Settings using Polycom Phone

I am new to the SIP world. I tried to search for answers on this forum and elsewhere but am still stuck. Thank you in advance for your help.

My goal is simply to use PBXes in conjunction with Google Voice to have a reliable and good quality phone line through the Polycom IP 650 phone I have on my desk.

I originally stumbled into PBXes and registered through Sipdroid however I only have a minor interest in using the PBXes service through Sipdroid. My primary interest is using my Polycom desk phone and then secondarily a softphone client.

X-Lite 4 and Sipdroid seem to work okay for me but trying to use my Polycom phone had seen marginal functionality at best.

Out going calls on the Polycom work ok but every incoming call has failed for the last several days (since I signed up.) Incoming calls ring but when I try to answer on the Polycom the connection is never successful. My best guess is that I am using an incompatible codec setting because every call is ringing but upon answering every connection attempt fails. (Alternatively I can answer calls through softphone and sipdroid ok.)

My "Transport Settings" on the Polycom phone are: DNSnaptr, UDPonly, TCPpreferred, TCPonly, or TLS I believe I have tried each of these settings with the same unsuccessful result. I don't know which one is best but I would like HD Voice if possible.

A seperate question is can I be registered to my PBXes accounted on multiple devices at once? Ex: my polycom phone and a softphone client at the same time.

I would certainly appreciate any help in getting my phone configured or perhaps a link to the right information source. Thank you!

RE: Settings using Polycom Phone

I know this is an old thread, but I'm having the same/similar problem.

Outbound calls from my Polycom IP550 (running SIP 3.2.5) work just fine using the Google Voice trunk.

Inbound calls over the GV trunk ring to the Polycom phone, but I cannot answer it. (It just keeps ringing if I pick up the handset or hit the answer key.)

I've turning on G.722, but other than that I have a default setup.

I can answer calls on an X-lite softphone registering to a different extension on my PBXes account.

A workaround I found is that I signed up for a free sipgate.com account for free incoming sip calls. Set that up as a trunk in PBXes and set GV to forward to my sipgate number and not GV.

I.E. I can answer incoming calls from the Polycom just fine when they come in over a SIP trunk rather than a GV trunk.

(It would be nice to be able to use the GV trunk directly, since then I could use Google Chat receive calls rather than having to keep the softphone running while I am away from my desk.)


EDIT: Upon further testing GV was seeming to have intermittent problems connecting calls in general. Restarting my account did not help, but I changed my preferences from the newest software to "stable" software, and moved from the www4 server to www2 and all of the problems seem to be resolved. (I can now answer calls coming in on the GV trunk on my Polycom phone.)
