Hello, The company I work for recently purchased 2 Rhino CB24s and a Rhino PCI-E R4T1. The channel banks are plugged into the R4T1, as well as 2 PRIs from our telco. The CB24s are for all internal analog phones. Most of the phones are setup in "batphone mode", which is "immediate=on" in the DAHDI config. They are set up this way because we are an outgoing call center, and the context that the batphones go to a database table to pull the phone number they are calling. Along with this new hardware, we changed to a new "server" (just a Dell E520 workstation with 4 gigs of RAM and 2 250 gig SATA drives software RAIDed) with the following software: Ubuntu 9.04 Asterisk 1.6.1.4 Asterisk-addons 1.6.1.1 (for the cdr-mysql plugin) dahdi-linux-complete 2.2.0.2 + 2.2.0 libpri 1.4.10.1 rhino drivers 0.99.2 Since day one, all batphones have had a weird noise at the very beginning of the call. I contacted Rhino about it and the support tech told me that it's "fsk" tones that have caller ID and MWI information and advised me to turn off advanced features like mailboxes. The phones already didn't have mailboxes, but I put in "mwisendtype=nofsk" in chan_dahdi.conf anyway, and all features like faxdetect and transfer are turned off. Has anyone else experienced this issue and fixed it? Thanks. Jason Martin Metrix Matrix, Inc. 785 Elmgrove Rd, Bldg 1 Rochester, NY 14624 Office: 888-865-0065 x202 Mobile: 585-705-1400

(This is usually transmitted between the first and second rings.) You should be able to set usecallerid=no in chan_dahdi.conf to disable the sending of the caller id fsk spill. Regards Doug Bailey
