this is the sip flow when i made the call, but fail (nothing went through)
I’m sorry, but didn’t you put in too many codecs? Tried for example only with PCMU?
This is not a call. A call will be an INVITE. This is a register and I guess you need to check the router and with the provider.
hmm, i have always use the default options. i will try your suggestion and report back.
yes. what i meant was the capture was made when the calls are being made, but failed to get through. i will try with another router tomorrow. i have an identical router but without latest firmware. i updated the current router with latest firmware. will test and report back.
