Freephoneline.ca OBi110/202 Registration Period RESOLVE

I need your help setting up OBi110/202 with freephone settings  http://support.freephoneline.ca/entries/23120323-VoIP-Unlock-Key-Credentials. I have been using the default setting for a year without any problems. However, in the last week OBis report Register Failed: 486 Too many requests. (OBi202 concurrently runs another SIP provider without any issues.)

Required settings:
1. IP Server: voip.freephoneline.ca
2. Alternative SIP Server: voip2.freephoneline.ca
3. Transport: UDP
4. Port: 5060
5. Registration Interval: 3600 seconds (1 hour)
6. Registration Expiry: 3600 seconds (1 hour)
7. Failed Registration Re-Try Interval: 120 seconds

Please refer to OBiTALK in your answers. Variables have descriptive names and I know some of this may look obvious but please have patience.

Q1) Is there a field to enter an Alternative SIP server?



Q2) In ITSP Profile SIP-> RegistrationPeriod=60 by default. Change it to 3600?

Q3) In ITSP Profile SIP->RegisterExpires=3600 by default. Keep the same value?

Q4) In ITSP Profile SIP->RegisterRetryInterval=30 by default. Change it to 120?

Recommended Settings:
A. STUN/ICE: Disable
B. NAT Mapping Enabled: Yes
C. NAT Traversal: Enable sending Keep-Alives only. On Grandstream HT-701 ATAs this setting is “no, but send keep-alive”
D. Keep Alive Message: NOTIFY or a UDP PING Packet. For Linksys/Cisco devices, use ‘Nat Keep Alive Msg’ = $NOTIFY or $PING. Never use REGISTER as your Keep Alive message
E. Keep Alive Interval: 20 seconds*
*Audio may be affected if this value is adjusted

Q5) There seem to be two relevant keep alive fields: ITSP Profile RTP->KeepAliveInterval=0 by default (i.e. disabled) and SP Service->X_KeepAliveExpires = 15 by default. Which of the two needs to be set to 20?

Q6) What about A, B, C and D? Are they the default values on OBi?

RTP Settings:
Supported Codecs: g711-u (uLAW) and g729
Suggested RTP Packet size (psize): 0.020  - This ensures audio packets every 20 milliseconds, achieving better quality (trade-off: bandwidth)

Codecs settings seem to correspond to default OBi settings.



I am not an expert, but in my freephoneline configuration, I have the following non-default entries (I do not use Obi portal, BTW, I access the device directly via it's WAN interface):

• ITSP Profile -> SIP -> ProxyServer -> voip.freephoneline.ca
• ITSP Profile -> SIP -> RegistrationPeriod -> 180

Everything else is set as default and I have no problems for the last few months. YMMV. Separately, I have my router configured with QOS settings to prioritize VOIP traffic.

RegistrationPeriod that need to be changed from 60 sec to 3600 sec

the RegistrationPeriod is located in the Expert menu under

Service Providers > ITSP Profile X SIP > RegistrationPeriod

Uncheck the Obitalk Settings and then the Device Default and change the value for 3600

That should fixed the "486 Too many registers" Error Message

Default Value
RegistrationPeriod:  60
