Solved: Sip trunk between CCM 4.x and UC500

mirkomaffioli · ‎06-20-2008

Hi,

It's possible to create a sip trunk between a CCM 4.x and a UC500 in order to use the CCM as pstn gateway and permit internal voip calls?

Thanks

Then yes,

- on the CCM configure voip trunk as per documentation

- on the voice GW configure DP so that call to certain numbers (hopefully you've ISDN) can go to CME

- on CME configure a voip DP with destination-pattern the numbers that are on the CCM, ipv4 address and codec g711u. Also configure a destinaion-pattern for PST calls having session target the other GW.

Hope this helps, please rate post if it does!

Only use H.323 or SIP for trunking.
