I'm just wondering, have anyone able to configure a SIP extension successfully on a Polycom Trio 8800 unit? I was able to register the unit on an OS7100. I can call to the unit internally with an extension, or externally with a cell phone, but I'm unable to dial out on the Polycom unit internally to an extension, or externally to an outside number.

Any idea why?

Sounds like you need to create/modify the dial plan on the polycom.

Anything sip is enbloc dialling, so you have to configure the number plan so it knows how many digits to wait before dialling.

Since the SIP extension is registered. Is it suppose to use the Samsung Officeserv dialplan?

No, a sip extension isn't the same as a ip extension, you have to manually configure the dial plan, this includes local stations and external numbers (don't forget to include the trunk group/lcr digit)

I configured this Polycom Trio 8800 the same way as I configured the Polycom IP SoundStation 6000. I had no issue with calling in and out with IP SoundStation 6000 unit, and I never had to configure any dialplan on the Polycom unit.

Anyway, I'll look into that. Thanks!

I modified the digitmap(dialplan). I still couldn't get to anywhere.
I called Polycom support. They redirected me to contact a reseller. Called reseller, and they directed me to contact another supplier. Called supplier, and they directed me to Polycom. -_-"
Called Polycom again, and they directed me to an authorized VOIP partner.

Today, I'll call that authorized VOIP partner, and see what happen.

Just curious, do you have number formatting enabled or disabled?

As polycom is a us company they ship the phones with a NANP dial plan.
Our number plan is rather different, so we always had to change it. Same with the cisco/linksys ATA's

I had an authorized CPC support contacted me. I sent them a debug log, and phone configuration. It appeared my dialplan, and phone configuration are correct. Here was their reply:


It looks like the Samsung PBX does not support video so it is rejecting the call instead of just leaving video codecs out of the caps exchange.

Fortunately, there is a way around this. We can disable video on line 2 so the phone will not send video codecs in the caps exchange. The parameter for this is reg.2.video.enabled="0"


I'll get my customer to make some test calls, and I'll keep you guys post it.

Got a call back from customer. They can call out now with the Polycom unit!!

After all the phone calls, and the issue was caused by reg.2.video.enabled="0". Which you don't even have an option to click "no" on the web interface. You have to import the parameter with a configure file.

Anyway, issue solved. Hope this post will help others who might fell into the same issue.
