call forwarding to SIP URI

dialtone · March 15, 2011, 01:02:15 PM

Assuming that:
* There is one OBi110 device.
* There is an analog telephone connected to the OBi110 phone port.
* The OBi110 SP1 has been configured for the Google Voice account first@gmail.com
* The OBi110 SP2 has been configured for the Google Voice account second@gmail.com
* Inbound and outbound calls are working fine.

Can you do a "Call Forward ALL" to a SIP URI ?

In other words ...
An inbound call on SP1 would immediately forward to sip:abc123@XYZ.com
and
An inbound call on SP2 would immediately forward to sip:efg456@lmn.com

How would you do this?

I am not sure about OBi1 110 setup for this and limitations, but at least to call sip URL you must have Sip service provider which you do not have.

Get two IPkall accounts and you will be able to do what you want even without OBi.

GV will ring your IPkall number and then you set forwarding to sip URI in IPkall.

Hi,

Apparently you can cal via URL with GV.
sip:+1NPANXXXXXX@sip.voice.google.com

See this site for info:

No, this is not right. You cannot call SIP URI using GV account.
You can call Google Voice number using sip Uri with sip provider and only if that sip provider have peering with GV network.
For example you can call from Gizmo to GV with SIP uri, but not from GV to sip.
Google Voice just does not have an option to dial SIP URI.

ip:+1NPANXXXXXX@sip.voice.google.com

This times out trying to call your GV number from Sip Sorcery.

Does OBiNet reject all the SIP URI calling requests from OBi endpoints?

Unfortunately Google Voice has enabled and then disabled this capability on several occasions. It worked for a time yesterday morning (March 16) but by the afternoon was disabled again.

dialtone,

I cannot think of a solution for your case, since both SP1 and SP2 are configured to use GV protocol.
But suppose you have SP2 still using a SIP ITSP (SIP Protocol), then what you want can be done for
SP1 (GV). That is, call forward incoming calls on SP1 to a SIP URL. The call forward destination number would be something like this: sp2(12345@xyz.com).

The reason is that the OBi is relying on at least one SIP trunk to perform SIP transactions.

Thanks obi-support2,
I understand. I need atleast one SIP ITSP (SIP Protocol).

As MichiganTelephone pointed out, unfortunately the Google Voice SIP URI capability is not reliable.

Based on the above, can the call be forked to both SP1 GV and SP2 (12345@xyz.com) ?

Take a look at this posting:

Also, you can only use a SIP URI with an SPx that is configured for SIP.
