Hi, I have some question!

does VP530 support Call-Info and Alert-Info(RFC 3261)?

I Checked Alert-Info Operation, when i call to VP530 including Alert-Info Header, VP530 Download my wav file..but it doesn't play my wav file...does it need a specific format?

if VP530 doesn't support Call-Info and Alert-Info, please tell me which model support Call-Info and Alert-Info

thanks for your information

for the RFC3216, VP530 can support it , but for the alter-info of distinctive ringtone , VP530 will not support

other models like SIP-T48G , SIP-T46G , SIP-T42G , SIP-T41P ,etc. can support it , for more details , you can refer to the FAQ :
