Yes, we'll have incoming calls as well. I did not performed any tests
myself yet, but a guy working with this soft-switch says it just
rejects second call. So soft-switch treats each sip registration more
or less like single phone line. Soft-switch is Huawei SoftX3000, if
somebody experienced in it can prove me wrong, I'll be glad.. :)

Yes, that was my initial thought too - that this limit should be
configurable. But a guy working with it says it is not configurable,
and local support engineers from Huawei also confirm this. But, who
knows, may be they are all wrong.
