directly to Asterisk with Iaxmodem and Hylafax, I have no problem. But between Iax Trunks nothing happened and the fax machine registered on the first PBX give me a communication error. Thanks for any help or idea to setup and get it working. Gustavo A.
