I have a client who has just purchased 4 of the above phones from Sipgate and has a Sipgate Team 5 account. I have setup according to Sipgate, which is basically Open Box, plug in and enter user credentials, no need to change settings, set to DHCP client. I have the above problems.
The setup is as follows:
A brand new Netgear DGN2200 modem/router, plugged into 16 port switch.
3 different makes of modem/router do the same so not a modem/router issue??
In the switch are 2 phones which are dedicated Ethernet cables, 2 are pass-through to the PC. 4 PCs in total. 2 with phone pass-through, 2 just PC's. To be a pain, the two phones which are dedicated ethernet cables are having the second problem.
Windows Small Business Server 2011 - Setup as DHCP server and DNS server. Phone IPs are reseved. x.x.x.18, 19, 20 and 21. (arp -a reports correct devices on network)
SIP and RTP ports all open in router and setup in the phones. Sipgate shows correct external IP and SIP ports for all four phones.
5160/5104, 5260/5204, 5360/6304, 5460/5404
After a factory reset on each phone I ran a 5 minutes test to a cell phone which worked without problems, all 4 phones. I then called the office from my cell phone and answered the call on one of the phones. I then transferred the call to each phone one after another and back to the original phone, all without a problem.
I then called the boss to tell him about fixing it and it was the end of his problems. Calling his cell, on the call for about 1m 30s and it went quiet. I hung up and called him back. Same again, about 1m20s. He called the office and again the same happened. He could hear me swearing at the loss of incoming audio but I could not hear him. (maybe a good thing). I had even set the Qos in the router for each device as high priority.
Please, what is causing this issue? I am pulling my hair out. It also happens on calls to land lines during office hours. Not good for a business.
The second problem is that I have 4 calling groups and the standard Sipgate welcome message "If you know the extension......" (Bear with me)
Option 1 - All phones ring
Option 2 - phones 1 & 2 should ring
Option 3 - phone 3 rings
Option 4 - phone 4 rings.
I use option 1 and all phones ring. I try option 2 and the phones ring. Then leave it some time and do option 2 and I get unobtainable. Call again and use option 2, the phones ring. At 4am this morning, Option 2 rings first time, 8am, the phones did not ring, call a second time, they ring. It is as if inactivity kills the phone until an attempt to wake them. But at 4am I know 100% that they will have been inactive for hours so this makes me scratch my head more.
Are there any settings you would suggest changing as Sipgate basically say don't change anything, yet the GXP 2010 needs things changing... makes no sense to me how some settings need to be changed on one phone model, but the same option on the 2100 should not be changed??
Any suggestions would be great.
Many many thanks in advance.
