Hi, Asterisk: 1.8.4.2
I've just managed to configure attended transfers using Asterisk and Grandstream GXP-2000 phones. The only way I've got it to work is by using one of the out-of-band DTMF modes on the phone (either RFC or SIP-info).
I think I can understand why - as Asterisk wouldn't be "seeing" the DTMF tones during the call if they are inband (or am I wrong)? I have "canreinvite=no" in sip config so that all media goes through Asterisk. However, it is strange that none of the wiki pages on voip-info.org or comments in the features.conf file seem to mention anything about this. Am I missing something? Can features/transfers/call parking work with inband DTMF? Is it an issue particular to Grandstream phones?
Thanks, Sebastian -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
