I may be implementing a voice over frame solution in a few weeks and have started getting up to speed on this stuff. I have been going through many of the Cisco docs but I have not seen any scenarios similar to mine. My future setup will be this. A central site 3640 connected to a PBX and 6 remote locations with a Cisco1750-2v. Each remote soho office will have only one phone connected to the FXS interface. -------Cisco1750-2v With one phone connected ------Cisco1750-2v With one phone connected pbx --->Cisco3640-----Frame Relay Wan ------Cisco1750-2v With one phone connected -------Cisco1750-2v With one phone connected -------Cisco1750-2v With one phone connected I have an unused Pri port in the Cisco3640 already. The PBX is a Northern PBX with a Pri T1 interface. I am willing to purchase the t1/e1 multiflex Voice card for the cisco3640 if it makes things easier. Tell me which card is easier to configure? I basically want to pass dial tone from the pbx to the remote locations. I want the remote location phones to look like OPX lines. Can this be done? Any help or sample configs will be appreciated. -- John Gesualdi The Providence Journal Company Phone (401)277-8133 Pager (401)785-6938 CCDP,CCNP ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
