Cisco Telepresence ISDN Link with SX20

[nuno.lamelas]

Hi all,

I will implement a Cisco Telepresence ISDN Link with SX20.

The Scenario will be:

4 BRI Euro ISDN

IP infrastruture with static IP

NO VCS

It will be possible to dial IP and ISDN video Calls.

The isdn admin guide does not contemplates this scenario, and I can not find documentation to help me with this scenario.

Can someone help me how should I configure the endpoint and the ISDN link to work with my scenario?

Thanks in advance.

Hi , does someone knows if i have Sx20 registered in CUCM  and Sx20 is paired with isdn Link with Bri's , what is the behaviour if i dial external rdis number , ie , the cal goes to Isdn Link or to CUCM?

CUCM-SIP-SX20-SIP (PAIRED) - GW ISDN LINK - BRI-PSTN

I think if i dial H320: external pstn number i go through ISDN LINK , but if i dial only numbers i go routed to CUCM

Can someone explain better?

Regards

When calling and you just want audio, and no video, set the call rate in the dialling interface to "Audio Only" - that does the same thing as that old dial string parameter did (see screenshot below).

If you're seeing those things show in the interface on the codec or ISDN Link, it looks like you're probably running the old firmware versions.  As suggested previously, I'd strongly suggest you update to ISDN Link software version IL1.1.4 and SX20 version TC7.2.1.

Hi Slobodan,

No at all, you can dial directly a H.323, SIP o H.320 from your SX20, you have't use this dial string.

If your PSTN provider, put a PRIs or BRIs, in your ISDN link. You must say him that PRI or BRI should use vídeo and audio. For example if you are using 2 BRIs, you PSTN provider must configure these BRIs in bonding,...

Yes, you can use this ISDN Link for video and audio.

Check you versión of SX20 and ISDN link to get tha latest firmware versión.

Regards.

for test purpose i dialed on my mobile its shows error codec is not register with ISDN link

That's showing that there is an error with the configured PRI1 ISDN service.

What sort of ISDN service do you have (a PRI, or a BRI)?

Have you configured all the ISDN Service details correctly on the ISDN Link?
