I have a client who currently has an old Meridian PBX that has a DASS (G.703) connection to the PSTN with 9 channels. I wish to replace this with a 2821-CCME.
Does Cisco support PSTN connectivity with DASS/G.703 using CCME and a VWIC2-1MFT-G703? If so can you please point me to any configuration guides.
Thanks in advance,
You cannot support DASS on CME.
Whilst signalling converters are available from third parties such as Westell, they are expensive and not really worth the hassle.
You need to get the service upgraded to ISDN 30 / I.421.
