MGCP Gateway freezes

Hi I have a 2651 MGCP gateway connected via Qsig to a Siemens ISDX working with CCM 4.13(sr2). My problem is that only the first 15 channels on the PRI are being used on calls. every now and then channel 16 is used and freezes the gateway. this has made my system unusable. I really need all 30 channels working. any ideas?

Re: MGCP Gateway freezes

You mention that the first 15 channels are being used for calls. On an E1 PRI, isn't channel 15 the D-channel?

Edit: The more I think about it, the sillier I think my line of thinking is getting. I was first wondering if there was a mismatch, of sorts, with the D-channel so that one side periodically tried to use the D-channel as a B-channel. However, that would break everything--no calls would work.

Still, it's interesting that every channel up to the D-channel is working, but calls on channels above the d-channel fail. Does one side think this is a fractional E1?
