Hi Iñaki, Thank you very much for sharing this information. I check the same in my server implementation with various SIP clients and hope this should work out. Best Regards, Vivek Batra -Original Message- From: sip-implementors-boun...@lists.cs.columbia.edu [mailto:sip-implementors-bou

Hi Iñaki, This is the exact problem. If server only uses domain based TLS certificates, SIP clients which have been used IP Address to reach server don’t accept that certificate and TLS binding gets failed. I was just trying to find out if there is any mechanism where multiple identities of server

Correction, I use the second recommended algorithm, which starts playing the tone on the first received telephone event and plays the tone until one of the 4 listed listed scenarios occur. This works pretty well as the algorithm is more responsive to dtmf than waiting for the end of the event to oc

Hi again Vivek, It occurred to me you're asking: when do you start processing the received telephone-event payload? I'm pretty sure this is implementation specific. My implementation processes tones on the first received packet (minding timestamp problems) which is the first recommended algorithm

Hi Vivek, To clarify are you asking how to specify RFC 2833 will be used between both ends of the call or when to set the market bit in a rtp event packet? I'm having trouble following your questions. FYI: RFC 2833 is made obsolete by RFC 4733. Thanks, Brandon -Original Message- From: s

For completeness... RFC 6026 updates RFC 3261 concerning proxy behavior when receiving responses for unknown requests. The following is from section 4 summary: "It also forbids forwarding stray responses to INVITE requests (not just 2xx responses), which RFC 3261 requires." > -Original M

Hi Folks, I have encountered one problem during SIP TLS session. I would appreciate your views on the same; During TLS binding setup from X-Lite Softphone to our IP-PBX, IP-PBX returns the server certificate to the X-Lite Softphone. Everything goes fine when IP-PBX is connected on public IP

Hi Folks, I would like to know is there any standard practice when to declare DTMF event in Outband (RFC 2833) viz 1. Whether immediately on receipt of Start Packet without waiting further for End Packet OR 2. On receipt of Start Packet followed by End Packet OR 3. On receipt of End Packe
