Re: [asterisk-users] low success rate for ReceiveFax
I have set the clock source from MASTER to NORMAL in the sangoma card
settings, and I'm still getting 3RD_T2_TIMEOUT error codes:

It's strange because I previously tested using another asterisk server to send fax using SIP to the receiving server above, and the completion rate is better than using an actual fax machine. With a direct PSTN connection like that a success rate of 99% should be considered very bad. The log below suggests you have hiccups on the audio, and the single commonest reason for that in a setup like yours is you are not sourcing the clock for your Sangoma card's E1 interface from the PSTN.
