E72 Sip Connectivity and performance

Hi,

I'm not too terribly tech savvy, but was able to set up SIP calling from my E72. But the service isn't working as well as it seems to be for others. I have two problems.

1. Call hand off (or just connectivity) between wifi and cellular data coverage. Right now if I move out of my home wifi zone I later discover that my phone is no longer registered to my voip service. In settings it's supposed to be "always on" but I don't even seem to be getting a prompt that tells me that the connection has dropped.

2. Freeze ups or dropped calls. I've maybe made and received 10 calls so far, and while the quality is always excellent, a few calls have dropped suddenly and just now the calls have been making my E72 freeze up. In one case I had to remove the battery, in another case I had to force close a number of apps because the phone got so slow.

Have I misconfigured something? Anyone having a similar problem? I am using voip.ms as my provider.
 
I don't have an explanation for 2.

But for 1.:
I know that the hand-off (for a non-active call, just the SIP phone registration) between two different WLANs works thanks to this setting:
Show WLAN availability (choose YES) and Scan for networks (I have it set on Every 5 minutes).
I don't know of a way to insure that that this gets handled properly between WLAN and UMTS.
 
Wirelessly posted (Nokia N95-3: Mozilla/5.0 (SymbianOS/9.4; Series60/5.0 NokiaN97-3/21.2.045; Profile/MIDP-2.1 Configuration/CLDC-1.1) AppleWebKit/525 (KHTML, like Gecko) BrowserNG/7.1.4)

for sip the handoff doesnt happen between wifi and umts.
 
Since you are both interested in/ know about VoIP and the Nokia built-in SIP client, I'd like to propose we come-up with a write-up to receive free incoming and place free outgoing calls via Google Voice on the E72 via a data connection.

Usually the set-up goes like this: GV > ipKall > SIP Sorcery > Nokia E72

The search results I have found so far did not help me as they were not specific to the Nokia SIP client.
 
I've been able to get Voip over 3G by setting AWCDMA to "on".

Find it by going to Advanced Settings > Voip Services > (your voip provider) > Profile Setting.

I tested a few calls all from the same spot. I could hear the person very well but on the other end the call would stutter occasionally (subjective call quality of 7-8 out of 10).
