If the requirements for the pre-MIDCOM solution would have been known, it would provide a baseline to compare all competing solutions.

All, 

Perhaps the reason we have not been making much progress on a pre-midcom solution is 
that we have not been discussuing how the candidates meet any underlying requirements. 
In truth we have no explicit requirements, only goals. However, at an adhoc meeting 
at the 51st IETF in London (in which 60+ people attended), there seemed to be a consensus 
(at the time only 1 person voiced disagreement) that a pre-midcom solution should address 
the following requirements: 

1. enable VoIP and MoIP through already deployed firewalls and NATs - no upgrades required 
2. protocol agnostic solution - work for SIP, Megaco, H.323, MGCP etc. 
3. must be secure in the firewall sense 
4. must keep control with the FW/IT administrator (i.e. if he wants to block VoIP, then so be it) 
5. should work with any flavours of NAT 
6. must allow existing clients/proxies to be unaware of the solution 
7. must be compatible with real-time media transport requirements 
8. a near term development without inhibiting long term solutions (Midcom/IPV6) 
9. not break end-to-end security 

In addition, the following are stated pre-midcom goals: 
a. rapid delivery 
b. consistency with midcom 
c. consistency with security
