Hello all,
- incoming calls work very well in this router OK
- outgoing calls never have work in this router NOK
outgoing call flow for this issue: IP phone-->(SCCP)-->CUCM-->(SIPtrunk)-->C2901-->(E1)-->SP(PSTN)-->cellphone
- This issue fails all the time. When you make a call from the IP Phone, it sounds on the cellphone but when I pick up there is no return on the IP Phone. The IP Phone is still calling.
