7 digit and 10 digit dialing

[Todd Bruner]

A reviewer on Amazon stated the following:

" In theory the 320w can support both SIP and analog lines, with one big limitation. BOTH SIP AND ANALOG LINES MUST SUPPORT 10 DIGIT DIALING, EVEN FOR LOCAL CALLS. Analog and SIP lines must use the same dial plan! AT&T POTS lines do not support 10 digit dialing of local numbers, SIP providers require ten digits. Hence I can't add SIP lines unless I replace all our POTS lines."

Is this true?  My concern is that in our location, the analog lines use 7 digit dialing.  This could be a show stopper if true.

Hi Todd,

UC320W supports 7-digit dialing plan as long as you provide the default area code in the configuration, so that UC320W uses 7-digit dialing plan for POTS line and automatically prepend the default area code for the SIP trunk call, the user only needs to dial 7 digits for the local call.

Hope it helps.

Best regards,

Wendy
