Testing outgoing calls with SIP provider and getting quite odd result.
CUCM 6.1 - trunk - CUBE-- (FW) -- inet -- SIP provider -- PSTN
When I call PSTN number via my SIP provider PSTN phone rings. When I answer the call is ended on PSTN end but my phone keeps ringing.
voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
fax protocol cisco
no h225 timeout keepalive
dial-peer voice 99 voip
session protocol sipv2
session target ipv4:220.127.116.11
CUBE is registered with SIP provider and I'm sending correct number as CLID.
Looks like problem with signaling but not sure where is problem. Between CUBE and internet there is firewall doing NAT but tried different options and same results.
Any help really appreciated.
