Intermittent problems with 3StarsNet

Hi,
I've recently upgraded to a SoHo account from a free account, but am having intermittent problems with our provider 3StarsNet (which happens to be one of the recommended providers by PBXes).

At certain moments throughout the day, we're getting a series of calls with no audio. Registering the ATA (Siemens C470IP) directly with 3StarsNet seems to always work.

I've looked at the log file for one of the calls for which no audio was receive and here is an excerpt (not sure if this helps):

Dec 14 15:20:44 VERBOSE[96459] logger.c: Adding codec 0x2 (gsm) to SDP

Please help as this is a critical problem.

******UPDATE*******

I have requested 3StarsNet to forward all calls to sip:myaccount@pbxes.org and this seems to have worked around the problem.

However, this means that I will not feel comfortable using third party SIP registrations in the future.
