I have setup topex mobilink IP gsm as a sip gateway in cucm 8.6. and assigned specific extension (3550) to have external call feature. incoming call to mobile(gsm sim card number) number routed to 3550 without any issue but outgoing from 3550 extension connected with dead air( no audio at both end).
when I check the call status on my 7960
rcevr and sender codec - g711u
rcevr and sender time - 20ms
send pckts - 1250
rcevr pckts - 0
end to end devices have ip connectivity ( ip phone gsm-gateway)
no audio issue is only with external call via gsm gateway from 3550
