We are having problems using a postage meter in a new SIP trunk deployment. The ATA 186 has a line that is shared by a fax machine and a Pitney Bowes DM100i postage meter. Faxes are mostly working fine - we turned down the baud rate to 9600 and turned off ECM, but the postage meter will not complete its negotiation. PB support either can't or won't tell me what the baud rate is on the meter, nor whether or not it can be adjusted. Someone had to take it home to upload the postage last week. Not a good solution going forward. We are really interested in working out the bugs in this deployment as the SIP trunk could help us save some money. Any ideas or suggestions? Thanks.
