Steve:
This means the only way to use Transfer (or Hook and DTMFSend) in a E1 is using it as a channel bank trunk using FXO signaling?. I really need to free those channels.
I'm glad the outgoing problem will be solved soon. If Transfer don't work, it's the only way to call the operator via a second channel.
BTW, I'm in Argentina using the local R2 variant against a Meridian 1 Option 11C via a DTI2 card, Asterisk is using a 410P card in E1 mode.

Hi Guillermo,

It's possible to use the "Transfer" function in UniCall MFC/R2 lines?. The command seems to do nothing when called from a R2 call, but it works fine from a SIP phone. Transfer and 3waycalling options are set to "Yes" in unicall.conf. I've tried the "hook" command but it didn't work either.
I need to make a blind transfer from a incoming line of our R2-connected PBX to another extension in the PBX, to not to waste 2 channels in a second Dial command.
Also I'm having trouble with outgoing calls generated in Asterisk to the PBX via the R2 line. The call hangs after a couple of seconds if answered in the first ring, or dies after the first ring if unnattended, and the channel remains in "Call" state in asterisk. Any indea?. Incoming calls work ok.


Guillermo

It is good to hear you are getting some success with my R2 code.

R2 does not allow transfers of that kind. It is a protocol limitation, not something about my implementation. You cannot free up the circuits. In general, only the modern common channel message oriented protocols, like ISDN and SS7, can do that.

The outgoing call problem has been reported already. The will be a fix in a few days for that, and some polishing.

Which country are you in? I am trying to find which national variants of the R2 protocol are being tested.

Regards,
Steve
