Description:When the user presses "#" and transfers to the Parking extension, all is fine.  If the user attempts to use the "Transfer" button on the SIP phone, the result is always a congestion tone.  The extension is not read back and nothing happens.


This is on Polycom IP500 phones and happens regardless of the caller type.

Ok let me take a moment to repeat this.

I've added preliminary support for transfer to parking extension with SIP.  It doesn't appear to work right on the SNOM but that apeears to be a problem with the SNOM (or a different interpretation of the REFER).  You can let me know if it works with your IP500.

I can't get the sip parking to work with attended transfers.. just blind.. then you have to make a guess where the call went.

It will never work with an attended transfer, but with a blind transfer you *should* still hear the announcement unless your phone is assuming that there will be no audio after it sends the REFER and after we send 202 Accepted.

Now, if that's the case, one option is to delay the sending of 202 Accepted.  I wonder if we're allowed to do a 100 Trying on a REFER...

By: Mark Spencer (markster) 2004-07-09 17:57:23

Ooh!  Ooh!  RFC3515 says we *can* send 100 Trying on REFER!  I'll try to get my snom up and running to test this theory.

ChadScott: Please confirm wheather Mark's patch improved your situation or if it's still a problem with the PolyCom IP500. Thank you for a quick reply!

Actually, no... I'm having a secondary problem where the parking extension does not seem to be properly registered in the configured context and I therefore can't call it.

I'm still investigating that issue... once I can resolve that, I'll test this.

Be sure you have the "parkedcalls" context included in the appropriate context.
