Without such a distortion machine V.17 should be fine.Read the subject line more closely. Tested receiving too,I set the Send & Receive speed of the receiving analogue modem to that below, the log file on the sending modem (iaxmodem) reported it capable of 9600.May 16 21:32:04.28: [ 2335]: REMOTE best rate 9600 bit/s May 16 21:32:04.28: [ 2335]: REMOTE max A3 page width (303 mm) May 16 21:32:04.28: [ 2335]: REMOTE max unlimited page length May 16 21:32:04.28: [ 2335]: REMOTE best vres R16 x 15.4 line/mm May 16 21:32:04.28: [ 2335]: REMOTE format support: MH, MR, MMR May 16 21:32:04.28: [ 2335]: REMOTE supports T.30 Annex A, 256-byte ECM May 16 21:32:04.28: [ 2335]: REMOTE best 0 ms/scanline May 16 21:32:04.28: [ 2335]: USE 9600 bit/s Perhaps the issue is with Hylafax.Setting the Transmit & Receive strings to "!24,48,72,96" seems to yield the most reliability in transmission
The receiving analogue modem is directly connected to the PSTN network and was used to to determine if the reported issue could be reproduced on a non-iaxmodem.
My outgoing connections were through an iaxmodem with T.38 gateway enabled and disabled, with most successful transmissions being when T.38 gateway was used.
