Hi
We recently cross an issue where one way audio when answer from hunt queued calls and call flow as below:
ITSP ---sip---> CUBE(SP) --- sip--> CUCM --- sip---> ip phone
PSTN caller 1 call the hunt and answer by IP phone with 2 way audio. Then 2nd PSTN call coming into hunt which configured for Native queuing and 2nd call is queued as all hunt members are already on the call and PSTN caller 2 hear music on hold. IP phone disconnect PSTN caller 1 and PSTN caller 2 previous queued is ringing to IP Phone and PSTN caller 2 start hear ring back tone. IP Phone answer the call and one-way audio occurs where PSTN caller 2 can hear IP Phone but IP Phone cannot hear PSTN caller 2 (same call flow works perfectly fine when all calling and called party from internal ip phone).
Has anyone came cross similar issue and any suggestion?
