We have two ADSL connections into one router which can prioritise traffic based on port numbers and/or dedicate one of the ADSL connections to the SIP data.
However, both connections are only 8 Mbps download and about 0.75 Mbps upload.
We'd like to use Sipgate's "Sipgate Team" product to have 8 to 10 users, so upto 10 SIP phones (something like the Snom 320 handset).
I don't imagine that more than 4 or 5 users would ever actually be using the phone at the same time.
Does anyone have experience of having so many VoIP phones on such a relatively poor connection? Is it likely to work? Anything we can look out for that might give us problems?
