Hi Guys,
I'll start by saying that I'm pretty green when it comes to both Asterisk and Freepbx. I've setup an Asterisk Now VM at home and having been playing with Freepbx for a few weeks. Everything I touched worked which is a testiment to the developers hard work however I was only using extensions, no SIP trunk configured yet.
Last week I decided to bite the bullet and I bought a Cisco 7940G and signed up for a SIP trunk with a local provider. No issues getting the Cisco 7940G working or the SIP trunk. In fact it was probably a bit to easy. I configured my dial plans on the outbound route to allow Irish landline numbers for all area codes (and there is a lot in this country) and all tests worked fine. Now, this is where it all started to go weird for me.
I added the dial plans for Irish Mobile numbers and the Cisco Handset and any of the Desktop SIP clients I was testing with were working fine. They could all dial out with no issues however the Mobile SIP clients were recieving a 603 Declined error. I researched this to the best of my ability and I believe that it's a Codec Mismatch issue. I'm only using the free SIP clients for IOS and Android at the moment so I'm relying on ULAW and ALAW for codecs. The strange thing though is if I dial a specific LandLine number the Mobile SIP clients work fine but only for 1 landline number.
Would anyone have any advise for me on what I could look at here. If you need any further information from me just ask away.
Cheers,
Laoistom
