Interesting transfer problem with cisco 7941

[Rtreacy]

Hey Guys,

I finally got my Cisco 7941 to work with sip and 3cx.. The only problem is that it does not transfer calls properly.

1st: All blind transfers always fail.

13:49:59.859 CallStrategy::Transfer Call(C:8): transfer failed
13:49:59.859 StratTransfer::initialize Call(C:8): Cannot build transfer target by DBCfg

2nd: When I am attending a transfer, i meet the new extension and then i press transfer and I get the following error:

14:13:17.765 StratLink:nHangUp Call(C:17): HangUp from wrong leg has arrived. Leg will be removed from call
14:13:17.750 StratTransfer::finishTransfer Call(C:17): Transfer finished, Ln:10000@Blueface is connected to Ext.105
14:13:17.515 StratLink::Transfer Call(C:17): transfers Ln:10000@Blueface from Ext.100 to sip:[email protected]


The phone that I transferred to says that it has been placed on hold by the transferring extension.. and never connects to the party that is being transferred... UNLESS that phone places the line on hold and then resumes the call it is then connected properly... Any ideas anyone?? The phone transfers fine with Asterisk so I wonder if this is a system thing?
(if anyone notices the weird ip range, I tried a standard private range and it still doesn't work!)

This is the only thing stopping me from migrating i think..

Hi,

Try to uncheck "Supports 'Replaces' header" in advanced configuration. If it will continue to don't work then uncheck "Supports Re-Invite" as well.
Please notify which setting did force device to work correct.

Thank you,

Stepan

Hi Stephan, thanks for the reply!

The 2nd issue: the CP 7491 actually turned out not to be the cause of this.. it was due to the softphone I was transferring to, which was the X-Ten, X-LITE softphone. The CP-7491 transfers to outside lines and a different softphone just fine. This has given me enough confidence to buy a second CP-7491.

1st problem still remains. I cannot do unattended transfers!!

Hi,

I use different equipment, but I managed to remedy my Blind transfers by changing setting in the extension properties.

In extension properties, expand "Other" and set the SIP ID to the same as the extension number.

This fixed blind transfers for external (PSTN sourced) calls via my GXW-4104 and BT200's. It might help you as well.

However, I cannot do attended transfers! (for externally sourced calls only - internal extension transfers work fine)

Ok.. I have lost about 3mm of hair line over this..

Question: Can anyone transfer a cisco 7941 to the 3cx soft phone?
I have turned off supports reinvite and replaces header on all extensions.

What happens to me:
No matter what I trasfer to (external phone number, 3cx softphone):I have a call on my cisco 7941
I press transfer
I dial the new extension number, new extension answers
I press transfer to connect the call to the new extension.

Ok, sounds fine so far, but here is the weird part:

Transferred call hears the new extension fine. But the new extension hears the hold music.

So annoying. I thought I had it working.
Logs dont show anything unusual. Any help would be really appreciated

I get a similar thing on a 7960 the softphone (X-Lite) can just hear the music on hold

What version of the SIP flash are you using, Did you get it from cisco direct? I ask because I had a similar problem where I tried a flash that I found from google, worked fine, except for a few bugs, after which I tried the cisco firware, and it worked like a charm, I do still have it, if interested PM me and I can email it to you.

 

[Wardy]

I can't remember where the FW was from but probably not from Cisco

 

[Rtreacy]

I'm using SIP41.8-2-2SR1S from cisco. The phone seems to work fine with asterisk..

Ok, well a couple things to try, Restarting the 3CX server for starters. I have noticed with my Cisco 7940/7960's that they don't like to be unplugged and plugged back into the server with it running. Alot of wierd things will start happening.

Another thing, link your SIP000AF44FF097.cnf file.

Hi Stepan,

I tried this recently with a Cisco 7965G handset which doesn't have the Blind Xfer soft key on the screen and couldn't get blind transfers initially working until I took a look through this post. I tried switching off and on both settings you litsed above for the extension - no change.

I did, however notice that when I changed the extension to "use phone status" for it's busy setting blind transfers started working for me (which is good news).

The process for a Cisco handset without the Blind Xfer softkey would be to select the Transfer soft key whilst on the call, dial the extension you wish to forward the call to, then when you hear it start rining, press the Transfer button again. The only difference now between blind and attended transfers on the later Cisco handsets is when you hit the Transfer button the second time - before or after the received picks up.

Cheers, Brendan
