SIP trunk - 1 provider 2 accounts

[ipohead]

I've got 2 separate accounts and credentials with 1 provider. Each account registers and can receive calls when only 1 is in service but when 2 are in service only one works (although both show as registered).

I've been advised to change the listen ports for each account but I can only seem to set a single overall listen port in System - LAN1 - VOIP. This is currently the default UDP & TCP 5060. How do I set this per account?

I think you have 1 SIP line with 2 SIP credentials. In this case, there is only 1 send/listen port.
You can have 2 SIP Lines for the same provider, each with 1 SIP credential. Now you can configure different send/listen ports.
You also may get confused about System, Lan1, VoIP where you also can configure listen ports, but this is for extensions, not SIP Trunks.

I have 2 lines with the same provider each with their own credentials.

If both are active, they both register and can make outgoing calls but line 1 rejects incoming calls.

In System - LAN1 - VOIP changing the topology to 'none' allow the listen port to be be set for each:

line 1 49160 line 2 49260

The provider's website confirms that these ports are registered.

I've spent some more time on this and it isn't really down to the ports.

and an old post here answered

IP Office 5.0+: If the wildcard * is used in the SIP trunk's Local URI, Contact and Display fields, that SIP trunk will accept any incoming SIP call.

Entering the * in R11.0 actually turns to 'auto' and now calls are accepted on both numbers but not simultaneously - I assume this is because it can't identify the line and will need some more work on URIs.
