ITSP SIP Trunk CCA request #1: Via Public Internet

Dear Cisco UC500 team. Please can you create an XML template for SIP trunks via the Public Internet and our Public SBC's?

1. Please ensure that ephone-dn's, hunt groups etc  have "no reg  both" to avoid unnecessary SIP registration noise.

2. Please can you set DTMF relay to prefer RTP-NTE and then SIP-INFO

Kind regards

Voice CodecG.711ulawChoose one of the 3 codecs shown

it would be great if you could support a voice class containing the following:

voice class codec 1
codec preference 2 g729r8 bytes 40 (most efficient use of G729 for ATM based DSL)
codec preference 3 g729br8 bytes 40
codec preference 4 g711alaw
codec preference 5 g711ulaw

and that you create a transcoder, so calls make it OK to CUE, if not the only option would be to stick to uLaw.

Fax protocolT38Choose one of the 2 methods - T.38 or G.711 upspeed
RFC2833 (DTMF) payload type101Default value is 101, if change is required, then enter  value in range from 97 to 121
Should UC500 register all DIDs to ITSPnoTypically most ITSPs register only the main number but if  all numbers are required then choose YES
