[Freeswitch-users] Polycom Consultative Transfer and Voicemail

I get the idea, but can't seem to get it to work.

I tried doing a bridge to "loopback/app=bridge ${sofia_contact(${dialed_user}@${dialed_domain}", but fs complained => Cannot create outgoing channel of type [loopback=app:sofia]
Also, I tried "loopback/app=voicemail:default ${domain_name} ${dialed_extension}" and it did get to voicemail, but it didn't prompt me for any info - just immediately complained that the recording was too short.

I tried the suggestions about modifying the sip.cfg for the phones and that does work (thanks!), but that forces a Consultative Transfer.  It would be nice to get this method working, which would result in the transfer button doing a Consultive Transfer unless you hang up, then it would be like a blind transfer.

Thanks,
Troy
