Topic: Blind transfer with Aliases

[ldkeen]

Hey Jeff (again),
While I was in a typing mood I thought I throw this one down as well. I can't get the Blind Transfer option (#) to work with Aliases? I'm sure it used to work before. If I ring an extension from another extension the Blind Transfer function works perfectly BUT when I ring an Alias from an extension it doesn't work. When I push the # key on the dialpad (in fact any key) asterisk comes back with Packet2Packet bridging SIP/5005-08bcefe8 and SIP/5000-08bd0a20 and just ignores to tone. Here's the full output of what is going on:

 The transfer button on my GXP2000 works fine it's just the # key on the other phones that doesn't work. It's not a huge problem for me, I'm just trying to give a bit of feedback.
Many thanks,
Lloyd

Hi Mate

This is interesting and worth a word or two....

That # key is nasty nasty nasty.  Don't use it unless you have clunky old analogue units or phones that won't transfer any other way.  Instead, Use the nice SIP re-invite for everything. 

The reason alias groups don't respond to # is due to the dial we do... (from your trace)...

Code: [Select]

EXEC Dial SIP/5000&SIP/5003|30|wW
In a normal dial we do...

Code: [Select]

EXEC Dial SIP/5000|30|TtwW

The Tt tells Asterisk to accept # transfers (from both ends).  Now, I don't actually know why Sam disallows # transfer on Aliase group dials (I'll have to ask hm) but you can still transfer with a SIP reinvite (at least you can on the -587/1.4 test image we have here - I just tried it).

Best

Hi,

Did you asked Sam why # is disallowed on aliases ?

I should like to make transfers with an old analogic phone... Better if I'm not obliged to change this phone !

[SARK devs]

They are disallowed because they can crash asterisk in 1.4


Kind Regards

Hi,

Thanks for your reply !

Finally, I discovered that it's possible to use the 'R' key. It's not really the same, but it's a nice and useful workaround 

best regards.
