Description:	Currently, {{res_sip_dtmf_info}} will parse an SDP that looks something like the packet below: {noformat}  <send retrans="500"> <![CDATA[ INFO sip:test@[remote_ip]:[remote_port] SIP/2.0 Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch] Max-Forwards: 70 Content-Length: [len] From: test1 <sip:guest1@[local_ip]:[local_port]>;tag=[call_number] To: test <sip:test@[remote_ip]:[remote_port]>[peer_tag_param] Call-ID: [call_id] CSeq: 2 INFO Supported: timer Content-Type: application/dtmf-relay Contact: sip:test@[local_ip]:[local_port] Supported: replaces User-Agent: Aastra 480i Cordless/1.4.3.1001 Brcm Callctrl/1.5.1.0 MxSF/v3.2.8.45 Signal=1 Duration=160 ]]>  </send> {noformat} Unfortunately, sometimes DTMF is sent without any parameters, i.e., no "Signal" or "Duration": {noformat}  <send retrans="500"> <![CDATA[ INFO sip:test@[remote_ip]:[remote_port] SIP/2.0 Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch] Max-Forwards: 70 Content-Length: [len] From: test1 <sip:guest1@[local_ip]:[local_port]>;tag=[call_number] To: test <sip:test@[remote_ip]:[remote_port]>[peer_tag_param] Call-ID: [call_id] CSeq: 2 INFO Supported: timer Content-Type: application/dtmf-relay Contact: sip:test@[local_ip]:[local_port] Supported: replaces User-Agent: Aastra 480i Cordless/1.4.3.1001 Brcm Callctrl/1.5.1.0 MxSF/v3.2.8.45                1 ]]>  </send> {noformat} That's a DTMF "1". The duration is inferred. The module should be able to handle this as well.
