I'm not familiar with sipcall but I assume they're providing a hosted PBX service to you, so yes they are the ones you need to talk to. Yes it's entirely possible for them to have done something that would break call transfers but let other things work properly.

For example a few years ago there we ran into a customer who had their phones connected to a SNOM system. Everything worked fine, and then one day the system did an automatic update and they could no longer transfer or forward calls. Turned out it was a bug in the system update, and it took 18 months for SNOM to finally admit it and issue a patch to fix it. Not saying that's the case here at all, but just providing an example of what can happen as nothing (especially with hosted PBX) is set in stone.
