Fortunately I found one very good implementation of SIP ALG. It is linksys wireless router WRT54G with the latest firmware. This sub-$100 router
Hi Richard,
We have deployed quite a few WRT54G routers with firmware based on 2.07.1 (by Sveasoft) which as far as I can tell is the latest posted by Linksys. We use them because we can run traffic shaping on them which is absolutely necessary when we install our SIP devices in small businesses. However we have not seen any evidence of a SIP ALG on them. Can you tell me on which firmware you saw this?
Thanks,
