Colleagues,
The H.GCP audio call was held Thursday March 4th , 18 ports called in including a group from the TIPHON meeting. Companies represented were ATT, Lucent, ACGS, RadVision, Cisco, Nortel, Delta Information Systems, NetSpeak, Bellcore and others. . . The meeting opened by reviewing a proposed working model and fleshing out the work items that need to be addressed. A number of individuals committed to fleshing some of the work items prior to the next call, I would like to thank these individuals in advance. There was some news from TIPHON regarding changes to the reference model and some adjustments to the requirements they have contributed to H.GCP. These changes will be reflected once TDs from the Philadelphia meeting are released. The last hour or so was focussed on reviewing the H.GCP requirements I sent around prior to the meeting. The next call is tentatively planned for Thursday March 18 at 10AM EST.
The working model Individuals will be working up submissions to be reviewed by the entire group at the next audio call. The objective is that the principals involved will collaborate off line initially, post the results to the SG16 reflector for comments and a final version will be posted for discussion in an audio call. The result of that final review will be added into the H.GCP by the editor. Every effort will be made to resolve issues in this forum but if issues remain they will be logged and discussed in Santiago

Colleagues,
I would like to invite you to participate in audio call on Thursday March 4th from 11AM until 1PM EST to discuss H.GCP. The call details are as follows:
Calls from outside the US: 312-470-7273 Calls from within the US: 888-847-7598 Passcode: BryanHill Confirmation number: 5193957
Please respond to me directly to reserve a port for this call (where ever possible please try to minimize port requirements by sharing a port with a colleague).
The main purpose of this initial call will be to review requirements and terminology for H.GCP which were discussed in Monterey. I have been editing these sections and will make them available on the ptel SG16 ftp site no later than tomorrow 3/2. The second purpose of the call is to identify other areas that need to be discussed in subsequent audio calls. An initial pass of topics is listed below. I would like to solicit volunteers to submit written contribution in each of the areas identified and use these submissions as a basis for discussing topics in future audio calls. In this manner I hope to scope our discussion to specific technical topics and combine the benefits from MDCP and MGCP approaches into H.GCP.
1) Control model a) Controller to gateway associations b) Controller to internal gateway entity associations c) Failover d) Security 2) Connection model a) Controllable entities b) Controllable entity properties 3) Commands a) Types b) Parameters c) Acknowledgement styles/sequencing 4) Messages (i.e.-command packaging) 5) Message Encoding 6) Resource management 7) Scripting/Packages 8) Interface C protocol (Q.931/Q.764) 9) Interface B protocol (Q.931 )
