I have set up a chan_sip trunk for use with voip.ms. The outbound settings are:
username=127304_SANMIGUEL type=peer trustrpid=yes sendrpid=yes secret= qualify=yes nat=yes insecure=invite host=losangeles.voip.ms fromuser=127304_SANMIGUEL disallow=all context=from-trunk canreinvite=nonat allow=ulaw
The incoming string is:
The provider tells me that I am only sending the character ‘G’ in the initial INVITE so the registration is failing. Their support gave me a pcap file which doesn’t show this string anywhere in it so I’d like to know exactly how to determine what is being sent as a registration string. The support from voip.ms has not been of much help.
