Wouldn't make sense to connect those two asterisk through SIP or IAX via Internet instead of calling via PSTN anyway?
Anyway, In this case it seems that this is not asterisk related, try the several Sipura/Linksys settings related to DTMF, also if the asterisk boxes are the only thing your ATA connects to, there is no point on using the "auto" mode. Check the "relaxed" dtmf setting on yhe linksys, and also check the Impedance, Rx and Tx gain, As well as the DTMF duration, All this "knobs" can mess up your DTMF tones if there is something wrong.
