You need to go with Cisco ATA 190 which is SIP based since ATA 186[SIP/SCCP] ,187[SIP] and ATA 188[SIP/SCCP]. But all are End of Sale.
I'd never heard of the ATA 190. Thanks for the heads-up!
Looking at the product page of the ATA 187, I can't see any end of sale notice for it. Do you have a link for this?
Silly me, the link to the ATA 187 End of Sale notice isn't on the ATA 187 product page. Why would anyone think of putting a link there?
You could use a VG202. That supports SCCP. But a VG202 is insanely expensive. Why do you need an SCCP ATA?
Not sure what your call control platform is, but there's nothing in CUCM stopping you having the same number on devices with different protocols. I'm sure here we've got numbers on both SCCP & SIP devices.
when I use the same number on sccp7965 and another sip phone, and when calling this number both phones do not ring together. ringing only sccp phone. and it is impossible to hold call on first sccp phone and resume call on sip phone
I've just checked our cluster, and this definitely works. (We're on CUCM 9.1 too)
I suggest you start a new thread here to investigate why your scenario isn't working.
