development of SIP at APAN member sites.

conducted which seeded the initial interest amoung
members.

the key goals of the group.

Nimal presented on the APAN SIP server.
Server is currently hosted at APAN-JP. Thanks to APAN NOC for providing this resources.
FreeBSD 6.2, IPV4 and V6 connects (2001:200:901:2::20). OpenSER.

Which media server (eg. SEMS, Asterisk)
Is peering or PABX functions more important?
Access control ?
Who should have control of there server ?
Conclusion:
1. OpenSER will be used as the SIP server.
2. Initialially the focus will be on peering rather than media/PABX functions.
3. Change control will be managed by submission for proposals.
4. Peering activities will be co-ordinated through the mailing list.
