[Cannot set up PSTN trunk with Grandstream HT-503]

Thank you for your responses, i appreciate it.

 

I know the HT isn't the best gateway but i am simply using it as an experiment to test interoperability of pbxnsip with OCS, when the time is right i will change this adapter for something more capable.

 

I have done what you have suggested and now i don't seem to get any errors in the log. I cannot call the outside world however. Thing is, the adapter is plugged this way:

 

HT-503 - Analog PBX - PSTN.

 

If i pick up the phone connected to the HT i get a dialtone. If i press 9 (which is what i've set as the PSTN access code in the ATA) i reach my analog PBX here at work. If i press 9 again i reach the outside world.

 

I have tested that if i dial the entire number all at once (for instance 9988536491) the call will go through, i don't have to wait for dial tones from either the HT or the analog PBX.

 

How would i go about creating a dial plan for this? I have set a single one saying that any 8 digit call should be replaced with 99 and the 8 digits and it gets recognized in the log:

 

[5] 2010/02/23 17:33:45: Dialplan Dial Plan: Match 88536491@192.168.230.170 to <99xxxxxxxx> on trunk PBX

 

however the call never gets through, it just keeps ringing.

 

Any clues?

 

Thanks

I'm pulling my hair out here.

 

All i need (for now) is sip registration from pbxnsip to a Grandstream HT-503.

 

Both my ATA and pbxnsip are on the same subnet. HT's IP is 192.168.230.180 and pbxnsip's is 192.168.230.170.

 

I can register soft phones with pbxnsip. I can also call the analog phone connected to the FXS port of the gateway.

 

HT's settings are as follows:

 

Primary SIP Server: 192.168.230.170

Outbound Proxy: 192.168.230.170

SIP User ID: 10000

Password: 10000

SIP Transport: UDP

 

PBXNSIP's settings are as follows:

 

Type: SIP Registration

Display Name: 10000

Account: 10000

Domain: 192.168.230.180

Username: 10000

Password: 10000

Outbound Proxy: 192.168.230.180

 

Everything else is at default settings.

 

The error i get on PBXNSIP is:

 

[2] 2010/02/22 12:35:53: Trunk status PSTN (3) changed to "405 Method Not Allowed" (Registration failed, retry after 60 seconds)

[5] 2010/02/22 12:36:53: Registration on trunk 3 (PSTN) failed. Retry in 60 seconds

 

If i reset the ATA i get:

 

[5] 2010/02/22 12:50:30: SIP port accept from 192.168.230.180:2050

[1] 2010/02/22 12:50:30: TCP: TOS could not be set

[5] 2010/02/22 12:50:53: Registration on trunk 3 (PSTN) failed. Retry in 60 seconds

 

Thanks for your help.
