A bit of background, pre-query:
We have Obi boxes with Panasonic DECT phones & like that setup alot - we also use SIP via various softphones & Android as well, so SIP is not 100% foreign here, though I make no claims a'tall of being an expert either.
So - when the chance came 'round to grab a used KX-TGP550 SIP phone I grabbed it.
Beautiful phone set too, multi-line with very nice features.
Wanted to use its 1st line with GV so we got a Simonics Gateway account & found some info about setting it up & it worked OK - for a few hours only, then quit ringing for incoming calls - but could still make ougoing calls.
Later still Line #1 quit registering altogether anymore.
Line #1 is set up as per the info here:
http://support.simonics.com/support/discussions/topics/14878
Line #2 is set up with F9 and has worked fine since day 1 & is 100% working now.
Appealed for help via GVGW ticket & forum, and=>
Mr. Simon recommended changing the Keepalive to 300 or less seconds & to change to TCP transport instead of UDP.
Phone rebooted automatically after the 2nd change & it started working via GVGW again - but then F9 could not register. Woof.
Then it quit registering via GVGW altogether - no matter what & I cannot get it to work at all anymore.
All our other devices are working flawlessly & other SIP usages go through that same router without any problems.
Since then I've tried everything I could think of, slowly & methodically starting with changing the Transport Protocol back & forth between TCP & UDP - and that made no difference in the GVGW line; still would not register, whereas line 2 (via F9) is working perfectly again but ONLY via UDP rather than the TCP which GVGW is said to require...?
Problem is - UDP or TCP is a system-wide setting & anytime it is changed causes the system to re-boot - and since either line wants the other setting this is a real problem.
Ultimately Mr. Simon has simply repeated that his advice stands and offered no further help & I am now out of my depth & all out of ideas of what to try.
I also appealed to Nitzan of F9 for help as he always seems to be so very helpful, and he said:
"There is no way to use F9 via TCP, we support only the standard UDP.
I am not sure why Simonics doesn't, as this is the standard for VOIP
communications and works with any other provider (TCP only works
with very few)."
So:
I am hoping that someone here has also got a similar setup & knows what may be done to have both of these things working on this system, somehow ??
Thanks for any helpful replies.
