Mailing List Overview and Sign-up

The SIP Forum operates mailing lists for each of its working groups, as well as a general-purpose mailing list for questions about SIP.

Please note: As a SPAM control measure, all SIP Forum working group mailing list subscriptions (except the general SIP Query “discussion” mailing list) should be from an address (domain name) that has an obvious association with SIP and IP communications technology. As a result, addresses with a gmail, hotmail, yahoo or other free mail service domain may be rejected. Please subscribe under such an email address, or if this is not possible and you want to use a free-service domain, please send an email message to providing your organizational affiliation with IP communications. We hope you understand and appreciate our desire to keep spam from our lists, and will bear with this inconvenience.
