Mobile extension doesnt disconnect?

Hello,

I have laid my hands on a Nokia E51, which registers nicely with PBXes. I set the extension parameters to "mobile" and "connection check".

I place a call using the Nokia handset, I get connected fine and call quality is great. Then when all is said, I want to hangup....
I press the red key on the phone... The other party will hear something like "please hold while I try to connect that extension" , then hears the on-hold-music... A few seconds later PBXes rings my Nokia... If I decline call, it will ring via GSM...

Any way to sort this?

RE: Mobile extension doesnt disconnect?

You can find out by disabling the handoff option. Is this always the same or do you get the music only sometimes?

Hello,

Thanks for the tip.

Weird. If I set connectioncheck off, the other party will not be put on hold (no music), and my Nokia does not get ringbacks after I hangup.

However: the other party does NOT get disconnected, he also has to hangup on his side...


If connectioncheck is on, I simply cannot disconnect: the red button always just puts the the other party on hold, and my phone will ring back several times. If on each ringback I deny the call (red button) sooner or later it will stop. But it takes 3-4 (have not yet counted) ringbacks, which is quite annoying...

RE: Mobile extension doesnt disconnect?

You are using the E51 with firmware version 100.34.20. We already had another customer with this release observing strange effects. I would recommend an update to 150.34.15.

Upon your advice I visited a Nokia service center. They upgraded my firmware, but it is the same version number as it was before the intervention... They say 100.34.20 is the latest fw version... Hmmm. My friend google tells me that the version you mention is not an official version and is Vodafone-specific???

I will try again if anything changed with this 2 hour service visit...

RE: Mobile extension doesnt disconnect?

The mentioned firmware for the E51 really seems to be broken. Besides the disconnection problem it has a problem receiving calls with mobile option turned off. This lead to complete hangups of the phone. Such hangups have not been observed with any other E series model.

The interesting thing is that after I took the phone to Nokia Service center for firmware update, there is no more "doesnt disconnect" issue, however, apparently the firmware itself is the same version.... I guess Nokia changed some software components on my unit to solve the issue, but it is not the firmware...

Everything went fine, until today (it may have happened a few days ago, but I only realized it today.)

Now if there is an incoming call to my Nokia extension, I immediately see on the phone that there was an incoming missed call.... The caller hears busy, and the PBXes log shows that my phone sent a "486 busy" signal.

Has there been a change at PBXes somewhere or something happened to my phone?

It must have been the phone... I restored a backup of a few minutes earlier to the phone and problem was gone... Don't ask me what caused the problem though... No idea.

Finally we found and corrected the bug. It appeared with port numbers other than 5060.
