Remote Presence

Hi,

I have CME version 10.5, and combination of SIP & SCCP phones.

This is about remote presence using BLF speed dial.

- SIP phone (8851) on site A can view SCCP ephone dn on the same site -> OK

- The same SIP phone on site A can't view SCCP ephone (number 201) on site B -> ???

- SCCP phone (8945) on site A can view the same SCCP ephone dn (number 201) on site B -> OK

Strangely, when I first configured the remote presence, it worked perfectly. But now it's suddenly broken, have restarted the CME on both sites, didn't solve it.

Can somebody with remote presence experience help?

Thank you.

Igo,

according to the CME admin guide, the following applies, between trunk connected phones.

what are you using to tie the two locations A and B together.?

Restrictions for Presence Service

  • Presence features such as Busy Lamp Field (BLF) notification are supported for SIP trunks only; these features are not supported on H.323 trunks.

  • Presence requires that SIP phones are configured with a directory number (using dn keyword in number command); direct line numbers are not supported.

Hi Dennis,

Thanks for the information.

The 2 locations are connected using VPN (SIP trunk).

Given the fact that using BLF speed dial, SCCP phone (8945) on site A can view SCCP phone (8945) on site B, I think the SIP trunk has been configured correctly, please correct me if I'm wrong.

But SIP phone (8851) on site A can't view the same SCCP phone on site B.

What configuration can cause this?

Thanks.

Please see below the related config on CME site A.

I can't get SIP phone (voice register pool 3) on CME site A to watch ephone dn 201 on CME site B.

While, this is working:

- SCCP phone (ephone 4) on CME site A can watch ephone dn 201 on CME site B.

- SCCP phone on CME site B can watch ephone dn 3333 on CME site A

Any idea?

Thanks.
