You are correct that Callcentric has a problem with initiating call transfers (at least with NCH software). I'm not sure of the exact reason, although NCH says it's due to a bug in Callcentric's system.
This is the first time I'm announcing this to anyone, but I am in the process right now of starting up my own affordable VoIP service. I plan on letting people from these forums have a chance to test the system out before anyone else does to make sure it's fully compatible with all of NCH's software (which I want to make a priority).
My aim is to have:
- Full compatibility with call transfers (blind & confirmed) for NCH software
- Ability to pick your outbound Caller ID number (since Axon lacks a feature to set one)
Other planned services/features:
- Affordable outgoing call prices for business and residential users (e.g. 2c/min to anywhere in the USA or Canada, great international rates)
- Incoming local numbers with unlimited channels (simultaneous calls) for as low as $4 a month plus usage (numbers available for all over the world)
- Toll Free numbers available for many countries around the world (including USA, Canada, UK & Australia) starting at just $4 a month plus 4c/min incoming
- e911 support for emergency services (USA)
- Online control panel to manage your VoIP account
- Support for: G.711 ulaw/alaw, G.726, G.723, G.729a, iLBC and gsm codecs
- Standard extra call features (including voice mail, call waiting, etc.)
- Unlimited outbound channels
Let me know if you're interested.
