Hello I have problems with TCP and GXP2000 phones. They work fine using UDP, but no calls arrive if I switch to TCP. I've upgraded to the latest GS firmware today to see it that helped, but it didn't. Have anyone else had problems with TCP? Regards, Jonas
Yeah, the GS don't work with TCP to any SIP PBX. I opened a ticket with GS and told them that their TCP implementation is broken and their answer was "use udp". It worked initially for me, but if I restarted FS, the GS never re-registered. Their TCP implementation is broken as the FS server sends back a RST since the port is no longer active and the GS just keeps trying to register on a bad port. The only fix is to reset the GS every time FS is restarted. Jonas Gauffin wrote:

I am sure you would need to reset the GS many times using UDP too :) If you use it extensively, that is. Peder @ NetworkOblivion wrote:

Only if you want them to hate you :) My experience has been that you can give GS to people who need the functionality but hardly use their phones- like executives. Operators/call centre agents/support people etc you might wanna hand a MUCH better phone. Polycom/Aastra are excellent choices. I've also had much success using Cisco 7911G Global Spares with SIP firmware. The Linksys SPA922/942 are also amazing phones. All these phones are about the same price as the GXP-2000. Its sad because the customer will blame Asterisk/Freeswitch for the phone hanging, distorted voice, random hangups, one way sound, etc when its ALL GS fault. The GXP-2020 is FAR worse. So is the GXV-3000. Budgetones are fine technically but pathetic to use. Jonas Gauffin wrote:

It's my experience that executives in Europe tend to have better or more high-end phones than the rest.

Imho Cisco is not an option. Their SIP firmware seems a 2nd class citizen as afaik Cisco primarily makes money selling CCM with SCCP phones. Silly things like the Supported header containing "(" and ")" characters in 8.3.5 SIP firmware is just an example why I avoid Cisco. And what about having to buy a SmartNet contract just so you can download new firmware that (hopefully) fixes bugs (and doesn't have new bugs). Think about it: paying for bug fixes.
The Linksys SPA922/942 are also amazing phones. All these phones are about the same price as the GXP-2000.
Afaik the Linksys phones don't support BLF (iirc the extender does). Since they are part of Cisco I won't go that route either.
Its sad because the customer will blame Asterisk/Freeswitch for the phone hanging, distorted voice, random hangups, one way sound, etc when its ALL GS fault.
Then don't sell your customer GS phones... Regards, Patrick
Once you figure out their little issues, they work pretty good. Don't bother contacting support for issues, it is probably the worst I have ever seen. Your best bet is to get a couple and try them out and see how they work for what you need. Jonas Gauffin wrote:

If you touch the account page after setting it up and registering with FS, FS will then deny registration. I suspect the password gets messed up. If you need to change the account settings you need to factory reset and get it all right with one pass.
