a) The gateway will register all 4 ports if you're not using password.
b) If using password, the gateway will only register the 1st port correctly.

yes, and this is why, as i posted a week back:

i think i've nailed it down to the fact that the 3504A (firmware 107a) uses the same SIP Call-ID but changes the tag= parameter in the From header when it responds to the 407 Proxy Authentication response from asterisk, thus leaving asterisk with no way to match the REGISTER packet with auth credentials against the original REGISTER packet sent by the 3504A. based on my reading of RFC3261, this violates the RFC, but perhaps someone with better SIP kung fu could chip in to correct me if otherwise.

essentially, by not keeping to the same Call-ID or tag, asterisk has no way of matching the wellgate's register with the past proxy auth packet (and thus the hashed md5 token).

this has been reported to WellTech, but we've yet to get a response from them.

i've fashioned a patch which solves this behaviour and it works fine under asterisk 0.9.0 on freebsd and 1.0-RC1 on linux.

i've got the patches for 0.9.0 and 1.0-RC1, and will be glad to email them if anyone wants them. the patch adds a new option under [general], 'usenonce'. if usenonce=yes (default is no, normal asterisk behaviour), then asterisk will use the nonce tag as sent by the wellgate to double check it's credentials and let it thru. this allows all 4 ports on the 3504A to be registered with a password.
