As per my (numerous) prior statements on this subject.... Asterisk WILL NOT properly work with the spa-3000 DTMF in rfc2833. Use INBAND when dealing with Asterisk on both the FXO/FXS ports of the spa3k if you are dealing with Asterisk. This is a setting in BOTH sip.conf and spa3k pstn and line 1 tabs.
Symptoms are no DTMF after call completion (voicemail from outside to fxo) and IVR attempts from FXS attached analog phones. Using INFO negates use of dtmf control functions on your fxs/fxo ports - transfer etc. - Take your pick of what is more important to you. There should really be a wiki on this! It gets asked often. I might qualify that this is an issue with 1.2.x (and probably earlier) - not sure if any fixes make this work or work better in 1.4. Fault (apparently) lies with both sipura(linksys) and digium. Since in this case you are connecting the spa3k's thru Asterisk this would apply. I have not tried connecting two spa3k's directly together via network to see if they play together in this regard.
