I tried the to build/install the .tgz in the attachment above under MinGW/GCC 7.3, using the build steps as stated (after applying the patch). PTLib .configure'd, but the Make step crashed on "undefined reference to PPlugin_PVideoOutputDevice_Window_link()", though I suspect if it continued it would have crashed on other "PPlugin ..." bits that appear in the *.dtf MSVC files. ... PVideoOutputDevice seems to be an OPAL element, so not sure if I got the build order wrong. 1) Should that happen? I am...

I’m trying to send a fax with hylafax through t38. The port range is being specified as 5000-5399, but T38 packets are being sent out on 10000 and higher. Is the port range actually honored? In case I’m doing it wrong, what’s the correct way to specify it?

Hi, I've tried hard to setup an Asterisk PBX with T38modem, using Pete's current releases of ptlib, opan, and t38modem. The IAXmodem setup is doing fine so far, e.g.: T.30 setup: Modem <-> PSTN <-> SIP Trunk Provider <-> Asterisk <-> IAXModem <-> Hylafax: OK T.38 setup: Modem <-> PSTN <-> SIP Trunk Provider <-> Asterisk <-> T38Modem <-> Hylafax: FAIL Both directions are affected. The SIP Trunk Provider handles T.38 correctly. The modem is from an old ISDN based setup (Asterisk 1.2.31, Elsa Modem),...

In fact, i was searchning for same thing and also opened new thread for it. Just few minutes later i found the answer myself, while digging through some other threads. Outgoing caller ID can be set for each outbound call using L modifier in ATD command. I'v just tested that on my Hylafax install by putting that number directly into ATD command in modem config. The line in config looks like this: ModemDialCmd: ATDLT%s This of course is static, but Hylafax is immensely flexible, so we can use...

Oops, looks like it works. I haven't fully understand it at first when reading through ReadMe, but the L modifier in ATD command does exactly the thing. I've just tested it with success. So this solves my problem.

Hello, i have a SIP trunk to ISP's asterisk with various numbers allowed to be used as outgoing caller ID. Right now, a can set out. caller ID by using OPAL-Calling-Party-Name option in morem routing definition. However this is quite static. Is it possible to change outgoing caller ID using some AT command? Faxsend command of Hylafax server does some modem initialization before each outgoing call. It would be nice to have some AT command, which would set outgoing caller ID. Is this possible or no?...
